battery problem

It appears all of our batteries - coach and engine have died. We have plugged in and they do not take a charge. What seem strange - there is not enough power to even light up the microwave, light on refrig. Lights are very weak - even though we are plugged into 50 amp power.
We did have work on the battery tray, so all batteries were unlocked and reset. Connections are tight.
Is it normal for no power when plugged in even though batteries are dead?

When you are plugged into shore power everything should work. The converter may be bad and not sending the correct voltage. Check the volts going into and away from the converter and that should give you a clue.

Unless you have a very unusual system, your microwave runs on 120V AC,m not on battery power. Your symptoms suggest that you are not getting any shore power. Do any of your outlets work?

If the microwave doesn't light up, you have a problem with shore power. Either the outlet or your cord (or adapters, if any).

Your AC shoreline is not working as mentioned. Start your vehicle engine if possible. After it runs for 5 minutes start your generator and let it warm up for 3 minutes. Shut the big engine off and let the generator run. You should get the microwave light and the other 12 volt lights should come on.

If the microwave does not light up then you have some breaker issues to deal with. Your main panel has breakers and there may be a couple of breakers right on your converter/charger,.

OK I just went through a similar problem.
AC shore-power connected and on, but no power in coach. Tried running the generator still no ac power. The house batteries were under 8 volts, dead, and the switching system to change from batteries to ac power was not functioning. The internal switching systems are operated by the house batteries and must have 12 volts to function. Put external charger to house batteries, as soon as it got to twelve volts the switching system activated and the shore power connected. The on-board inverter system and charger also came back on-line. However, discovered the main culprit to be bad house batteries, they had no life left and after disconnecting from shore power they immediately went back dead.
