Hi. I have a 1970 F100. I am wondering what would cause the voltage at the hot-when-on lugs in the fuse panel to be less than 12 volts. I have 12.6 at the battery and 10.2 at those lugs. This is with the truck off. I had an HEI dizzy wired to one of the lugs, it had 12 volts when I installed the dizzy last August. Now, just this week it won't start, and I only have the 10 volts at those lugs. Any suggestions on where to start looking?
Thanks!
Remove the fuse block and check the connections on the back. Those often get corroded. Also wrap some steel wool around a screwdriver tip and scrub the the fuse contact points.
