Re: Dreaded Click and NO START Cause/Photo of Relay

Thank you. I just experienced the exact same symptom. Click no start.
I first cleaned my battery terminals and that improved my results. But a few days later it recurred and nothing changed when the coach Boost switch was engaged. Click but no starter spin or start.
I went to
And searched for click no start and found several troubleshooting threads.
One suggestion was to take a heavy battery jump start cable from the battery ground to heavy metal on the engine. (short ground battery terminal to engine)
I tried that and my 06 coach (56k miles) started no problem.
I then removed a braided copper ground strap (drivers side just below oil filter cap) and found the chassis side bolt not fully tight. It wasn't loose but it wasn't tight either. Used sand paper (80 grit) to clean both surfaces and wire wheels to clean the bolt holes on the braided cable. Sprayed brake cleaner on all the exposed surfaces and everything was fine problem solved.
I'm confident that the issue in my case was poor engine to chassis ground connection based on the fact that the jumper cable shorting eliminated the click no start issue.
New braided cable on way ($12 eBay) to be installed when I return from current trip.
I also removed and cleaned the short negative cable that connects to firewall for good measure.
2 days and 15-20 starts later it starts every time first crank so I am a happy camper.
Not sure what I'll do with the Amazon bosch $180 new starter that I purchased but I guess it is a reasonable spare to carry for now.
Best regards and thanks again for sharing your learning
