[Healeys] Fuel Gauge not working

[BJ8 Healeys]

Jonas, you should have continuity between the T and B terminals of the gauge
with no wires connected to them.  The functional BJ7 gauge I have on my
workbench right now reads 59.6 ohms between the terminals.  If you have no
continuity, then you'll have to send the gauge off for repair.

Have you attempted to calibrate the gauge yourself?  If so, did you make
sure you didn't loosen the nuts on the adjusting studs too much and let the
locating "feet" of the coil come out of the slot?  If the foot comes out of
the slot, when you tighten the nut the coil inside the gauge will spin and
break the wire, resulting in no continuity between the terminals.

1. No continuity between terminals on gauge (should I?).
2. Have Contuniuty between "cold terminal" and sending unit.
3. Have Continuity between "hot terminal" and ground
4. Checked resistance on sending unit rheostat - it goes up and down as it
should with motion on the float arm.
5. Have continuity between "cold terminal" and ground when green / black
wire
is connected the sending unit, and none when the wire is disconnected from
the
sending unit.
