It doesn't start or shutdown with one push of the button,
I think all my problems are caused by voltage spikes on the computer bus
Had it into two dealers, I think the computer voltage should be regulated below 11 volts to prevent spikes
as the alternator/battery bus jumps all over the place from 12 to 15.5 But I can't get them to provide me
with test results or requirements.
What makes this problem better or worse?
Random but I think it is happening because I'm doing other things at the same time seatbelt etc.
