The Stovebolt Site Forums The Shop Area The Electrical Bay Hot Battery Cable and No Crank

I have done all that Carl & John suggest with my 6v 1954 Suburban.

I also use heavy cables - 00 Gauge (2/0 AWG)
I also use 00 ground straps (everywhere).
Optima 6v RedTop high-performance AGM battery (12+ years old)

Clean connection points for ground straps and use a conductive antioxidant grease at connections points.

If the truck has been sitting a long time, I might have to prime the carburetor and then use the choke.

Starts first-time every time.
