Electrical problem now

[fuzz508pd]

Well I wasn't paying attention as it started to rain today and connected the battery backwards. I replaced both 40a fuses that were blown. But my microwave and tv are not working now on battery. I didn't have a chance to plug the unit in. Is it possible I fried them? Even though the fuses blew like they were suppose to.

Did they work on battery before? Normally, these work on 120v only. Do you have an inverter that supplies power to these two? If so, you might want to check it out. Reversing polarity might have done harm to an inverter.

Microwave and TV are 110VAC need to be connected to shore power

ADDED: Those Fuses were reverse polarity fuses on the converter 12 VDC circuitry

Yeap down the road from you and was raining at least not that white stuff

Check your fuses in the converter not just the circuit board.

Haven't seen a 12V microwave in an RV. They do make 12V TV's but I'm willing to bet both are 110VAC and require shore power to operate.

Well I guess I never paid attention to realize the microwave and TV didn't work on battery, as I never tried it. So I learned a few things today! Thanks for all the help. And all that needed replaced were the 2 40A fuses that guard against reverse polarity and a fuse for the radio.
