Got it all wired up!

Here is a picture of the shunt mounted next to the solar controller:

I had to cut out a small wooden panel to mount the meter as there was a cigarette lighter jack here previously and the meter wouldn't cover the hole:

This is a picture of the shunt for the Trimetric 2025RV battery monitor. Notice the piece of copper tubing so I can run my Black and Decker charger through the Trimetric and record the amp load. (Thanks BFL)

This photo shows that the B&D is feeding the battery 2.8 amps and the solar panel is outputting 19.2volts but because it is in total shade, there are zero amps coming from the solar controller. Volts are read right from the wires of the panel and the amps are read from the Morningstar controller. I gotta put the camper on the truck and get it into the full sunlight! To test the system I put the negative lead of the B&D charger on the Sunsaver controller panel input and the AMPs read perfectly...It works!

This picture is showing the battery is at 98% capacity. The SunPro analog meter is simply reading battery voltage.

This picture is showing the battery is at 14.6volts. The green LED at the top of the Trimetric is showing that the battery is being charged:

I ordered another V/A meter and I'm going to install it to read Amps and Volts from the panel and the second one will read Amps and Volts from the solar controller.

These meters are only $18 so, what the heck, I'll get this truck camper to look like the space shuttle one way or the other!...:B
