My meter is powered off of the battery and is on all the time. I've run the + line off of the battery through the coil. The readings are fairly erratic making me wonder if something is wrong with it. I can't see it now- we're sitting on the Sterling Highway waiting for authorities to open it back up when the wildfires are away from the road. We've been here since 1:00 pm yesterday. Thankful to have the camper, but my meter is behind a slide wall, and I can't put the slide out due to trooper and forestry people driving by the camper on a regular basis.
I'll see if I can make something out from the instructions but if I remember right, I had a hard time making anything out from them.
