68 Dart fuel and temp gauge not working
Common problems:
Voltage limiter. Buy a RTE solid state one
Bad connections between limiter contact fingers (if this is not a Ralleye dash) and the PC board traces. Solder jumpers across
Bad connections at gauge stud nuts. Loosen/ tighten nuts several times to "scrub" the connections clean, and consider replacing nuts
Solder around base of harness pins after cleaning, inspect for damage.
The electrical "path" for the gauges is ignition switch----harness connector pin----to voltage limiter---branch off and PC board trace feeds power to each gauge. Through each gauge, then back on traces to harness connector pins, and out to senders. Fuel gauge goes down to left kick panel connector, out to fuel tank, temp goes through a terminal in the bulkhead connector and out to temp sender
You can use resistors or a variable / rheostat to generate proper test resistances to check gague accuracy.
