I drove my 1948 Ford V8 about 20 miles.I parked it for maybe 5 hours.When I went to start it,it acted like the battery was low.I checked the cables and the cable going to the starter cylinoid was very hot.Hot enough to burn my skin.The cables were tight,so I tried to start the engine again,it started like nothing was wrong.This has happened twice in the last month. All help would be appreciated,tanks John Lubinski

Do you have good heavy cables on it, and are all connections clean and tight? I would check out the entire electrical circuits with a Multi Meter until you find where you have a short or cross connection. "Sumpin ain't right"

Starters draw a very large amount of current, usually several hundred amps. As Lawson points out, any high resistance due to poor connections is one common problem, and another is a badly worn starter motor which allows the armature to drag on the pole shoes. The starter may turn easily until power is applied, then the very strong magnetic field pulls ths armature toward the shoes until it can't turn. This can, in turn, "drop" the load across the solenoid contacts, which will burn them up quickly. Once they are burned, it is a sure bet the solenoid will fail quickly.

Heat is generated by resistance. there is a bad connection in the cable where it connects to the battery end, solenoid end, broken strands, etc. 6 v systems need heavy cables. 12v cables generally aren't heavy enough.

If the cable from the battery to the solenoid gets hot, it is either undersized or has corrosion creating resistance. The cables can corrode under the insulation or at the connection and it will only be visible with a good inspection. If one cable is getting hot, I would replace them all, battery to solenoid, battery to ground, solenoid to starter and body to engine ground. Tom

I agree with TomO. This happened to me, the braided ground strap corroded at the battery terminal, and the damage was not even visible. It was so bad that it stalled me while driving. It had no continuity until I wiggled it! Having no spare at the time, I limped home with a bungee cord pulling the strap to one side. Alan
