starter solenoid

[Jim13]

Recently when I tried to start the coach it just clicked and after a few times turning the key off and on it stated. I thought it was the starter solenoid but I'm not sure because it looks like there is some type of fuse between the 2 terminals with the lower voltage wires. I worked on big rigs years ago and never saw this why is there a fuse on the solenoid?

Fuse may go to another circuit. Check battery voltage then cable connections before getting into the specific circuits. Most starter problems (by a long shot) are batteries or cables.

We were at a rally and one guy thought he had an inverter going bad. Opened his battery compartment and it looked like a copper sulfate factory- blue/green corrosion on many battery connections and paint peeling from nearby frame members. Took a voltmeter and with black on a battery ground post the red probe registered voltage all over the tops of batteries. On the frame in one spot where the paint had peeled, 4.5V!!!
Needless to say, his inverter was fine. He needed some maintenance on batteries and cables.
