Thanks, Dan - that is just what I'm looking to do. Nice job!
You mention you ran one fused wire from the battery to the ammeter. Then another to the inverter's positive binding post? I thought the inverter converts DC to AC, so not sure why you have it in the circuit. Or did you mean to say converter? I guess I understand how an ammeter is wired inline in a positive side of a circuit, but a little confused on how it reads the charging amps when your converter is plugged into shore power. Do you run a wire to the converter?
What I want the ammeter to measure is total current flowing into or out of the battery. The inverter (aftermarket _INverter_) was just a handy spot to tie into the trailer side, and a new wire was run from the fuse at the battery to the amp meter.
Take a look at the Scamp
wiring diagram as it comes from the factory. ( http://scamp.n0kfb.org/manual/electrical.jpg
) since I want to measure all current to or from the battery, the fused lead from the battery was brought into the trailer and run up to the amp meter, then back down to the fuse that is under the bunk.
The circuitry hasn't been changed. The wiring from the battery just runs up thru the meter before connecting where it had originally.
Jeeze - that's long explanation. I hope it make sense!
