taylorbob1: Can that internal shunt handle the starting current of the generator which I would guess approaches 100 amps?
Also with that monitor you have to run the negative battery cable back and forth to wherever you mount the display. This will require big #2 cable.
Here is a more comprehensive battery monitor that I have used that is easy to install: the 500A shunt mounts near the negative battery terminal then a cable carrying the shunt voltage and the + and - power wires goes to the remote indicator. See
