Run 12v System w/out Batteries in Oliver 1

[GeoffChapman]

I have an Oliver Elite 1, 2020. I was winterizing it and before I winterized the outside shower station I removed my lithium batteries and remained connected to shore power. When I went to turn on the water pump, it did not come on; the entire 12v system is not working, while the 120v system works fine.

I called Oliver, and they thought I probably have to put the batteries back in to make it work.

Does anyone know if there is a way to get the 12v system working without any batteries in the Oliver. I have the FreedomX Remote Panel with the  Xantrex Freedom XC 2000 Inverter.

Thanks for any help!

Other than adding a device to change 120 volts to 12 volts, as far as I know you will have to put the (or at least one 12 volt battery back into the Ollie in order to get 12 volts to the water pump (or anything else that runs off 12 volts for that matter).  As long as it is charged up, basically any old 12 volt battery will work for your purpose.  I always have one or two 12 volt AGM batteries laying around in order to use with a small trolling motor I have.  This would be more than adequate to power that water pump.  Unfortunately, you are in Pittsburgh and I'm in the mountains of western North Carolina.

Good luck!

Thanks Bill. 
 

I wonder - what if I were to use 12v leads off my Jackery battery and connect them directly to the leads of the pump?  All I want to do is run it for 5 minutes…

Thoughts?

Just be mindful of the polarity.

Was wondering about that. I haven’t looked carefully at the pump motor, and there will be no 12v power to run a test.
 

Any wisdom on which lead is + or -?

With all other loads turned off (as to not overload the Jackery) just hook your Jackery neg to the ground buss with all the yellow wires, and the Jackery positive to the big red wire input of your 12 volt fuse panel .  Your pump will then operate as normal.  Otherwise you will have to cut the wire splice at the pump to feed it.

Right! Thank you.

Need some more guidance, please. I'm not very experienced at electricity, but I am game if it is safe. Forget the Jackery. Can I use one of my 12v lithiums instead?

Looking carefully - here's my shot at a safe 12v power

• disconnect the 120v land line
• take one of my lithium batteries, turned off and use a jumper cable, connecting the:
• negative to the 'ground buss with all the yellow wires' and
• positive to the naked bus on the far side of the 12 volt fuse panel? (left side of photo)
• turn lithium battery on
• turn off all 12v lights, etc
• turn on water pump and finish the winterizing

Is this good? Corrections?

Happy Thanksgiving!!!

Would work perfectly. Less trouble, winner winner.
