Teleflex Amp Gauge Rebuild/Replace?

[Chuck Wheeler]

Michael, it is rare for an amp gauge to go out. Check the wiring,
especially around the shunt. I have found the shunts bypassed which
will render the amp gauge inoperative. I have a FC so our coach may
be wired differently, but when the batteries are in good shape and
charged up there is very little movement of the gauge. If we are
parked running on the batteries it will show a slight discharge, and
then a charge when the engine is restarted. If it has been parked
and plugged in there is no noticeable movement. If you have ever
watched a battery charges with an amp gauge on it you will have
noticed that it initially shows a charge and then falls off to a few
amps. The system on the BB will act the same. A few amps will not
show up on a 300amp gauge. If you are parked, not plugged in, and
place a good load on the batteries (lights, inverters loaded, etc)
you should see a discharge on the gauge. If so it is probably
working. If you are concerned about charging check the terminal
voltage on the batteries with the engine running. It should be
within a few tenths of the alternator output. I usually pay more
attention to the voltage gauge unless I think I have a problem.
