xr250 regulator/rectifier

Recommended Posts

How can i test my regulator/rectifier to see if it's working?

I've got an 1989 xr250r and the lights, blinkers and horn don't work.

What should I do?

Use a multimeter, run the engine at fast idle, check the output voltage out of the regulator, should be 13.5 - 14 volts

First, see if there's an inline fuse that's blown.

Just did this and got no output voltage. Does this mean that it's fried, do I kneed a new one?

Output voltage of the alternator is the input voltage to the reg/rec. So the alternator is what is making the electricity in the first place. So that means it is that ring of coils(stator) under the left side engine cover.

Is this under the seat?

Thanks for the info guys, I found that one of the wire connectors from the alternator was covered in blue stuff and stopping the connection, I cleaned it and now it works.
