battery eliminator capacitor problems

[650ccdeathtrap]

I'm newto this forum thing so please be patient and here goes. I have a 76 xs and I am running it with a tc bros battery eliminator capacitor and it ran great for about a week and then it died because my capacitor and coul was fried. I then replaced the parts and it ran well for another week and then the same thing. Any suggestions?

to me it sounds like a wiring issue.

Stock charging system? Inline fuses? I'd hafta see your wiring.

I would have to get a pic in the morning but I am using an aftermarket pma with a 15 amp inline fuse to the capacitor, as well as a fuse box for accessoties which is mounted to the rear fender and the bike is lowered so it does bottom out occasionally

Me too but I've looked it over several times and appears fine and the bike runs fine for a while then burns up. Could it possibly be that the capacitor is wired backwards?

Did you wire the bike yourself? Could you post a picture of the diagram you used? Might be the easiest way to show everyone how you have it set up currently.

if the cap were wired backwards,i dont think it would run at all

Yeah, I'd def need to see a wiring diagram or picture of sorts. Break it down in sections. Start at PMA with a DMM and check towards the capacitor. Capacitors store energy, so maybe some kinda excessive surge? Hard to tell. I've wired two kick start only in the last year. One I had to use a small .8 amh battery to run lights. My memory sucks so if hafta go look to see how I wired them.

Start here, how closely does this match the way you have it wired?

It is almost exact except for a neutral light and the kill switch is run through the head light so I can have a start up sequence but I did not wire it. There are 20 amp fuses for the headlight and taillight and I'm pretty sure no fuse to coil. I will have to go check,it is at the shop right now

 

[jamesgs4]

how did you test the cap and coil for failure? are they melted down?
