Hoo boy. If you put the TM in storage for nearly a year, and didn't disconnect the battery, the parasitic loads (they exist in every trailer, not just TM) drained the battery flatter than flat. Most batteries don't take well to this event - many never come back.

When you plug in to shore power, do your inside lights work? If so, the converter is OK. If you disconnect from shore power and the lights go out, then either the battery or the battery fuse is at fault.

So check the fuse, as Dick suggested. Check the water level in the battery. If both of these are good, try substituing a known-good battery - take the battery out of your car, for instance, and install it in the TM. Then, WITHOUT plugging in to shore power, turn on a bunch of interior lights. If they come on and stay on for a couple hours, plug in shore power and confirm that the converter keeps the battery up.

Good luck

Bill
