No power in camper

[Tractorboy924]

I have a 92 Sierra TT and I no longer have power inside the unit.. either plugged in or on battery. I charged the battery a but and also checked the power level inside status device and dead.

Im guessing some sort of main breaker has tripped on it?? as I dont get lights or anything even in battery mode???

Im guessing breaker tripped. would that block all power to the camper????

Thank you for help

A breaker tripping could certainly be the problem or a main fuse blown. There are many different systems and set-ups for electrical.

I would check all the breakers and all the fuses. Be sure to turn the breakers off and on and check fuses for continuity and corrosion.

I believe some TT's work off of the 12v battery and inverter/converter only so a dead battery could cause everything to not work if yours is this type.

This is my limited knowledge but I'm sure others will have more ideas.
Good luck.

Does "no power" mean no 12v or no 120vac, or both? The breakers are for 120v shore power and supply wall outlets and a few appliances. Everything else is 12v and gets its power from battery, or the converter while plugged to shore power. 12v circuits will have fuses rather than breakers in nearly all cases.

Many things in an RV need 12v power to work, even if using 120v shore power as the main source. The circuit boards in appliances, for example, use 12v power all the time.
