Re: [DML] Possible Frozen Fuel Gauge

[Martin Gutkowski <webmaster@xxxx>]

The fuel guage is an ohm-meter. It measures the resistance of a coil whose endpoint
changes as the float travels up and down. When you disconnect the sender, the resistance
is infinite (open circuit) so your guage points strait up. Check the connector to the
sender, and give it a clean. If it continues to happen, it's probably the internals of
the sender going bad.

This is the first car I've seen where the fuel guage works continuously, even when the
engine's off. (note to self: check wiring diagram....)
