Unless you've designed switches, you probably don't know much about closure
rate and contact pressure to minimize arc-over, either. Slow or soft
closure allows momentary arcing which is a great way to weld contacts.
Hard closure also helps overcome the oxidation layer that forms almost
instantly on most pure metals like the copper used in those starter relays.
All that is an effect of high resistance restricting the current through
the solenoid coil which gives you a weak closure.

Re: 81 CJ 258 starting problem
But a low amperage will melt a starter and often the cables and solenoid
going it, usually not allowing us to shut off the starting motor until the
battery is completely dead.

Re: 81 CJ 258 starting problem
I read the rest of the replies, mostly argueing about resistence, anyway
Mike I cleaned all connections on bat. solinoid, and alt. only one I didn't
clean was one down at starter, and starter and bat cables are about a year
old.
Bill mentioned at some point bat. was disconnected while running, that
didn't happen, but when I thought the bat. was dead the other day I used my
battery charger which has a setting for 70 amps to start a vehicle, which I
used and it arced when disconncting it. I replaced everything on engine when
I put a rebuilt in 1 1/2 years ago, all but alt. Am I now ready for that?

Re: 81 CJ 258 starting problem
You need to pull the starter.
You might be able to fix the trouble and put the starter back in, or you
might need to buy a new one. In any case, my money is on a starter problem.
