John, pull off the green wire with black tracer from the T terminal of the
gauge. With a full tank, you should measure 95 to 107 ohms between that
wire and ground. With an empty tank, it should read 3.5 - 3.9 ohms. Those
figures are nominal, so if your measurements are fairly close to those your
sending unit should be O.K.

I have a problem with the gas gauge or the gas level sensor in the tank in
my
BN7 MK2. The gauge reads Full all the time, no matter how much is in the
tank
unless I really stand on the accelerator, and then the gauge drops to 1/4
and
then comes back to full. The gauge was rebuilt by Mo-Ma in 2005, and the
sensor has never been rebuilt or replaced. Is there an easy way to check
the
tank sensor? John Snyder, Port Townsend, WA
