Well, battery tests low CCA, confirms bad battery 75% health 12.4V charge engine off. ALT is putting out 14.3V at idle, 15.1 @ 2000rpm. Not sure what you mean by EMI? Factory unmolested harness, seems all intact, however about the grounds... does the factory small ground on the chassis in front of the battery have a link in it? So seems that my factory ground cable on the battery does no grounding at all. Hence the other grounding that I have put in place. I would like to get my hands on an EVTM or factory manual... however I have neither, only a Haynes manual, which has some useful info but not specific to supercoupe and doesn't help much.
So now you mentioned grounds, I may just check into that factory battery ground... then check grounds to the EEC and signal to the DIS. Tach is working fine, but you got me onto something, this is good. I hope it's something simple. And new battery is in the mix tomorrow as well.
