Ever since I have had my coach, if I shut the engine off after I have been driving a few minutes it will crank very slowly. If I hit the boost switch the engine cranks STRONG right away and usually starts almost instantly.

Several years ago I researched this and suspected it was a ground problem. I think there were some PO modifications (well I know there were some as I have a 455 in a 1978!) Anyway I initially had only one cable from the engine battery and it was going to the engine.

So I purchased a battery with post and side terminals and had a cable made to go from the neg side post terminal to the frame. Unfortunately the problem persisted. I have been just living with it, but I have decided I would like to fix it. Maybe I did something wrong when adding the 2nd ground cable, Or maybe it is something else.

I do own a good DMM and am reasonably competent using it, but I am not sure what I need to check to determine why this hot start issue is still happening.

Any ideas?
