As stated in Clifford's post #9 these are the switches and relays that must close on most coaches to make the starter run..... 1) Ignition switch, 2) Neutral safety sw, 3) Starter Relay, 4) starter Solenoid. Having a DVM and knowing how to use it, makes quick work of this. An RV owner without a DVM, and knowledge to use it, must have a FAT wallet ($$$) to survive. Rook

Here are two photos. One shows the new relay and the other, thanks to another contributor on the forum, shows where it is mounted on the frame rail.

If applicable to your coach, I hope this helps.

Let us know.....thanks.
Thanks for the pics. As soon as my back pain calms down, I ll crawl under there and check it oot!

Thanks,eh?

As said there are some pre-relay and pre-solenoids along with a neutral and maybe a lockout relay, before the main starter solenoid and even if you're sure that you're hearing the main solenoid clicking, it could still not be pulling all the way in.
The most likely culprit is some dirty and/or loose connections along the way, stopping or limiting current flow. Cranking over after some tries, with the heat building up, is sort of an indication of this phenomenon.
My cure is to install some emergency circuitry for by-passing all this paraphernalia.
I have one large and one smaller momentary push button mounted in a plastic residential box and hidden back in the last bay, next to the engine on the passenger side.
The large heavy duty button wires across the secondary solenoid contacts and in essence, puts battery voltage directly on the starter's main solenoid, so if that doesn't work in a pinch, you might as well, replace the starter.
The smaller button puts voltage on the coil of this secondary solenoid and if it doesn't want to work, then replace this said solenoid. If it always works, then you need to start looking up range. Least ways, you can get it started and look into it later. Beats crawling around in a rainstorm and/or traffic, or calling for a mobile mechanic and/or a tow.
Funny thing and with a lot of these add on backup systems, once they're installed, the problem doesn't resurface. This tells me that the loosening, removing and otherwise with installing the extra wiring, cleaned up the connections. Now, that mine is done, it's staying in there and like the idea of having it, for a just in case and some peace of mind. Now, if all else fails, I just turn on the ignition and walk back to push one of these buttons. Being first sure that it's in neutral and the parking brake is on, of course.

I have the same problem as stated by the OP. I found 2 of the solenoids that you posted a picture of. I have a 1999 Mountain Aire 40' with a 330 cummins. Is that the solenoid I should be looking for. I have been looking for a ford style solenoid
Thx Brian

Brian,

What is depicted in the photo is a White Rodgers Relay.

Freightliner refers to it as a "start relief relay". When energized it turns on/off switch contacts momentarily so power can be directed to the starter.

The solenoid you might be referring to should be mounted adjacent to your starter. Although both provide action when energized, there are subtle differences between a solenoid and relay.

Maybe someone with a Mountain Aire has the starting schematic for an 03 they would be willing to share
that starts at the ignition and
ends at the starter......anyone?

All this is usually a chassis thing, so could very well be the same for many brands of coaches. Mine is a Spartan and one who will send you anything you want in the line of diagrams and mechanical exploded views. Most sure Freightliner will do the same, as may others.
