12v power problem

[bigt1739]

I’m plugged in to shore power, all 120v systems are working...I have no power on the 12v side. Battery shows 2/3 on “performance center lights”. Gonna start looking into it, where should I Start??

Start by putting a piece of tape over the "performance center lights". NOT. But seriously, those lights give you very quick general information. It's time to break out a Multimeter. Check your "converter" volt 120 circuit breaker. Check your TWO 30 or 40 reverse polarity fuses. They are side by side on the converter. Check your battery disconnect switch if you have one. See if you slide will move, check the voltage on your batteries. you want 12.5 or better. 13 or better with the converter on. That should keep you busy till breakfast.

By "performance center lights" I'm guessing your reading the Tank fill and not the battery. My lights for the battery say C, G, F, and L. Tanks say F, 2/3, 1/2, 1/3, and E

Thanks for the replies. Battery not charging. Reading 2v...I’ll get into it more when I get home. Luckily I was able to get the awning (no slides) in by hooking another battery up...my guess is I’ll be getting a new inverter/converter this week

check your 12v 'cutoff'(salesman's switch), usually by the entrance door.

Don't jump to conclusions.
Check the things cavie mentioned.
It may be operator error.

Ditto; except, even if the batteries are disconnected the converter should still supply 12 volts to the coach with shore power connected.

That is correct. That's why I mentioned the reversible fuses and the converter breaker. Everyone wants to take the easy way out and just replace things instead of fixing the problem and learning something along the way.

Fuses are good....rang them out with a meter...breaker is good and there is line voltage (120v) to the inverter..battery reads 2/3volts...I hooked up another battery and everything came to life.

Don't know if your coach has one but if you have an emergency start function you could have used that to get the awning retracted. That way the chassis battery would have been supplied power. Could have started the engine beforehand also. Just a thought.
