Can I run refer on shore power with batteries out?

[brad1]

I've got to remove my batteries to get them tested. I've got stuff in my refrigerator. I assume the refer needs some power to run on propane. Can I remove the batteries, then plug back in to shore power while they're out to run my refer without screwing anything up?

In a word, yes. Put your switch in the STORE position and the converter will still provide DC to all loads. Tape off your battery connections to be safe.

If you have 120V electrical power you should be able to run the fridge on pure electric power. You still need the 12V DC for the fridge's control board, but if you've got 120v and 12v from the converter there's no need to use propane. Leave the fridge on Auto and it'll choose 120V.

Thanks for the quick replies. I appreciate it. Whenever I go anywhere near electrical stuff I anticipate sparks flying. None did. Again, thanks.

Hi

Just to be very clear:

Shut everything down.
Pull the shore power.
Pull the batteries (negative terminals both come off first)
Tape off the positive terminals
Double check the tape
Re-attach shore power
Turn stuff back on again

To re-install the batteries, reverse the process.

Sorry if that's in the "obvious" category ....

Very valid suggestions above; however........
One of a batteries 'jobs' is to act as an accumulator, (or 'snubber') to swallow voltage spikes.
If you are sure of your shore power, go ahead and do your thing.
If not, attach any battery, even a 'pooched' into the circuit.
It will still act as a snubber if needed.

Some of the older converters had very poor filtration and regulation and used the battery as a filter. I replaced the Parallax converter from my 2001 Safari with a PD9260. I am, and have been, using the Parallax as a 12 VDC supply for radio testing with no adverse results. It's a not so great battery maintainer, but a good power supply.
