Inverter

Hello all - long time reader, rarely post here however I do have a question.
Had little mishap that damaged my electrical cord from RV to truck.
First time ever I hooked up to bumper connection - cord slipped out through tailgate and bounced along road for a while.
Repair guy I use said that the charge line from truck wasn't working - fuse was blown.
He also said Inverter wasn't working. We were on dry camping trip and the generator worked fine but did not charge batteries. Had to connect it direct to batteries to get enough charge to lift RV to hitch.

All this leads to my question - how do I tell if inverter is working or not. This morning gauge in trailer showed no battery charge. I now have it plugged in 30 amp outlet and will see if i charges that way??

Thanks for some non technical advise.

  • Disconnect the battery from the RV. Plug the RV into 110 volts. If the 12v light work then you converter is working. When they go out they normally don't put out any amps.
  • My advice is to check things with a voltmeter. It's a converter...unless you have an inverter/charger.
  • I assume that you are referring to the converter, which produces 12v DC from 120 v AC. When the converter is working and you are plugged into 120 volts, and the source can be generator or a campground outlet, then you should have 13.6 volts (I may be off a few tenths here) at the battery terminals.
