Shore power 120 v guage

[mesquito_creek]

my sundancer is on the trailer. I unplugged the shore power for 5 days. When I plugged it back in the gauge didn't come up to 120v but I had 120v at the outlets etc. I came back about 6 hours later and now it's reading 80v? Shouldn't the voltage be 120 as soon as it's plugged in? Batteries are a solid 13v the whole time....

I would start with checking the connection for voltage gauge.

Yes, it should read 120V right away. Just for good measure, turn the main breaker off and back on.

Pull the panel and use a DMM (set to AC volts) to check the actual voltage at the back of the gauge. Look for loose or dirty connections back there, too. May want to remove/clean just because. Remember you are dealing with AC side of things and take the proper precautions.
