No power to Acc on my 1994 Holiday Rambler

[MyFirstRV]

Has anyone out there had an issue with loss of power to the accessory position on the ignition switch? I replaced the switch and still no power? It is a 1994 Holiday Rambler Endeavor Le diesel pusher. I was hoping someone could supply me with a copy of the wiring diagram for that model or if anyone has had a similar issue and was able to correct it.

Sorry I can't help with a diagram, I'll ask a question though.
When you purchased the replacement switch , was it the type of switch used in mid 1970's Chevy P/U trucks?

What chassis is you HR built on? Perhaps I can help with a wiring diagram.

It is an Oshkosh chassis and has a ford column switch. I suspect a bad relay somewhere in the system. I have been trying to isolate the problem but haven't had much luck so far. Everything works fine with switch in the run position. The problem comes when you try to deploy the leveling jacks. In the run position the warning lights and buzzer goes off and it is very annoying! I am good with diagrams if one can be found. If not any help will be very appreciated. I also am having to replace the holding tank board and senors and have purchased the I-Series system.

Sorry, I can't help you with a wiring diagram.

On my chassis (Spartan Mountain Master) the ignition switch feeds two solenoids in addition to the start solenoid. One is located in the front panel and the other in the back panel all activities requiring ignition in accessory or run position are fed from one of these two solenoids.

Each solenoid has only one conductor between the ignition switch and the solenoid coil.

Bottom line: If a system works in the run position but not in the accessory position, the problem must be in the ignition switch.

Hope this is of some help.
