2000 King Quad 300 burning up regulator/rectifiers

[dvdclarksn]

I recently posted pics of a burned up stock regulator/rectifier on a 2000 Suzuki King Quad 300. It lasted about 14 yrs. and the group advised replacing it. After doing this and replacing the battery it started having the same symptoms before the other unit died. The engine would run very rough unless the headlight was switched on. Then while riding one day the engine died completely. Any ideas as to what might be killing this particular part. The part was not that hard to replace but runs about $95.00 and is a pain to access. Want to get this tested and repaired once and for all. Any suggestions are appreciated.

I think you have a short somewhere. Check wiring where they contact the frame first. Right side under the seat is where Ive insulation rubbed off and shorting to ground.

I have replaced the regulator/rectifier and now the main fuse randomly blows. No chaffed wiring or breaks anywhere. I am thinking disconnect all of the lights and see if the problem repeats to at least eliminate something. Any other ideas or similar issues/fixes from anyone? Thanks

I had the same problem on my 99 KQ. Two bad new voltage regulators in a row. High voltage output screws up the ignition module. Then I found a good used regulator and it worked and has been working ever since.

Where is the voltage regulator located on a 2000 king quad 300?

I have looked all over the place and cant find it i have a new used one to install but the previous owner removed it and i dont know where it goes
