This is my DC distribution box for the truck. It has a main power switch (on the left) and six others that control one of six pairs Andersen Powerpole connections on the back. The other two are one input and one that is switched along with the main power. All 8 are protected by ATO/ATC fuses (there's a clear plastic fuse cover for the fuse holder that's not pictured to cut down on glare).

There is also a combination voltage/ammeter. As a late addition, I added a latching push button switch to enable or disable it. I did this because the meter can be set to work in one of three ways, voltmeter, ammeter or alternating volts/amps. When it is in the volts/amps alternating mode the ammeter flashes the amperage reading and I thought that might get distracting during driving.


This image is a bit blurry because I didn't let the camera adjust to the outside (in the 90's) temperature. It's the only shot I have showing the two Andersen Powerpole panel mounts though.

The ammeter uses The Hall Effect to measure current. As such it doesn't need to be in-line (see the white loop at the bottom side of the image). This was another late change. I previously bought another voltage/ammeter with a shunt. When I was a bout to install it, I found it had to go into the negative side of the circuit (apparently a lot of people find this out late judging by the manufacturer's website). I was fortunate to find the Hall Effect meter and also fortunate that all these meters seem to use the same form-factor about 1X2 inches so I didn't have to cut or modify the opening.

This is a poor picture of it powered up. It's using a PS that's not too much above a wall wart. That's probably the reason for the big voltage drop.

Some images for my old Flexradio 3000 and HRD. Ive replaced it with a Flexradio 6300.
