1984 310 Limited MH   P30 Chassis

Hello,

I'm writing to you from Bahia Kino (Kino Bay), Sonora, Mexico.  It was a bit of a struggle getting here.  I have copied  a recap from a thread on the Airforums:
(http://www.airforums.com/forums/f15...8329.html)

I'm hoping for some more suggestions and/or a wiring diagram of how the rig is supposed to be wired.

Since mine is a diesel, I can't be much help.  What I will do is bump you back to the top and maybe Steve Or Andre will pick it up.

Hmnmm. I know mine had a second relay mounted on the alternator bracket. It was prone to vibration and frequent failure. It eventually replaced the GM style with a Ford stlye and relocated it to the frame inside the engine compartment.

Steven, That relay is the "S-LEAD" which goes to the starter, I've changed mine out and the ford relay might be a good way to go.

Hummmm, Mine has been on the alt. bracket and still works and never had an issue with it. I don't know how old but didn't look new when I bought the coach.. I have heard that they change to the Ford Solenoid. If mine goes south it will be changed to the Ford. Isn't it pretty bad when you have a Chevy and have to use Ford parts to keep them running??

Here's the update.  I couldn't find the source of my dead ignition and the amount of work I can do in the RV Park we're staying in is limited.  So, I decided to take it to the Chevy dealer in Hermosillo.  Drove in on Monday (hour and a half) to locate the dealership and make an appointment.  Made an appointment for 8 AM Wednesday.  Left the RV Park at 7 AM heading for the appointment.   It was cool, so I turned on the dash heater, in a few minutes it had warmed up nicely and suddenly my oil pressure light came on and the gauge dropped to zero.  Shut down the engine and stopped.  I had added oil before we left so I knew I had oil.  I then remembered an occasion on which the rig had been parked facing the sun with the curtains open in the summer, when I got in (it was 130 degrees inside) and started it, the oil light came on and the gauge read zero.  When I returned after the rig had been in the shade for a while, the engine started and the oil pressure read normal.:huh: :huh:

So, I started the engine, listened carefully, checked engine and oil temperatures, everything seemed normal. So we headed down the road.  I shut down the heater and switched to vented air on the cool setting, after a while the oil light went out and the pressure gauge came up to normal. :confused:

So we made it to the appointment where I showed them that I had to hot wire the rig to get it to run and I showed them where someone had run a wire from the distributor battery terminal directly to the rear fuel pump.  I asked them to clean it all up and make it right.  I gave them copies of the diagrams Tom sent me, which they used as models of how this were supposed to be.

We waited all day and finally around 6:30 PM they called me over.  The showed me where they had done a real nice job of fixing up the wiring and installing a relay to power the fuel pump.  BUT they say, the ignition switch is failing intermittently and that is the source of my ignition problem,  and OBTW, the fuel  between the tank and the rear pump is cracked and may be leaking.  They tell me I really should get that fixed but they can't do it until tomorrow. :sad: :sad:  Also, GM parts distribution is shut down for Christmas and they wouldn't be able to order the part until after New Years.

Since Marian and Luc are homeless in the RV Park, I decide that I have to head home.  Between the engine stalling and stopping for repairs (hot wired it again, messing up the nice repair they had made to my last hack job) it took an HOUR to cover the first 2 miles of the return :ohmy: :ohmy: .

And, BTW, my toad brake is totally inoperative. We made it back to the park about 9:15 to the great relief of the wives.

After a drink to unwind and some dinner, went to bed.  Woke at 4 AM ans was sick as a dog (details skipped) :yuk: .  Turns out, Dave, the fellow who went with me, was also sick all night.  We both incapacitated today.  We ate lunch in an upscale bar/night spot near the Chevy dealer and must have gotten food poisoning there since neither of the wives are feeling bad.

Any suggestions about how I should proceed?

Clearly, I need to fix or have the fuel line fixed.

Should I just leave the engine hot wired?  Or, try to get an after market switch?

Does anyone know, or have the ability to look up, a part number or what else this switch might fit?

Should I delve into the oil pressure indicators or not worry about it until I get home?
