Power to Rig

Bum jumper cables? Bum connections? Jumper cables are notorious for being flaky.

May have to "cycle" the disconnect switch....OFF then ON.

And while it is usually not necessary to remove a battery to keep it charged........if this is Arizona in the summer time, the HEAT can age a battery a LOT. Maybe cut it's life in half overall.

Thank you all. I tried the power cable to the truck. No worky. 12 volt switch in right position. Bumfuzzled. Will try running neg to neg and connect the two pos RV cables and try that. Thanks again.

Did you hook it up backwards the first time? Is the reverse polarity fuses now blown?

Why not leave the batteries in? Hook up a disconnect and just kill the power. I do that and they are good for 3-4 months at a time as long as they are fully charged when I store it.

B.O.

Usually there are two or more wires to each battery post, so you need to collect them all as though they were on a post and connect the jumper clamp to that collection.

Eg, you might have only connected to the wire for the jacks or slide and not the rest of the rig.

I use vice grip pliers to hold several ring terminals together when they are not on a battery post. Jumper clamp on the vice grips.

If connected properly I don’t see why the jumper cables would not work. Any chance your 12 v disconnect switch is in the disconnect position?

Yes. It should.
Might measure with a meter next time.

If not in indoor storage, leave them in the RV and use a trickle charge solar system. Mine is 25 watts and works great.
