I looked at a range of possible ways to monitor my battery output, and most of them I found costly. Someone used one of the multimeters to monitor a solar panel, so I thought, why not? Harbor Freight is a half mile away from my house, and they sell their little multimeters for about $3.00 on sale.

I joined some leads left over from a more expensive meter that died to the test leads on the Harbor Freight model so I could reach from the battery to outside the bench seat. Then I crimped on ring terminals sized to fit over the battery posts. (In my 1994 SD, the battery is in a box under the rear seat, dinette side.) I had the seat off for other repairs, so I just ran the wiring under the fiberglass bench. I put Velcro fasteners on the back of the meter and the bench (in case I want to change the position later) and was ready to go.

The cheap little meter has a back light, on/off switch and will shut itself off if I forget to do so. It is awkward to get down and read it, but it's not something I have to do very often. Works for me!

Thank you for the idea Charlie. I stopped in at Harbor Freight today and picked up the same one you posted in your picture. I'm good to go.
