On a more important note:
A 70Amp alternator is undesized for charging a 220Ah house bank and
will never fully charge the bank, which will lead to premature battery
failure.

I have a 70A alternator and 220AH house battery capacity. I'd like to
do this myself if I can. I have a small shunt from a 12v battery
charger but I don't think that will work. If the correct answer is
"you need a 50mv, 70A shunt", where do I get one? Lot's of people
selling 100A, 500A etc for solar pannels. Thanks for your time.
