1980 Chevy El Camino What is Going on ???

Hi there,

I would start with the simple things, check that the battery terminals are all clean and tight, check the terminal connections at the starter motor for a good contact and no corrosion, start here,

I had a simalar problem 1 time, It was the small wire that comes off of the battery cable terminal on the starter solenoid. Its what feeds power to the fuse box. Check and or replace a foot or two of that wire with a comperable size wire, I beleive it is 10 guage.
