Kevin, I'm going to be the ASS here....WHY did your original EHC go bad? Any ideas on that?
I'm asking because if what caused your ORIGINAL EHC to burn out/fail was not fixed, just putting a new RIP kit/EHC/etc.. would not solve that problem, and from reading what you wrote, you followed directions and re-checked the plugs/wires....so, again, do you know why your original EHC went bad?
Also, I am unfamiliar with the RIP Kits, I'm still running original EHC's on two bikes....but, if a short somewhere on the bike made the original EHC fail, you need to find said Short.
Then again, it could be something much simpler.
