Ladies and Gentlemen:

Envision the following, a wire begins at the propane tank on the gage and runs to a switch located on the steering column mount. From this switch a wire runs through the firewall Chevy plug to a white wire that connects to absolutely nothing. I think the wire may have connected to +12v but I am not sure.

So why is there a switch in line to a wire running to my propane gage? What does this do and how to I hook it up.

Next question:

Does anyone have a pinout or schematic for the Chevy Instrument panel? Oh please, oh please.


Help and thank you:

Timothy

" a wire begins at the propane tank on the gage"...
Does the gage work? If not, the wire is probably a 12v feed.

My guess parallels your guess and certainly experimental research is not to be discounted however I am concerned about the unintended developmental consequences of pumping 12 volts into the two foot diameter three foot long BOMB under the back of my coach. You will note there is no fuse in the circuit.

The tank is (well almost) empty and the gage shows empty but I do not know what the default for the gage is.

Apologies: Re-reading my post I realize how far off it is; glad you're thinking, because I surely was not.

Hey thanks for the thoughts, I was attempting a little Mel Brooks over the top humor in my response. Think Young Fraunkensteen "So your are telling me I put an abnormal brain into six foot tall three hundred pound GORILLA?!" I hope you read my response with a smile.

The electrical stuff is going to take a while and your suggestions are always welcome.

Hello Timothy and Lana,

Yes, we have the GM 1973 motorhome wiring diagram. I can scan it...would you like me to send it to you?

Also on the propane tank, we think that's the sender for the propane tank's level sensor, which is in the gauge, not in the tank.

OldHouse:

Yes please, at this point I am interested in the pinout for the instrument panel. Can you scan it and email the scan?

The rest of the motor home is going to take a while. So no rush on the rest of the wires.

The wire does run from the gage but there is no remote display I can see. The wire goes to the bottom of the gage, I have not tested to see if the post is isolated from ground.

Hi Timothy and Lana,

I sent the wiring diagram to your email. Hope it helps!

I don't know how to insert photos or files into my replies to this forum. Dave, any suggestions???

Oldhouse:

The drawing are very helpful.

Thank you for your kind support.

Timothy

I don't know what email program you are using but I am sure that you must be using Outlook or Outlook Express since you have Road Runner. Just drag and drop you photo into the email. If you drag a file like a .jpg it will automatically put it in the attachments file or when you are in the screen to compose your email; see at the top where it says insert. Do that... Or you can send any image to an email recipient by just right clicking and where it says "Send to" just choose email recipient..

Thanks Dave! We'll try that when we're brave enough to post the "before" pictures of the Barth!
