2013 TT Denali Power Jack OUT

[Suburbansilk]

we bought a used 2013 TT Denali 289RK to use as a tiny house on an RV riverfront lot in TN… our first week was good. Wanted to move the TT around the concrete pad a bit for some maintenance of the FHU… shore power all good with tongue jack. Once shore power was disconnected. The jack was DEAD. No light , no power… had to reconnect to power and leave the TT in its original spot… no fuse we could find. Towed 1000 miles before setting up .. we must have had tow vehicle charging ? Now what ?

Specs say it may have a 65 amp 12 volt power converter, battery charger. It should charge the battery lickity split when plugged into shore power or a generator.

Tongue jack may work when the TT is connected to the tow vehicle and the engine is running.

Circuit breaker on main 120 volt circuit breaker panel supplies the charger with power.

12 volt fuses on the 12 volt fuse panel. They may be 30 or 40 amp fuses.

If you have an inverter/charger installed, there may be a fuse or circuit breaker between the charger and the battery.

You may have a 12 volt power switch near the entry door that is turned "OFF".

There may be a battery disconnect switch near the battery that is "OFF".

There are other possibilities that are less likely.

Get a cheap digital voltmeter from your local hardware store and follow the 12 volt power from the charger to the battery. Charger should provide more than 13.0 volts after charging for a few hours.

Be sure to fully charge the battery for 18 hours one way or another soon. Storing a lead acid battery in a discharged state can kill it quickly.
