40 amp fuses at inverter

[Tewksburyduck]

I blew the two 40 amp fuses at the inverter by hooking up the battery cables in reverse. I have not replaced the fuses yet. Now, when hooked up to shore power I do not get sound through my speakers with power the genesis radio. Also, the DVD player will not insert a disc. I will find replacement fuses but I'm wondering if the radio needs those fuses to fully function. I did pull the radio from the wall and the fuse there is not blown.

The radio operates off the 12V, so you do need those fuses for it to run

Tewks, just to clarify, it's the CONVERTER, not the inverter.

and since those fuses are from the battery and the radio is 12v, then it may need them to work.

Check for a fuse holder behind the radio.
Dont ask me how I know.

Ps you'll have to pull the radio.

Replaced the 40 amp fuses and still no sound from speakers when set to on position. Also will not accept a DVD. Any suggestions? The fuse behind the radio looks fine.

does your other 12v stuff work(lights, water pump, furnace), without being hooked to shore power?

If the radio is turning on, ie the display is lighting up, but you get no sound you may have damaged the radio. The fuses will protect the wires and such from overheating but they don't react fast enough to stop the radio from being damaged from the reverse hook up, DC electronics don't like to be hooked up backwards.

Furnace, lights, and water pump work while on battery power only.

It does not take much reverse current to fry a computer. Sounds like it could be damaged. Did you check both fuses in the radio? There is one that supplies "full time" power (clock, panel lights, etc) and one that supplies "part time" power (all the rest - like DVD player).

The full time power is an inline fuse and the part time power is a "blade type" in the back of the radio.

You may need to meter them for continuity since they can fail at the solder joint and the open may not be visible.

The blade fuse behind the radio looks good. I have not seen an inline fuse. I will look now though.

After physically looking and looking at the wiring diagram for the Genesis GT-2.0 I don't think there is a second fuse behind the unit. I will call the dealer tomorrow. Thanks for your support. That's what makes this forum so invaluable.

The best way to see if the radio has power is to pull it and use a multimeter to verify voltage and ground. Some radios may have 2 wires for power

Test with a meter. Some look ok but aren't.

I bought a Genesis 2.0 replacement unit on Ebay for $59 + $14 shipping. It was being sold as an overstock item and was described in the add as used. I contacted the seller to make sure I could return it if it wasn't fully functional. I installed it this evening and everything works as it should. I hope everyone can get out this weekend. We are heading to Terrace Pines in Ossipee, NH.

There was an identical thread last week on this subject - my buddy did the exact same thing with the same model trailer 2 weeks ago and he replaced the two 40A fuses and there was an inline fuse in the Genesis unit that was blown. Once replaced, he was good to go.

Thanks. I did check and replace the inline fuse with no luck. The fact that the disc player wouldn't accept a disc I assumed it was fried. The replacement from ebay did the trick.
