e24, 630 but hopefully family enough.

Fuel level gauge goes hinky. Pulled the in tank sender, cleaned to look fine and operable. Touching the wiring behind the dash, speedo, tach box, gets the fuel needle to jump.

Pulled the box, multi plug, to see the plastic circuits, etc. Ground wires ? Bolt to frame looks clean, unmolested but I'll do it anyway.

Any suggestions on what to wiggle, look for ? I don't see anything will blow up if I have the battery hooked up, turning on the ignition to see if lights, etc. work but I may be wrong.

After 35 years the sending unit can look fine, but have some corrosion on on contact surfaces which give erratic readings. Also I can't emphasize grounds enough, run a new, seperate ground from the engine to the body. 12 gauge or better.

This is what finally worked for me. There are other posts that address this topic that I've made before, but the link has finally solved the problem. No more erratic fuel gauge and it goes to the red zone faithfully before the light comes on.

Great! Thanks! Almost began reassembly, not seeing much dirty, etc.

Can't turn the key with steering wheel off. Must be the shaft lock, afraid to go horsing, breaking little plastic things.

My insanity makes no sense. The car is stripped inside. I took the engine apart to the bones, cleaned, learned, it runs great. Now the dash, learning wiring, or at least what the rats have done that needs routing, organizing.

While the decision to fix the rust has been made. Never happen. Buy a rust free 633 and play parts choose and swap.

Climb the mountain because it's there. Fix the gauge because it's erratic. How high is up ? Never trust a naked bus driver.
