Working on a '51 ****** and have starter problems. Using a Ford silenoid for the electric starter. Working the 3rd silenoid so far. 12V go in, but only 8V come out and go to the starter. I'm assuming the silenoid is bad but any ideas on what might cause 3 of them to go bad? The power wire comes off the batt, goes through a 175AMP fuse then to the silenoid. Wire from other post on the silenoid to the starter. Of course the wire from the starter switch to one of two small posts on the silenoid.
