Fellow "A" body maintainers,
Racking my cranium trying to figure out this fuel gauge anomaly. Needle moves ever so slightly to just above the "E". Here's what I've accomplished:
- Installed new tank/sending unit and got that slight movement above "E"
-grounded power lead at tank and gauge will peg out to full and return to empty. That tells me wiring up thru the instrument cluster is good.
-Removed sending unit. Rheostat ohmed good from empty to full. 3ohms to 84 ohms
-With unit out of tank and grounded I manually moved float and gauge read empty to full.
-Re-installed sender and grounded as per Mopar and with half tank fuel had no response to gauge movement.
-tried all different variations placing ground in different locations. All continuity checks were good.
-Ensured I had my engine to firewall ground intact.
-Ensured cluster was grounded to dash.
- Manipulated ignition switch to see if any help but none.
-Tried a second sending unit....same result
-Just for giggles, I replaced the volt limiter on cluster...same result.
-I turned the sender upside down in the tank and it read full on gauge. Re-installed it right side up and no reading.
- Could it be a baffle in the tank is installed incorrectly? Need you guys to help me right the ship.
