High current on BVM shunt

I have a new BVM-712 that I am installing. Even with the LOAD side disconnected it is reading a current of 8 amps.

I haven't done a zero calibration yet but I was surprised at the extremely high error readings.

I did make two small modifications, not sure if either one of them is responsible:

- I had to flip the PCB circuit board around to get the wiring to fit, but I believe I am using the right terminals.

- the power/temp lead was about a foot too short so I cut it and extended with some 12ga wiring. The connection is soldered and crimped.

Any thoughts?img-0398.jpeg
