how to test a motorcycle rectifier

Generally, the three yellow wires connect to the three wires from the stator. How to make a reliable motorcycle voltage regulator. So the more modern equivalent AFTERMARKET RECTIFIER is potted in an epoxy resin encapsulant. If you are unsure of your skills, it’s best you take your motorcycle to a qualified technician. © 2020 Rick's Motorsport Electrics Blog and more. So it just runs the battery down because its getting no charge at all. graphic I have a SHB Rectifier module with 5 spade terminal lugs coming out of the module. We were given a three-phase selenium rectifier, taken from an ancient Honda 150 motorcycle. You cannot test the new MOSFET regulator/rectifiers in this way, as they don’t use standard diodes. Next, connect your negative lead to the stator inputs. Rick's Motorsport Electrics Blog and more, Latest Barn Find: Suzuki GS1000S Wes Cooley Replica, 3 Things You Can Do With a Vintage Motorcycle, Ricks motorcycle Safety Tips + the Top Tips from Our Customers, How to Start a Snowmobile That Has Been Sitting. Please check with an experienced GSR member before using a part you picked up from ebay. Because the stator is producing power according to the engine-speed the stator-output is too high all the time. You can only test the diode function of your rec/reg. Save my name, email, and website in this browser for the next time I comment. The is now DC, and can be used to charge the battery! The ground wire should get connected directly to the negative battery terminal. This rectifier is for the bikes with a 3-wire rectifier. You should produce a set of 8 numbers – follow the process below, and write the numbers down as you go, so you don’t lose track. Item Type: Rectifier. With nothing connected, the needle will be at rest, over to the left. If the readings are not within the normal range, it is time to begin testing the charging system components. 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. Most Digital Multimeters have a diode test setting. How to test your Honda CT90 rectifier with a multimeter in full color illustrated easy to understand instructions. 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 … 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. Pitbike rectifierregulator wiring diagram isaac p. This is the ultimate guide to the humble motorcycle regulator rectifier. To test the rectifier, connect your Ohmmeter to one of the wires and the ground/mounting stud of the rectifier and record the reading. Ok, bringing this one back. 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. Also bear in mind that some of the combined regulator/rectifiers have capacitors in them, which will also affect your results. Now reverse the leads from the ohmmeter and note the reading again. You will be looking for a voltage range of 13.2 Volts DC and 14.8 Volts CD. Set your multimeter to measure DC voltage and connect the positive and negative leads to the matching battery terminals. 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. It looks like this: A popular upgrade is to combine the rectifier and regulator (the zener diode) with one, single unit. Set the multimeter to “Resistance” or “Ohms” on the lowest scale, and insert one probe into one of the stator pin sockets. You will be looking for a voltage range of 13.2 Volts DC and 14.8 Volts CD. This measures the forward bias voltage of a diode (i.e. First, check the positive diode. In the tests below – the green arrow on tests 1, 3, 5 and 7 indicate that you should see a value on your multimeter. Start the motorcycle and rev the motor to 5000rpm. How to Test a Motorcycle Rectifier The motorcycle’s rectifier is another part of the charging system. For example, on a 1981 Kawasaki KZ440, there are 5 wires going to the OE part: 2 yellow wires (AC inputs), white/red (DC “+” output), black/yellow (DC “-“ output), and a brown wire. For example, my Avo doesn’t. If you believe you are qualified to proceed, then the next step is to check running voltage across the battery. 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). The gray three-terminal connector receives power from the stator, and the black two-terminal connector sends power to the battery. Using the multimeter, test the same battery terminals again.
