Spent some time going over the gas gauge problems with the search function, just need to know I'm going in the right direction. Car is a '69 vert, factory in dash gauges, fuel gauge doesn't work, stays pegged at the 9:00 empty position. Pulled the tan wire in the trunk, turn the ignition on, stay's at 9:00. Checked the ground wire on pass. side tank strap, cleaned and reinstalled, nothing has changed, still 9:00. Took an ohm meter, tan wire to ground, 0 ohms..I have straight continuity to ground on this tan wire. My guess is sending unit or wire to unit. I guess next thing is to ground the tan wire to the gauge to see if it goes to full? I'm not new to twisting a wrench, but this electrical stuff gives me a headache.
