Over-charging or maybe a short somewhere?

Battery Problem

Shorted cell in the battery. May be a random failure.

It then draws lots more current from the battery charger and gets even hotter.

The battery is basically toast. No pun intended.

Verify proper output on the converter before trusting it again.

Welcome !!!

Without any more information:

1) Normal operation under load

2) Shorted cell in one or the other batteries

3) Normal operation with charger running at 14.6V and high outside temperatures

4) Shorted cable somewhere downstream of the battery

5) Blown converter / charger

6) Blown solar charger

7) Dead mouse in with the battery

8) Heavy load connected to "Zamp Solar" plug ( or heavy charger).

9) Low fluid (water) levels in one or more cells in the battery ( so check this now ....)

10) .......

So indeed a variety of possible causes. To help narrow things down:

1) Is this a brand new trailer / first time out? Is this first time this season?

2) If the trailer is not brand new, how have the batteries been cared for?

3) Did this just come up or has it been an issue for a while?

4) What is the voltage on the battery?

Indeed all of that is in no particular order. Please do *not* assume the important stuff is early on either list
