I have two atv's one is a 4x4 and the other a 2 wheel drive. And to my surprise they have different voltage regulators. The 2 wheel drive is giving trouble and I can't find the chart for testing the resistance ect. Coming out of it is 3 black wires in one plug and 4 wires in the other 2 blk/r and 2 blk/w. Can any one help me with how to check this out.

Thanks
PS. First time on the site and can't believe how easy it was to join and navigate

 

Just a follow up to my post. I now know its model number. Rectifier oem part number 3530 059. Does anyone have the resistance measurements for this?

Thanks
