Hello...I have an older 29' puma we used after Hurricane Michael during rebuilding and I have 120vac going to it. I would like to use the 12 volt onboard system, but without batteries. I'm thinking a step down voltage transformer might do the trick, tying into the circuit panel dc side. Anyone ever try this? Thanks in advance.

A standard converter used in trailers will supply regulated 12vdc without a battery connected.
 
Thanks for the reply. That’s what I thought too. After the hurricane, we were flooded, 14 inches water in the trailer. When I reconnected to shore, electric bill tripled! I replaced the converter, but that didn't change anything so I ran a drop cord and just used tv, fan, Lights, etc and got by.
 
So, you want to apply 12VAC to your 12VDC circuits?

That's not what I read. He wants to bypass the converter. Sounds to me he has water damage that needs repair. But because he replaced the converter already, injecting power won't fix the real problem.

A DC amp probe to isolate the offending circuit would be the right approach.

I appreciate the feedback....it's all not a big deal. I'm just piddling around with this thing. I'll do a little studying on the dc amp probe, sounds like a plan. The flood was worse than the 155 mph winds from Michael.

Usually is. Home Depot sells a nice Klein tools meter. Model # cl390 is the one I use but there are many out there. Make sure the clamp registers AC and DC.
