Thanks,
Pete

This is the easiest problem to fix. The other main issue is a grounding problem somewhere in the guage panel or along the circuit. This one always takes me a little longer to track down. Is your guage bouncing or is it always stuck on full? | | | | | Joined: Nov 2006 Posts: 231 'Bolter | | 'Bolter Joined: Nov 2006 Posts: 231 |

If it does get a new sending unit. Somewhere in the mid 60's they changed the ohm's rating on the sending unit I think it is 66, yours should be a 30 ohm and the later will be a 60 ohm. Someone may have already changed it and got the wrong one, look the screw heads over real goodand see if you can tell if they have been removed. Check with Tony at 4-5-6 he might have what you need. Also check if the tank is grounded,

This "strap" is a conductor and I just soldered it back together and now the gauge works fine. I know of two units where this has been the problem. Hope this helps.

Jim My 65 sending unit has that problem too. The PO must have found it. This pic shows his added wire rigged up for a "fix". I think the solder repair sounds better. Is the wire fix in the photo dangerous?  Sending unit with broken strap | | |
