Solenoid for the ignition switch

[mrbill1951]

I've been looking for the solenoid for the ignition switch but haven't located it. 

Does anyone happen to know where it is on a 99 Diplomat?

Thanks

Mine is in the front fuse box that is located in the front, drivers side, pretty much right under the drivers window.  May some Dip owners can help you more specifically for your coach.

I have a 09 HR and mine is in the battery compartment.

On our 2000 Monaco Diplomat the relay is located in passenger side rear compartment. It is behind a black plastic panel held in by 12 or 13 screws. Panel is located above inverter/charger. Our Diplomat was built at the HR factory, so might be different if your rig was built in Oregon. 

Image is defective relay from our rig. And mounting area of relay with cover removed.

Bingo!  Found them.  Thanks Pat C

Next question

How do I determine which one is for the ignition?

Here's a picture of the setup.  Unfortunately I can not remove the covering all the way at this point since they decided to run a ground wire through the plastic cover.  I need to figure our where it's attached or cut it and put a wire nut on it.

I'd just slit the plastic and slip it off that ground wire.

Put a meter or a 12v test light between the small trigger wire on each relay and ground, and have someone switch the ignition switch on and off.

That makes sense.

Thanks

I think I'll just replace it, since it is a intermittent issue.

I can only find 120-150851 part number vs. 120-105851-6.  Do you know if there is any difference?

Thanks

Here is Rodgers White https://www.supplyhouse.com/White-Rodgers-120-105851-Solenoid-w-Normally-Open-Continuous-Contact-Rating-100-Amps-12-VDC-Grounded-Coil. I'd call https://www.supplyhouse.com/White-Rodgers at 888-757-4774 and inquire about difference. The above link and Amazon site both parts as listed. 

Good idea to swap now.

Thanks Pat

Sorry I picked the wrong name for that question

I think I'll replace the solenoid and the ignition since they are both relativity inexpensive vs having a shop troubleshoot and correct.  I may still wind up there but it's worth a shot.

Just returned from a 500 mile trip without any issues with the coach dying. I replaced the  ignition switch, ignition solenoid and fuses.  Don't know for sure what the issue was, but one of these items fixed it and they were cheap.

Thanks for everyone's input and advise.
