Ignition switch - accessory power

When I place my ignition switch is in the ignition position everything has power (radio, leveling system, etc.). When in the accessory position I have no power to anything. With no schematic I am having trouble troubleshooting the problem. Any suggestions?

Might be that you need a new switch, or it could be a wire or connection on the old one is loose.

Unfortunately the switch checks out okay. I removed it and it functions properly. The connections on the back are all good. One question I have is what should be on powered in accessory position and what not. I have wondered if the ignition and accessory wires could be switched. I am leary of switching them since they are so tight that I am afraid of ruining something if I remove the contact.

On my coach the ignition switch is prescribed by the chassis manufacturer, Gillig, and their manual has electrical schematics that show the connections to the switches. Basically accessories are just that - radios, GPS, 12v power to your controls like steps, fans, interior lights, and the ignition power to the main solenoid is the only difference. In the run poisition everything is connected while in ACC only the ignition power is missing. Check with Spartan they should be able to help. As for the tight connections the fact they are secure does not mean they are not corroded and not making proper contact. Loosening and re-tightening is a very reasonable procedure when chasing such problems. I found wires broken inside the connector plastic connector when it looked fine.

Today I removed the contact block from the rear of the switch. I then connected a wire directly from the power to the accessory wire and nothing powered up. I then jumped between the power and ignition positions and everything powered up. Apparently I am going to have to do some rewiring to get accessory stuff on the accessory wire, fun, fun, fun!
I have contacted Spartan and am awaiting their reply.

Before you start re-wiring be aware the switch does not usually pass full current to the coach, it controls relays that do the actual switching. On mine the relays are in the front outside electrical panel below the driver window. You should be able to find the relays that apply power and possibly fix the apparently bad relay. Since it once worked, it is unlikely a wire is the problem, unless it is a ground.

What has me confused is that in the ignition position everything works, including accessories. In the accessory position nothing works even though power is available for the accessories. That is why I think someone maybe has wired everything to the ignition side.

I do have a question though. The large round relay in the electronics bay serves what purpose? What power does it control? Could it be the accessories? I intend to study the layout of the bay and see if something is wired incorrectly as soon as I feel confident as to what is correct to begin with.

Lance, if it will make you feel better I also own a 93 Regency. I had to replace the ignition switch last year and when I pulled the dash there was NO wire attached to the accessory post on the ignition switch. I put the new switch in the same manner. Wires are attached to only three of the four terminals.

On my 89 Regal, the ignition switch accessory position originally did nothing, and I have over time moved some of the ignition controlled accessories to be powered by the house batteries for my own convenience.

What kicked this all off for me was reading the instructions for the HWH leveling system. It says to use the system in either the accessory or run position. Well, there is no power in the accessory position so I was checking and noticed there was nothing powered by it. I would imagine that for it to function I would need to install another relay for it to control all that I will most likely relocate.

That's about it with ours as well. Even the old stereo/cassette player is powered all the time. Don't think anything else is however, that I can remember; except the levelers. The engine is supposed to be off and the air dumped, then you power up the leveling system by turning the key to the acc. position.
Do your leveler system NOT get powered from the acc. key position?

My leveling system is not powered by the accessory position, nothing is. That brings to mind the question; where is the wire going to that is attached to the accessory terminal on the switch?

I also have some questions about the electrical schematic. The document I attached shows the data I obtained from the electronics bay on my Barth.
Why do only some wires have numbers?
What are CB1-6 and where are they? They aren't in the bay.
What do the following mean:
HDLP (taillights and power)
Aux Start
ING Reg
Neutral Safe
Inst LAMO
Cool Light
Drk Warn
Cond Re.

I hope someone can help.
