Is a rectifier supposed to get hot?
It’s normal for an OEM shunt-type regulator/rectifier (RR) to get quite hot — especially when the load being drawn by the electrical system is low. The RR is simply converting excess stator output wattage (that isn’t needed to run the bike and charge the battery) to heat. That’s why there are cooling fins on the RR.
How to test a Yamaha regulator / rectifier?
Yamaha Regulator/Rectifier Test The forward bias measurement for the negative terminal diodes in the Yamaha regulator/rectifier should be about 0.48 volts to 0.52 volts, and the positive terminal diodes should be about 0.12 volts.
What should the forward bias be on a Yamaha rectifier?
The forward bias measurement for the negative terminal diodes in the Yamaha regulator/rectifier should be about 0.48 volts to 0.52 volts, and the positive terminal diodes should be about 0.12 volts.
What causes the stator on a Yamaha Virago to fail?
Stator Failure: As the regulator, the stator is a critical part, and since they’re an older bike, owners of a Yamaha Virago should be inspecting their stators constantly. Some suggest years exposing the stator to pronounced heat and vibration may be the reason for the failure.
How do you connect a rectifier to a terminal block?
Remove the rectifier wires from the terminal block. Using a ohm meter, connect the black lead of the ohm meter to the rectifier base (ground), then one by one, connect the red lead of the ohm meter to the yellow, yellow/gray, then the red wire (some rectifiers may also have a fourth yellow/blue wire. If so connect to that also).

What should I do if my rectifier gets hot?
Second you need to make sure that your fuse is a small as possible that will handle the current draw of the device. too large a fuse and you will not have the protection that a fuse in a circuit is designed to protect. What are you plugging into your 12V outlet?
What are the symptoms of a bad rectifier?
There is no intended relationship between the rectifier and the igniton system. The battery charge question…. That creates no problem UNLESS you accidently hook the charger up backwards. Reverse polarity will blow the rectifier instantly. Re: Symptoms of bad rectifier?
