Ammeter/ Volt meter adjustment
I installed a cheap meter to read volts and amps sometime ago along with a shunt. There are two pots on the meter one for volts and one for amps. The volts I set with my volt meter but the amps I can ...

I figured out a way to get it to read amps both ways (if I can get it to read amps at all) using a small throw-type A-B switch I have in the spares box. A set of wires (opposite ways) from the shunt to the switch to A and B, then single set to the display? That way you don't have to swap wires on the shunt to see amps the other way, just throw the switch. (if it works)
I thought I had mine working when I had it jury rigged a few inches from the shunt. It was showing 33 amps, 14 amps, and 2 amps for different loads I tried.
Now at 15 ft away from the shunt using Trimetric cable wires it won't show amps at all. (you have to pick the right black wire of the two) Might need fatter wire than Trimetric uses?
