Line 2 brownout

Camping in 100 degree heat. Checked my power control panel in power management. Line 1 reads 114v, 13 Amps, 26%. Line 2 reads brownout, 78 volts 1 amp, 2 percent.

Everything seems to be working fine. Do I have an issue? What does line 2 brownout mean?

If there is anything substantial on line 2...yes, you will have a problem. I would check the pedestal and see if the voltages match what you are reading. Should have 120 volts between neutral and ground on both legs! If you don't, whatever is on leg 2 is susceptible to burning out, especially an AC unit.

Hopefully, your "power management" system will have disconnected line 2.

Like Scott said, check the pedestal. If the problem is there report it immediately. If not check where your cables connect to your converter (with power off). Most likely a loose connection somewhere. Could easily lead to overheating and a fire.

Thanks, line two is running the back air conditioner. I shut that off and nothing else seems to be drawing current.

Technician indicated the air conditioner could not operate on a 78v line. Suspects the monitor to be giving an incorrect reading. Suggested I reboot. I have both lines getting 120v at the source but when I read from the coach, it shows the drop to 78v on line 2.

It sounds like youíve got a bad connection between the source and the coach. With any load, it will heat up at that bad connection. If you verified the 78 volts with a separate meter, your monitor is probably not wrong.

If the AC is running, you don't have 78 volts. Now the problem is to find out why the panel thinks you do?

Flipped the breakers at the pedestal. Seemed to fix the problem......

I think I would move to another camp site ASAP.
