If the LED panel works then the fuse is not the problem.  Dake
Collins and I just fixed his.  He had a bad pump, a broken wire going
to the faucet, and a bad connection from the ring terminal at the
faucet to the wire.

You'll have to get a pin and trace the voltages and or resistances.

Resistance across the motor (leads unplugged, they're the blue and
brown connected to the two yellows in the secret compartment) should
be a few ohms.  If it's a few hundred kilohms instead, the pump is bad.

There should be 12 volts between the two yellow wires when the faucet
is turned on.  If not, open the faucet and check for 12 V to ground
on one of the terminalsl  If none, check for 12 V between one of the
terminals that switch is plugged into and ground.  If you find it,
then remove the city water and tank water lines from the faucet, get
your pin and start probing the wires to find the break.  Start by
checkin between the ring terminals and the wire half an inch away.
