Solenoid question

Couple questions. I was mucking about in the engine bay cleaning up some wiring and I found when I took the solenoid off the fender all four posts were hot. when it's grounded I get nothing. Is that normal? I also found that the bypass wire on the Solenoid has a constant 0.01volts, key on or off. I thought it was only active to boost the starter.

What is your reading @ "hot"? The solenoid requires fender contact (ground) for switching. There may be some residual voltage but if it clicks, starts and disengages run it.

I rechecked the solenoid and everything checks out . Jeep starts/runs fine. Maybe I was grounding out the solenoid somehow. One of those mysterious Jeep things!

Jeep was dead again 10.4 volts after seeming to be fine for a couple of weeks. When I put key into start/Hot position I got 10.4v. As an experiment I disconnected the red/white wire that gives full voltage when starting and get 0.04 volts with the key off. I believe this wire is spliced into the coil? Next I'll check to see if I have current leaking thru the alternator and pull the ignition switch and tumbler. The alternator has been replaced once butthe ignition switch/tumbler is original and could be leaking volts. Any other areas I should check?
