Title: Fuel gauge
Post by: Rob Molloy on March 29, 2013, 07:00:29 PM
Ok, so I have been woking on trying to get the fuel gauge in the Saratoga to work. I have been going through the tutorial on the main site. So far I have grounded the sending unit, which helped a little bit. The needle now goes up to 1/4 tank but then stops (car has a full tank).

I'm going to be checking the ground at the dash as well. Maybe I'll be able to get the dash lights working too! Any tips would be greatly appreciated. Thanks!!!

The temp gauge is electric. It used to work until I replaced the temp sensor. Need to try that one again.
 
I tried tapping the gauge and no change. The damn thing still is pretty stock for being 54 years old. Right now I think the main thing holding the tank in the car is the hitch. I'm looking at picking up a new tank and sending unit. Just to play it safe. If it doesn't work after that.....probably some hot rod gauges (http://www.moparfins.com/forum/smileys/smiley1.gif)

Can you ground the sending unit wire and then turn on the key?  Let's see if it goes all the way up.  If it does, then it coud be the grounding on the sending unit.  You just said something about the tank being loose.  Try grounding the tank first

it's not so much loose, as it seems to be drooping a bit. The straps are holding, but it's resting on the tow hitch. I'll try and get a pic of that one in a bit.
I did just go through and add the ground to the sending unit, as it wasn't grounded before. That's what got the gauge from nothing to quarter tank.

Remember that's a side fill tank.  I couldn't find one for my Sara

I haven't seen the tank out of the car. Is this one that would work?

That looks right.  And it looks like the fill is on the side
