Power inverter issue

Hello all, I am new here and am armed with questions.
First I am not new to camping, but I am new to electrical on my camper. I have a 1979 Prowler 19E. It is a great sturdy trailer but when I was in Kentucky last summer I had several appliances going at once and then suddenly they stopped. (microwave, Fridge, a plug in box fan, my computer, and several lights. The trailer was plugged in.) I checked all the fuses and breakers and they are fine. It is only the plugs on the right hand side of the trailer. The plugs on the left still work.

I am wondering if I fried half of the inverter as it is 36 years old? It does make a electrical hum as all old electronics do. But not a buzzing like sparks jumping.
Or is something else wrong. What are your ideas?

Also the 12V system never really worked correctly. The lights were very dim, and if you ran the water pump they were non existent. Could that have been an early symptom? Thanks for the input. -Nick.
  • No ground fault receptacles on a '79 Prowler - I owned one. The power panel in the bedroom has two branches port & starboard. You lost one. Open the cover of the panel with rig unplugged then unscrew each wire and use a wire brush to clean the wire strands and a sharp point ice pick to scratch out the white powder in the holes the wire fits onto. Push-on push-off breakers can het weak. Try them all if any feel soft use KLIXON TOGGLE BREAKERS which are available online. Search Google eBay or Amazon. Take your time and make a project out of the electricals. Replace the power cord if the copper wire strands look purple or brown. Don'tcha just love the push in pull out hookup cord storage? The green & white prowler with jalousie windows was my third RV.
  • Thanks everyone for the input. I will check the breakers this weekend and make sure all the connections are clean and tight. I will let everyone know the results. Thanks again! -Nick.
