Hello, im new here mostly because ive been able to handle my own problems. I just bought a 350 rancher from a friend and the bike didnt charge. Knowing what i know i pulled the voltage regulator off and it was shot! The slot the red wire goes in was broken off so i thought well thats my problem. That didnt fix anything. i can ohm out the yellow wires from the stator and they come back good. Have good ground from green wire. The red wire in the plug looks like it may not be making contact! If i jump the bike off or charge the battery the bike runs fine but still no charge. HELP!!
03 rancher 350fm wont charge battery

well the battery is dead now but it will take a charge but not from the bike. I have not checked the voltage from the stator. Ive seen where it is supposed to be anywhere from 30 to 100 VAC. Is this correct? if so i will check it when i get home. Thanks

re-check your stator..this is what charges the battery from the start..then it goes to your reg/rec..this converts it to dc voltage..your stator puts out ac voltage first..then goes to your reg/rec..if either one of these is bad..your battery will never charge.

Do the following tests. If the charging voltage test shows that it's not charging, do the stator (alternator charging coil) test. If the stator tests good, do the regulator/rectifier wiring harness test. If the the wiring harness test shows good, then the regulator/rectifier is probably the issue.
