TR3B: Fuel Gauge/Sender Troubleshooting

["David Moag" <moag@ix.netcom.com>]

Hello all;

Another problem encountered when testing out my new wiring harness; the fuel
gauge doesn't work. When the ignition turns on it goes to Full (even with an
empty tank). When I reach in with a wire and pull up the sender so it thinks
that it is full; the gauge now drops to 1/2 --- but never any lower. I
switched wires at the gauge with no effect. I changed which post I attach to
on the sending unit with no effect. BTW --- positive ground with alternator
involved.

Thanks for any help!
