DC current draw at rest, 2.3 amps with nothing on

Thanks all.

I took the charging unit out and put on a bench to make testing easier.
Found a questionable solder joint which I re-soldered.
Applied battery power to the +- terminals, still 2.3 amps.
No components burnt or any other visual indications.

Current battery is a single marine deep discharge, powering lights, roof fan and a heater fan.
Someday trailer will have a lithium in its place, maybe 2.

Checking prices it looks like replacing the entire distribution panel with charger is just a few dollars more than the charger alone.

I guess I will change the whole thing out for a Progressive Dynamics Mighty Mini 60 Amp PD4060K unless there is a better option you might recommend.

I like PD, and if that is discontinued it is a good upgrade. thats weird to have a high draw like that, how old is it?

Make sure your replacement has high enough voltage for lithium

Make sure your Trailer Brake a way switch is also disconnected. There may be a slight fault in it drawing power. The Brake a way is wired direct to the battery POS post. Also, check your LP sensor. It may also be wired direct and not be fused at the Fuse center and have its own fuse. Doug

A 2 amp draw is exceedingly high for any modern converter. Maybe a few milliamps but 2 amps is huge.
My trailer idles at 500 milliamps (1/2 amp) with the fridge running and everything else off but not disconnected.

That is not a normal parasitic draw for any converter. It should be a few orders of magnitude lower.
