correct, when the engine is hot ....or up to temp. ...and I shut off the coach.....I'm not getting the starter to engage, and I've yet to determine if I'm getting the correct voltage to the solenoid......this weekend I hope

can you tell me more, or share a link?

Tom, That was extremely helpful. I'll get cracking on this list.

The solenoid is attached to the starter ....if that is helpful. So...should I be checking voltage at the starter when trying to start?

There is a definite solid click that sounds to me like a bad solenoid, but with the starter being brand new (when this issue started) I did not think it could be a solenoid.....but I suppose the new starter could have a bad solenoid ???? The batteries are new and charged. It only gives me this problem when its hot....but not 100% of the time. Sometimes when its hot (having been driven for a while) it will start. But to be honest........I do not turn the coach off until I reach my destination. Rick, I do have the rear start switches and have tried to start the coach from the rear....so that I can see and hear what is happening. It is hard to say where the distinct SOLID click is coming from.....but it sure reminds me of all of the '60s Mustangs I've owned when the solenoid is bad. Being a new starter, and new batteries.....I simply thought it must be something other than the solenoid. I do I jump around the solenoid to see if the starter will crank? I remember how to do it on a mustang ...lol

Sure could use some help. I've got a problem with my 2004 Monaco Windsor that has a 400 ISL Cummins engine that have been dealing with for the last couple of years. It started happening after I replaced the starter. After I run the motorhome for a while maybe 100 miles sometimes just 10 miles……….. if I turn it off …..quite often it will not restart. The starter does not engage. All I get is a click….. obviously back in the engine compartment. I know this is not very much information. And again this did not start happening until I replaced a bad starter with a new starter. I believe the starter I replaced was original, and I know that the new starter that I installed was the correct starter for the 400 ISL. More details below. I can tell you a couple of things that I've done to try and fix this problem. I've replaced some relay switches that are back on the sidewall in the engine compartment. They are on the right hand side if you're looking at the engine. I can send you some pictures. The reason I replaced these relays…… is because that seemed to be the place I was hearing the click when the engine would not start. So I replaced the relays and their associated fuses. I thought that it solved my problem. (Because it doesn't always happen) …. But then the problem started happening again. In fact I don't think the problem ever went away. The only thing I know for sure is this problem started after I replaced a bad starter. Just so you know the starter I took out of the coach had its negative terminal wobbling around inside the housing….. That's how bad the old starter was. I had a mechanic install the new starter 2 years ago (That's how long I've been dealing with this problem). I know I got the correct starter for the 400 ISL Cummins….. But it did come with an extra part attached………. the mechanic said This part was not required, (so he took it off and did not use it when he installed the starter). The old starter did not have the extra part and so it seemed to me that the mechanic was probably right……. And who knows he probably was right and my current problem is unrelated. ….. However I still cannot for the life of me figure out what is giving me this issue. If I let the coach sit for many hours ……usually it ends up being overnight. The coach will fire right up. As I have been working on Coach in my garage with a suspension issue over the last couple of weeks……. I have started the coach dozens of times….. Without issue. Today I took it for 10 mile drive parked it back in the garage……. turned it off ……weighted 15 minutes…… went to start it and it would not engage……… just a click. Can anyone give me some insight?...... Or ask me some questions so that I can give you more information. I sure do appreciate the help. David
