leelee Posted March 15, 2013 Share Posted March 15, 2013 Where does the ground strap go? I have looked everywhere. I bolted another wire to it and ground it on the dash frame and still won't light the only thing working is the clock. Oh yeah, I looked for a answer and did not find it Quote Link to comment Share on other sites More sharing options...

I'm working on your speedo needle, instead of confusing you with a bunch of useless jargon or typing. Quote Link to comment Share on other sites More sharing options...
leelee Posted March 15, 2013 Author Share Posted March 15, 2013 Thank you Mo that helps a lot. Now about the gas gauge, It is at 3:00 so I checked some of the threads and found that it is probably a ground wire. I got back under the car and sanded where the wire goes and sanded the wire connector screw it back in still nothing. Quote Link to comment Share on other sites More sharing options...
LostnFound Posted March 15, 2013 Share Posted March 15, 2013 My fuel gauge stopped working last summer. Replacing the circuit board on the back of the cluster fixed it. Quote Link to comment Share on other sites More sharing options...

Hay caramba!~ Read this carefully.. it will help you understand it, instead of pulling your hair. Believe me you'll thank me later! Fuel Gauge Problem Diagnosis: "The Monte Carlo Engineer" This process can be applied to all recent GM cars except those with computerized gauges. 1) Locate the fuel sender feed wire near the fuel tank. You're looking for a single tan colored wire. With the tan wire disconnected at the fuel tank, the fuel gauge should read past full with the ignition on. Wait a few moments as some fuel gauges take a long time to respond. Touch the tan wire from the body to any convenient ground and the gauge should read empty. If not, you have a wiring problem or a bad gauge. 2) If the gauge responds correctly, the gauge and wiring are OK. Next use a multi-meter to measure resistance to ground of the sender wire connection on the top of the fuel sender or the tan wire from the top of the fuel tank. Measurements should track the fuel in tank. Full - 84-88 ohms Half - 40 ohms, give or take Empty - 0-2 ohms If this doesn't check, then sender or wiring on top of the tank is bad or the sender not adequately grounded. Senders are typically grounded by a black wire which is welded to the sender and attached to the body with a sheet metal screw. 3) If the sender checks OK but gauge and wiring don't, clean the connections, reconnect the sender wiring and separate the Fisher connector (located just outboard of the fuse block under the dash). The gauge should then read past full. Ground the tan wire in the dash side of the Fisher connector and the gauge should read empty. If not, you probably have a bad gauge or possibly a dash wiring problem. Go to Step 5. 4) If the gauge checks OK, then make the same resistance checks to the tan wire in the body side of the Fisher connector. If the readings are different than those at the sender, body wiring has a problem and requires detailed inspection. If they look OK, then the Fisher connector is probably dirty. 5) Clean and reconnect Fisher connector, pull the connector off the back of the gauge and make the same resistance checks to the tan wire. If they don't check, you have a dash wiring problem. If they check OK, your gauge is bad. Gauges can be bench-checked but this is best left to a specialist.

Mo's70MCs Posted March 15, 2013 Share Posted March 15, 2013 That does it Rod, I'm moving to the US...on your street! Now Larry that stuff is easily found and you know where, I'm sure I ain't got to school the "master of research". Quote Link to comment Share on other sites More sharing options...
LostnFound Posted March 15, 2013 Share Posted March 15, 2013 LOL....that's true Rod but electrical just isn't my thing. I've just never been able to wrap my head around it. I'd rather feed you beers and have you do it for me. Quote Link to comment Share on other sites More sharing options...
leelee Posted March 15, 2013 Author Share Posted March 15, 2013 OMG, you are wonderful. I love this. I looked in the search but did not find this. Did you find it in the archives? Anyway THANK YOU SO MUCH. I have a new circuit boaurd on it. I think once i get the gound right the lights should work. Quote Link to comment Share on other sites More sharing options...
stangeba Posted March 15, 2013 Share Posted March 15, 2013 Great write up. I copied it to a word doc and saved it. Now it will be interesting what the problem turns out to be! Bruce Quote Link to comment Share on other sites More sharing options...
leelee Posted March 22, 2013 Author Share Posted March 22, 2013 Got dash lightd Yaaaaa. Now on to the gas gauge and speed ometor Thanks again Mo. Any help is appreciated Quote Link to comment Share on other sites More sharing options...
leelee Posted March 23, 2013 Author Share Posted March 23, 2013 It was the ground, i did a quick ground and my speed ometore lite up. now once i get the sttrap connected i think they all will, on to the gas gauge and speed ometore Quote Link to comment Share on other sites More sharing options...
stangeba Posted March 23, 2013 Share Posted March 23, 2013 Bad ground strikes again! One of the first places to check. Quote Link to comment Share on other sites More sharing options...
