Electrical problem

[sabourinpoirier]

On the information panel L1 shows 120 V and L2 shows 5 V so front AC and microwave are not working. When you use the generator only the microwave starts. After a while, I got a message of low battery. Is there a switch other than the ac braker in the electric panel. I had a message of E7 on the thermostat. I made a reset as the instructions but the error keeps on coming back
Would somebody have a idea.
Thank you

I believe E7 means you have no power to the AC unit. I have had that when my generator would shut down.

As for the panel, L1 showing 120 V is correct. L2 showing 5 V is incorrect. Are you plugged in to 50 amp service? You must have 50 amp service in order for everything to work. You cannot be plugged in to 30 amp service with an adapter, won't work. If you are plugged in to 50 Amp, then something is wrong with L2, no voltage. Should be 120 V just like line 1.

If you are plugged into a 50Amp then I would check your wiring in the transfer switch. You may have a loose burnt wire or terminal.

I was thinking the same thing. When my neutral wire in the cord burned out the lug on the transfer switch I got a Low Voltage Warning message on my Inverter Control Panel. I traced it back to the lug where the cord's neutral was connected. unfortunately the stranded wire wasn't snugged up by the lug screw and arced until it eventually almost burned through. It showed low voltage on both inputs since they share that neutral.

Always best to solder those tips before tightening down the lugs.

Being he has 120 volt on one leg I preduct that L2 is the problem and not the neutral. If the neautral wa sloose you would'nt get 120 volt on either leg but low voltage on both.

The problem is the transfer switch. When I opened the box under the bed the wires and the box are melted together. There is a recall on the box from Forest River.
Thank you for your support.

Was the box under the bed the breaker panel or the transfer box? Our transfer box is outside by the power cord and breaker box is under the bed. What model of MH?

[sabourinpoirier]

The transfer box is located under the bed between power cord entrance and braker panel located at the foot of bed. I have a Charleston 43'
