1976 Tioga Sportsman Electrical Problem

[Tioga Sportsman]

I need some help, does anyone have any idea what to look for when the tank pump, and all level indicators quit working?

And does anybody have any wiring schematics they are willing to share by e-mail?

I made it all the way from Oregon to Texas in this beauty for a total of 2000 miles, she runs great and I haven't had any problems till the pump and level controllers quit working

Can't help you out directly but I would be looking for a blown fuse or a problem that is common to both circuits like an open ground wire or bad connections. Look for green corrosion around wire connections or frayed wires. Signs of hot spots like melted plastic around wire connectors to indicate loose connections. Good luck hopefully some one here will have a print or have knowledge of your particular Motor Home

since you lost the pump too, my guess is its not a ground. The pump grounds in another location. id look the coach side fuse block over and check for opens. just ground a test light and hit both sides of the fuse and where the wire exits as well. the old agc fuses corrode where they clamp in. the pump being on that circuit means its an easy fuse to blow as well.

I don't have a diagram of the coach side fuse block and don't know what goes to what, It was working intermittently but then quit again. I don't want to touch anything on the coach side fuse block unless I know what it goes to. I think a ground might have something to do with it because one of my overhead lights quit working too, took it down and checked for power and there was no power going to the light. The basic diagram seems to show all the lights, fart fan, pump and a couple of other things going to a common ground. I am still looking and want to thank you guys for the input.

Dave beat me to the punch. lol. The old agc. glass tube fuses corrode over time. especially on the end caps from condensation. I have twisted them around a few times and got them to work. The holders for them corrode also being an open fuse block connection. Get out the ole test light and see if current is passing thru.

You gotta be quick. I think I got this obsessive/compulsive thing goin' right now with GORV....but I'm trying to avoid too much interspection. you got a window though. I got hip replacement surgery tomorrow so all you other type A personality types got yer chance..at least till my Ipad shows up...;)

Have any one ever bought a manual from one of the ads on this site? Which one would be good to order from?

I will start checking what is connected but there are a few spade connections that are not even connected, I believe this was from the previous owner and for what reason I don't know. It would be nice just to have some sort of baseline as to where the spades go.

Thanks for the support.
