We're working on our front dome light circuits and can't figure out why the switches are double throw. Switched up, the lights come on, center off, but what is the switched down position for. Checked the operating manual and can't find it. We thought maybe it was part of the galley light system but that switch by the entry door only lights up the fixture above the sink.

So, we had to check in with the brains on the forum. Any help is much appreciated.

By the way, Matt Colie helped us with our fuel supply system. Just got the coach back from the shop, cleaned and reconditioned gas tanks (tank renu) and new fuel lines to the solenoid. We had a bad and cracked generator fuel line that leaked. Once fixed and the rest just for peace of mind we're back in business. Still have fuel gauge problems but the sending units are OK so we'll track that down when we get more time. Right now only the auxiliary part of the gauge works, no reading for the main tank. But we've had occasional main tank reading but not recently.

We're off this weekend for our first trip over 100 miles to Ludington, MI to spend Friday and Saturday night at the state park there.

Our speedometer bounces around a little too so we're keeping an eye on it. We're hoping it just needs to be exercised. We peeked at the cable behind the dash and it doesn't seem to come apart so we could lubricate it. Anyone know if in fact it does come off there so we could lubricate it some? Looks OEM. We have a 1977 Kingsley, 403 with a brand new 3.70 final drive with limited slip. Hope we make it there and back in one piece.

Thanks all!

The dome switch on my 77 works this way... Up they come on, center off,
down they will either light by turning the headlamp switch to the left or
if the door is opened. The door switch on mine no longer works well
enough for it to light them however.

OK, thanks. I tried opening the door and that didn't turn them on. I wondered if that's what was supposed to happen. But the door switch works as it lights up the dash warning that the door is open. Something not quite right. We'll work on it.

Thanks!

Hi

I would guess it works like some of the new cars,
Always ON-OFF-ON when door is open

Try turning the head light dash dimmer and see if that activates them.

So the lights will come on when the door opens.

Mickey,

There is a connection for the two sending units near the selector valve. That has often been a problem for me. Even if it isn't, a meter can tell you if the problem is forward in the dash or over the tank (you hope not).

Which State Park ?

The speedo cable has a push down arm to release it from the head. That is a good place to lube the upper cable if you still have the OE cruise. If you do, also lube the cable that goes down to the governor from there.

Matt

My transmode has one position off, one position on, and one position courtesy lights - on when the door is open. They could also be wired to come on when the switch is rotated to the brightest and a click beyond. Dunno if mine come on then or not.
