Can I tow/connect power w/o battery?

Any issues towing my trailer or plugging in the shore power cable if the battery is NOT in the rig?
Assuming the cables for the battery don't touch.

Should be okay. I pulled battery on my first TT because I never used it. New TT has battery pulled and I hooked it up to TV while in storage to get my CD out of the radio!

The only problem doing this is that your trailer battery supplies power to the breakaway switch for brakes if it would ever become unhook from your tow vehicle. Not a safe thing.

If the trailer has brakes then you MAY NOT TOW IT without a properly charged battery in place, this is a safety issue, and a liability issue, the reason is that said battery is part of the emergency (Break-a-way) Braking system and without it you have no emergency braking system, period.

As for plugging in: SOME converters, most notabilly the old Magneteck 6300 line, really do not like operation without either a battery or a battery simulator. Now sometimes they work, but I'd not count on it.

That is the bad news

now the good news.

I have one of those handy-dandy jump start devices,, I have had to use it many times over the years for assorted vehicles (not all mine) (Worked for a time for a tow company, many owners coming to redeem their impound needed a jump) .

I'm on my 3rd unit now... This is battery enough for the job, Set it in the battery box hook it up and you are good to tow.

IF you have one of those old magnetek converters.. May I suggest a Progressive Dynamics 4600 line from Best converters.

Replacing the guts of the Magnetek with the PDI woudl be like upgrading from a skate board to a Cadillac it is true, (Worst to best) but hey... That is why I recommend it)

See, I wasn't even thinking about the breakaway feature.
Always better to stop, think and ask.

Although, if it does ever break away, I dont really see it staying on the tires very long, so not sure how much good that feature would do.

I do have the battery for it. I had just taken it home to charge a few days ago and was now going to bring the trailer home too to winterize it.

Thanks

Some of the cheaper converters/inverters use the battery as a control for voltage. Without it in place there can be higher than rated voltage getting through.
