Also bear in mind that some of the combined regulator/rectifiers have capacitors in them, which will also affect your results. The exact reading is not all that important, but there should be a … Required fields are marked *. Here I am only testing the regulator portion of a common Regulator/Rectifier. You should receive a reading of 13.5 to 14.5 volts if your rectifier-regulator is functioning correctly. You cannot test the new MOSFET regulator/rectifiers in this way, as they don’t use standard diodes. With nothing connected, the needle will be at rest, over to the left. Hopefully this will help someone somewhere! eBay Motorcycle Rectifier Regulator Review. Luckily, you can now get a Rick’s Hotshot rotor and overcome the [...]. These components are probably the most mis-diagnosed parts in the charging … Generally, the three yellow wires connect to the three wires from the stator. If the readings are not within the normal range, it is time to begin testing the charging system components. However, most of the regulator/rectifiers in the market (examples include Podtronics, Boyer Bransden Power Box and Tympanium) are simple and easy to test. I suspect I have a bad Regulator/Rectifier unit as I am getting A/C from the alternator into the unit but when rev'd I get nothing out. Fit for XL600 XL600R 1983-1987 Motorcycle. Start the motorcycle and rev the motor to 5000rpm. Especially fit for XL600 XL600R 1983‑1987 Motorcycle. Selenium rectifiers are recognizable by the cooling fins, which are often painted green or orange. Auto VR is a stabilizer. Without a functioning rectifier-regulator, a weak, dead, or overcharged battery would be the result. This will make sure it doesn’t find it’s way back on to a bike in the future!!! Many Rick’s Motorsport Electrics Rectifier/Regulators eliminate what is commonly referred to as a “signal wire” on OE pieces. © 2020 Rick's Motorsport Electrics Blog and more. Because the stator is producing power according to the engine-speed the stator-output is too high all the time. This measures the forward bias voltage of a diode (i.e. Motorcycle Regulator Rectifier Connectors Regulator and rectifer, generator and stator wiring connector plugs that are used on older and modern Japanese motorcycles using the unsealed 6.0mm and 6.3mm terminals to the modern Honda, Suzuki,Kawasaki and Yamaha that use the sealed type connectors. To test the rectifier, you will need to disconnect all of the wires and turn your multimeter to the diode function. How to Test a Motorcycle Rectifier The motorcycle’s rectifier is another part of the charging system. If you have a factory original rectifier, make sure you have a new battery in your multimeter – the diodes are chunkier than on the modern equivalents. Now reverse the leads from the ohmmeter and note the reading again. If you’re restoring your vintage Honda or Kawasaki motorcycle, one of your key priorities should be getting an upgraded rotor. Follow the instructions below, alternatively click here to download a set of instructions that you can print out. There are two connectors on the regulator/rectifier. The is now DC, and can be used to charge the battery! You will be looking for a voltage range of 13.2 Volts DC and 14.8 Volts CD. To service these bikes I add a removable ground wire so it can be used for … This is where the Rectifier comes in to play. To test the rectifier, hook up the ohmmeter leads to one of the wires and to the ground (mounting) stud. So it just runs the battery down because its getting no charge at all. Total failure All of the parts share a common ground or hot connection; if the unit tests out totally dead, then this internal connection could have failed. As the magnets in the rotor spin round they excite the coils of wire which are embedded in the green resin on the stator. The display will read “OL” which means “Open Line” when there is nothing connected to your test leads. Most Digital Multimeters have a diode test setting. The ground wire should get connected directly to the negative battery terminal. A Rectifier is the part of the charging system that convert the AC voltage from the alternator into DC voltage which can be used to charge the battery. AC is fine for making a lightbulb glow, however in order for it to be used to charge a battery, it needs to be converted into DC instead. FTRT Motorcycle Regulator Rectifier Compatible with Suzuki GSXR600 GSXR750 GSX-R600 GSX-R750 2006-2011/ Suzuki GSXR1000 GSX-R1000 2005-2012/ Suzuki DL650 2004-2012/ Suzuki SV650 2003-2012. This is because older motorcycles often have inadequate charging systems, depriving you of a lot of potential power. the volt drop as current passes through in the right direction). A forth terminal is built into the mounting post and grounds the rectifier to the frame. 99. With your test leads connected to each other, the needle will be at the opposite end of the scale resting on the stop – reading 1. Place the red probe (+) on the anode the diode. As always, the internal electronics and overall build quality of motorcycle regulator rectifiers vary between manufacturers. How to Test a Motorcycle Rectifier using a digital multimeter The multimeter should be set to Volts DC. Put the multimeter's negative lead on the positive terminal of the black two-terminal connector. With your leads connected to each other, your multimeter will read 0. Only newer analogue mulitmeters will have a diode setting. First test the condition of the Battery. This rectifier is for the bikes with a 3-wire rectifier. Types of Motorcycle Regulator/Rectifiers There are two main types of alternator that are fitted to most motorcycles, each requiring a different type of regulator rectifier. 4.2 out of 5 stars 53. Set your multimeter to 20 volts DC (Direct Current) and connect the positive (+) and negative (-) leads to the corresponding battery terminals. But that’s no problem. Set your multimeter to measure DC voltage and connect the positive and negative leads to the matching battery terminals. Regulator/Rectifier Test #1: Forward Bias of Positive Circuit Diodes. The OEM 3-wire rectifier is not what it appears to be. NOTE: When testing a regulator/rectifier, set your multimeter to the diode setting. To do this, place the positive lead into the positive diode. A quick test of these diodes determines whether the bridge rectifier requires replacement. It looks like this: A popular upgrade is to combine the rectifier and regulator (the zener diode) with one, single unit. Tagged as: 49072, AC, alternator, boyer bransden, boyer power box, DC, LU49072, lucas, lucas 49072, POD-tronics, podtronics, power box, powerbox, rectifier, rotor, stator, tympanium, voltage, Your email address will not be published.

You should receive a reading of 13.5 to 14.5 volts if your rectifier-regulator is functioning correctly. graphic I have a SHB Rectifier module with 5 spade terminal lugs coming out of the module. The rotor is mounted directly to the engine’s crankshaft. We were given a three-phase selenium rectifier, taken from an ancient Honda 150 motorcycle. If you believe you are qualified to proceed, then the next step is to check running voltage across the battery. This is the place a rectifier or can say the regulator come into existence. Here is a picture of a Lucas alternator rotor (the magnetic bit in the middle) and stator (the bit round the outside with the wires coming out of it). Ricks Motorsport Electrics offers the industry’s most reliable OEM rectifier-regulators, including a full line uniquely designed to also work with lithium ion batteries. Identify the markings on the bridge rectifier. Motorcycle VR regulates the output voltage of the generator. Note the reading you get. So i have done my best below to make it easier to understand. First, check the positive diode. The AFTERMARKET REGULATOR/RECTIFIER looks something like this: There are some new types of regulator/rectifiers that can not be tested simply, because they contain microchips and specialist circuitry inside them. Check out the blog by visiting the website below. Then connect the negative lead to each of the stator inputs. Motorcycle VR is a rectifier + stabilizer. Watch owner Rick Shaw explain how to test your stator in our informational video. Having a functioning rectifier regulator is one of the key elements to maintaining a healthy and reliable motorcycle. Some parts have 5 wires, some 6, some 7, and you have to know how to connect the wires properly. Your battery should be charged, giving you a reading at or just above 12 volts. Your battery should be charged, giving you a reading of approximately 12.5-12.9 volts DC (check your particular battery’s specifications for exact numbers). Item Type: Rectifier. The selenium rectifier replaced the vacuum tube rectifier in the period 1950 onward and was in use until the 70’s. If it’s higher, operating the motorcycle could be causing damage to your battery as well as any voltage-sensitive electronics on the vehicle. With the Battery on the bike and connected … To determine that the regulator/rectifier is working properly, it's necessary to test each of its diodes. You can only test the diode function of your rec/reg. Make sure you throw the defective part away, rather than put it in a drawer in your workshop. For example, my Avo doesn’t. Please check with an experienced GSR member before using a part you picked up from ebay. Set the multimeter to “Resistance” or “Ohms” on the lowest scale, and insert one probe into one of the stator pin sockets. All Rights Reserved. Using the multimeter, test the same battery terminals again. The rectifier regulator converts AC power to DC allowing the alternator to charge the battery, and controls the amount of power delivered to the battery. Next, connect your negative lead to the stator inputs. Use a 12 volt battery with an ampere-hour rating of at least 18 AH. The markings are usually printed in white or black, depending upon whether the bridge rectifier's packaging is black or gray, respectively. $29.99 $ 29. IGNITION OFF. Regulator rectifier diagram here you are at our site this is images about regulator rectifier diagram posted by maria nieto in wiring category on may 08 2019. Your email address will not be published. For the remaining tests – the STOP sign on tests 2, 4, 6 and 8 shows no voltage is flowing. Set the meter to read Ohms – it is the greek alphabet Omega symbol. If you are seeing lower readings, that implies that there is a failure in your charging system and the rec/reg may be the culprit. Step 1. Although the principle operation of regulator rectifier devices is the same, there are many different specifications, formats and designs. Most modern multi-meters come with a diode test function. The regulator side is not part of these tests – you should monitor the output across positive and negative cables when the reg/rec is connected to a fully charged battery. Using the multimeter, test the same battery terminals again. In the case you are experiencing these symptoms, a digital multimeter can be used to test the rectifier function. With your test leads connected to each other, the needle will be at the opposite end of the scale resting on the stop – reading 1. First perform the static stator tests. If the readings are not within the normal range, it is time to begin testing the charging system components. You could also perform some basic postmortem checks on the regulator/rectifier itself, and attempt to determine what has failed, internally if you have the necessary test equipment. So all I need is the numbers to what the combo reg/rec should test with a multimeter, but I cant seem to find them. Check the resistance between the pins and earth (the chassic, or the negative terminal of the battery). The “Full Wave Bridge Rectifier” to give it the correct name uses four diodes which basically takes everything below the green line, flips it, and puts it above the line! Touch the other probe to any chassis ground. Get it as … Click here to learn more. Click here to download a set of instructions that you can print out. In this piece of writing, we will try to address “what does a rectifier do to a motorcycle?” We will try to understand the underlying working of the rectifier and how it is responsible for providing DC power to … If the readings are not within the normal range, it is time to begin testing the charging system components. If you are not seeing the desired values on just one of these tests, it means that you have a malfunctioning component (diode) within the rectifier. We have expanded our line of aftermarket dirt and off road stators including for Honda stators, Yamaha stators, Suzuki stators and stators for KTM applications. With the engine off: Check the resistance between each of the pins (if there are just two, then the resistance between the two). Place the black probe (-) on the cathode the diode. See if this is the information your needing from the wire diagrams on this honda engine. To test the rectifier, connect your Ohmmeter to one of the wires and the ground/mounting stud of the rectifier and record the reading. The gray three-terminal connector receives power from the stator, and the black two-terminal connector sends power to the battery. There are motorcycles with automotive-type generators, but there are only few of them. How to make a reliable motorcycle voltage regulator. This value will vary per unit but importantly the value from all four readings should be the same or very nearly the same. , giving you a reading of 13.5 to 14.5 Volts if your rectifier-regulator is functioning as it should negative.
