2015 Montana 3100RL blowing reverse battery connection fuses.

[Benbrookad]

As I said in the title, I have a 2015 Montana 3100RL and it is blowing the four 15 amp reverse battery connection fuses on the converter. I have checked and the battery is connected properly and it is a new battery which I had fully charged before putting it in the 5th wheel. Any ideas as to why it keeps blowing the fuses? It is hooked up to an outside 30 amp power source.

Battery cables on a RV are colored differently than an auto. Regardless of the color, one goes to ground and the other goes to the converter. If the Reverse Polarity fuses in the converter are blowing you have the cables reversed.

I traced the white wire back to where it was connected to the chassis of the 5th wheel and I connected it to the negative side of the battery. The black wire went to a connection terminal and I connected it to the positive side of the battery.

Ok, let's go the other way.
Disconnect the battery. Remove BOTH Terminals.
Make sure they don't touch anything.
On shore power.
Check the output voltage of the converter.
Verify positive and negative cables.
Go to the battery compartment and Verify positive and negative cables.
Connect accordingly.
Check reverse polarity fuses.
