However pulled the trl around Wednesday wife said slides didnít work unless plugged into power so guess I will look for same reset wonít hurt to find where it is just in case anyway
This is where the Battery Monitors that measure discharge current as well as charge current (Like Victron, Xantrix, etc) really shine. Some can set off an alarm when battery state of charge reaches whatever state of charge you set as a floor. The Victron's come shipped with 50% as the default.
Not just a State of Charge monitor but a good diagnostic tool as well. When you plug into shore power you can read charging voltage and charging current. The Victron corrects the the readings for the level of charge or discharge current. As the current in/out increases the battery efficiency goes down so you get more accurate data.
You might have a blown fuse or tripped 12V circuit breaker at your converter. Attempting to operate the slide with a totally dead battery may have been too much draw on the converter all at once. Both charging current AND slide can be a heavy combination.
Even after two days of charging, your battery(s) may be shot due to the total discharge (how long were they left discharged?). The factory LED "Christmas Tree" charge indicator lights will show charged batteries but the charge is merely a surface charge on a damaged battery. When you hook up your truck that may be the only source of power to the TT until you reset breaker or replace fuse.
This is where a Multi-Meter is well worth it's price. Good ones can be had from Amazon starting under $20. Check voltage where the Battery Wire connects to the converter with the battery disconnect shut off. No voltage, blown fuse, tripped circuit breaker usually. Could be a bad converter but I wouldn't jump on that until I chased down the other items.
