The current (AMP) display is not working correctly. It is reading 94 AMPS and I know that is not correct because if it was, the breaker would trip. I have the shunt connected between the alternator and the aircraft load. On one side of the shunt I have the EMS-37 pin 24 (orange/green) wire connected with a 1 amp fuse in series. On the other side of the shunt I have EMS-37 pin 25 (orange/purple) wire connected with a 1 amp fuse in series. Any idea of what is wrong? Or is there some setup that I have to do? Thank you. :-/

So a first easy test with the amps measurement is to connect the two wires together right at the shunt. They still need to be connected to the shunt, but to the same terminal. Which terminal doesn't matter.

Doing this should cause the amps reading to be zero all the time. If it isn't, you have a wiring issue, such as a broken wire. If it is zero, then something funny is up with your wires at the shunt.

There shouldn't be any configuration you need to do.
