Goal is to have bi-directional alternator and load current between X-Y, but not starter motor current. You can set full-scale deflection by how far apart X and Y are on the wire, or by putting a 100Ω pot in series with the meter.hmm, never thought of using micro-ammeter as currents can be quite huge
care to draw schematic just for sure Mike?
hmm, good thing with microammeter is that i don't need to cut or drag high-cauge wire all over the place. is that potentiometer calibration so to say?
I have several. They are available from "surplus" dealers in the US...Can it be, i can find 50-0-50 microammeters only from ebay? oh man...
...
I am also not sure how you want to handle the huge current difference between normal charging and starting. ...
We already talked about this. Dont run the starter motor current through the shunt...
