Fried my CDI box last weekend. I had just put a new regulator on. Hooked up the new one and found that the rectifier is overcharging. It’s 17-18volts at idle. I took the epoxy off the back of the rectifier and everything looks good. No burnt connections or anything. When I first put the rectifier on it charged 13-14 volts depending on rpms. Any way to fix this? I’m trying to ride this weekend lol

Aftermarket or oem unit? Alot of the aftermarket stuff is hit or miss affair.

Welcome from Colorado.
Sounds like you have more than one problem, or replaced the wrong part first.
Over charging?

Sorry bout that. It’s a grizzly 660 2005 model. Yeah it’s a cheap aftermarket regulator. I expected to see a problem in that unit to cause it to over charge but the diodes and solder joints look ok. Does anybody know if these are one or 3 phase rectifiers?

And that’s for welcoming me. I hate my first post to be asking for help. I’m an auto mechanic by trade so I’m familiar with tools and test procedures, just new to ATVS. I like to take stuff apart, open things up and fix it rather than replace it possible

Try reflowing the solder joints. From looking at the pictures only, it looks like some of those solder joints are bad.
