Wondering if wiring schematics are available for my 81FC35. It would help me to figure our several problems I have: 1. No blinkers on right side, but the right side works on the flasher. I have blinking power at the right solenoid above driver, but not at the junction terminal on the right side swing out door. Somewhere in between. 2. Previous owner put in manuel valves to open engine heat to the w.h. and chassis heat. Is the solenoid valve inline under the cabinet in the Rear bath right before the bath chassis heat? 3. When I turn the ignition to the on position, with gen battery disconnected, I still have power to the gen starter, it starts cranking. Not sure how to disconnect the two remote switches from the gen compartment to see if i might have bad rocker switches inside that are stuck. Any help would be greatly apreciated. This is my second motorhome restoration, just finished a 1972 Cortez, had lots of fun last month in Rocky Point. Saw the bird in Page on the way home, had to have it. I still have my 38' Monaco, but hope to get rid of it and replace it with the bird for our longer road trips. It takes a while just to get far enough south from here in Bigfork, Mt. Thanks, Jim 1981FC35RB

Jim,

I had a 1980 so maybe this will be close…

Blinkers: They were both (L and R) in the overhead, there may have been a third for hazard. Suspect the barrel connectors at the load centers for poor connection. Relay could be bad as well. One of the large relays in the overhead is for the Air Conditioning.

Winter/Summer Heat/Front Heat: Look for three water shut off valves under the coach to enable coolant flow. There are also sporlan valves under the bed (side bath), for the summer or winter loop. And a sporlan vavle up front behind the bumper for the front heat. Sporlan valve are normally closed, DC powered fluid control valves that you control at the dash. Front heat, summer heat, winter heat,…

Genset: There is a momentary toggle auxiliary battery switch on the dash that activates a relay to power the generator off the coach batteries as a starting aide. Look under the step well for this (bad relay or maybe bypassed by old owner). Also, on my genset the toggle switch in the genset compartment would sometime stick in the start position; in this compartment a harness ran to the start/stop switch that was from the coach. If yours is a diesel, this may be different. I also had an issue where one of the remote start/stop switches was mounted in a compartment door w/a loose connection. If you opened that door, the generator would run like crap… took a while to notice the relationship.

Those barrel connectors I mentioned should not get hot to the touch. If they do you need to address this as equipment down the line will not be getting the power they need. Try a little deox-it on them, sold at radio shack. Pretty effective stuff, spendy, but effective.
