thespirit Posted July 1, 2006 Share Posted July 1, 2006 Some of the things I have done is test the rectifier, and it seems good. I tested the coils on the stator and they are all within the right resistance. I tested from ring to ring on the rotor (brushes out), and there is 5 ohms resistance. The only thing that I thought was odd, was the brushes were connected together. The brush with the smaller metal clip was screwed into the top left of the holder (left side of the holder) and the one with the larger clip was on the right side with it screwed into the top left, top right, and bottom right. There was no connection to the bottom left screw. With the brushes out, there is a 36 ohm resistance between the two brush wires. I posted to a mailing list about it and they said they are not supposed to be connected together. So I took them back out and connected it so the left brush (small metal clip) is connected to the bottom left screw (shorter wire, non frame ground), and the right brush is connected like it was before. I put it all back together and tried to start it and it rolled over once and then everything quit. I checked the main fuse and it's blown. (It was not blown previously)... I have very little experiance and am trying to get as many opinions as I can. Pictures of how the brushes are supposed to screw in would be ideal. My way of thinking is that the brushes are now correct, but the resistance between the two brush wires indicate a short somewhere... Am I on the right track? I can't get the left side cover off till tomorrow when my brother brings his grinder. Someone welded the shifter to the shift rod... Link to comment Share on other sites More sharing options...

I assume that you have a separated regulator and rectifier here is a diagram that may help. I belive the later electronic regulator/rectifiers are wired slightly different, so that is where the confusion comes in. did you check your voltage regulator?

bobin Posted August 21, 2006 Share Posted August 21, 2006 voltage regulator wr250f was replaced twice in two months does anyone have any ideas why and it blows all the bulbs. Link to comment Share on other sites More sharing options...
