Trying to determine the cause of my fuel gauges going to full and staying there when key is turned on. Checked ohms at the tank and seems correct. Checked ohms at fuel gauge before turning key switch on which matches reading at the tanks. Once key is turned on gauges jump to full, although I know the levels are around half in the tank. Trying to determine if this is a ground fault and if so determine if the ground fault is at the tanks or gauges. 3 tanks, diesel. All three gauges share a ground with other gauges that are working correctly.
If a ground fault at the senders how to track this down. Odd that all three gauges are doing the same thing 2 tanks are in the engine room, port and stbd, one is under the aft berth.
Performed a continuity test on one tank from neg terminal on sender to bus block/bar and get a positive continuity signal on several connectors. Trying to go back to high school electronics class, but that was 49 years ago and just can’t recall how to full track a ground fault, if this truly my issue.
Suggestions welcome,
