Ammeter/ Volt meter adjustment

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?

Mine will read amps. With nothing on it reads -.4 amps. I assume that is the Co2 detector. Each light that I turn on adds about -.4 amps. I just question the amps from the alternator, I thought I would get more than 5 amps. I will recharge with my 40 amp B&D charger and see if it compares closely to it. My batteries have been disconnected with no charge since Oct 1st but are probably still better than 90% so they won't take many amps.
