Just what I needed to troubleshoot my electrical stuff on my old '78.Re: Vintage RV upgradesCheck that the heat riser valve in the exhaust manifold is working properly. Replace the PCV valve. Make sure the dual fuel tank valve is working. If it has hydroboost brakes, check the fluid.Re: Issue fueling 1994 Jayco Eagle on E350 chassisCould be the gas station pump handle is causing the problem. EZ FILL NOZZLE KEY USE IT WITH 18" OF RUBBER WASHING MACHINE DRAIN HOSE. HOLD THE HANDLE WHILE FILLING. TRY TO FIND ONE AT A MOTORCYCLE SHOP. http://www.aerostich.com/e-z-fill-nozzle-key.htmlRe: Bizarre fueling situation. Issue #1 on trip.My motorhome is a 1978 Dodge and I have a 1973 Chevy C-10 pickup. Both have trouble filling the tanks. I use a 'EZ FILL NOZZLE KEY' with an 18" piece of rubber washing machine drain hose. Works ok but I have to hold the pump handle while filling. http://www.aerostich.com/e-z-fill-nozzle-key.htmlRe: How many of us are there? Owners of Dodge based RV's?How did you do on your cruise control project? I'd like to get mine working on my '78 but I have no knowledge about how a CC works. DRTDEVL wrote: OK, I'm back... Finally decided to look into the cruise control today after I welded new supports for my battery tray (rusting away). Right off the bat, I noticed its plumbed wrong. The cruise actuator is under the master cylinder on the firewall, and everything moves freely by hand, but it has 2 vacuum lines, and I know its not right. Both of them go to a little tin can on the firewall... and nothing else is plumbed to it. How does this hook up? I'm guessing the canister has a check valve in it (if not, I'll get a universal one), but where in the system is this routed? Why 2 vacuum lines to the actuator? Its a 1980 Winnebago Minnie Winnie on a 1979 chassis... what I thought was a CB300, but I found a sticker in the cabin that this little 20.5 foot unit is actually an MB400, probably because it was ordered with the 10,500 chassis. Re: headlight switch on 1978Got it done. I made a HOW-TO file. 1978 DODGE HEADLIGHT SWITCHheadlight switch on 1978Problem- gauge lights quit working, 1978 Dodge Class C. Has anyone replaced their headlight switch? I need to know which parts of the dash to remove to reach the switch. I have removed the panel under the steering column. Should I post this in a different section?Re: How many of us are there? Owners of Dodge based RV's?edit- Found the stupid fuse box in the stupid glove box on top of the stupid dash and I feel stupid, My '78 doesn't have a glove box. I did get 3 of my clearance lights working so the fuse must be ok. TreeSeeker wrote: My 79 Dodge's fuses for the chassis are in the glovebox. Re: How many of us are there? Owners of Dodge based RV's?Thank you. My valve seals seem to be good. The exhaust looks fine and my HC measured 52, allowable is 350.

Just passed our California Smog Test with excellent numbers so I'm pleased the old Thermoquad is still functioning ok. I'm enjoying fixing a few little problems on it. Got it to stop vaporlocking by wrapping and shielding the fuel line near the exhaust. Next project is replacing the clearance lights with LED units. Can someone tell me where the fuse box is usually located? The vehicle fuse box should be located in the same place as 1978 B100/200/300 vans, sometimes called Tradesman or Sportsman vans. IIRC, it was located under the dash on the left close to the driver's door on my '77 B200 van. There's probably a second set of 12 VDC fuses for the house/coach interior, usually near or on the power converter. Most have a third set of fuses or circuit breakers for 120 VAC shore power. These will usually look like a household fuse panel and are typically located inside the house/coach, very near where the shore power cord enters the motorhome. (Usually on the left -- driver's -- side amidship or towards the rear.) An aside -- if your engine starts using oil, it's probably due to disintegrating valve stem seals. This is common on older Dodge engines due to both wear and age. These can be replace without removing the heads ... if the mechanic knows what they're doing and has the right tools. If your engine does start using oil (or blowing blue exhaust), I strongly recommend replacing valve stem seals before considering a more expensive valve job. Re: How many of us are there?
