I am getting a 24 volt reading in my 12 volt RV, do I have a bad inverter?

Question

I have 24 volts showing on my volt meter when I check my voltage. I have disconnected both batteries and only hooked the battery back that cranks the motor home. Still I get 24 volts. Could the inverter be the problem?

Answer 1

You have the batteries hooked in series and they should be hooked in paralell.

Answer 2

I don't see how. That's the wrong end of the inverter. That takes AC and makes DC out of it. I don't it's even connected to the electrical circuit. Are you sure you're measuring correctly? You'd be burning out light bulbs and our turn signals would be fast. Your dash lights and headlights would be very bright as well. Where are you measuring and what happened to make you check it in the first place?
