Ok, sorry for the delay. Over Thanksgiving weekend, with the aid of my brother-in-law, the new cables were installed. MUCH better on the ground fault problem. I also got to move the power cables to the right-side of the car – away from the communication cables.
So I found a VERY cheap way to solve the GFCI tripping problem – a $0.25 “cheater” plug. Yeah, it’s not elegant, but it solves the problem of the charger tripping the GFCI all the time. I’ll keep looking into why the charger behaves the way it does.
I’ll post pix later of the new cables and the new crimper.
