Funny that should come up again today.
 
I happened to be out in Ducky and checked the PLM. Line 1 read "1" as usual. Line 2, which is usually between 124-126 was jumping between 167 and 174. After several seconds of observation and it kept on jumping like that, I went and turned off the circuit breaker in the house.
 
What next?
 
Thanks for any guidance,

The obvious, use a voltmeter to check the accuracy of the line monitor

Thanks.

I'll be on it when get back to home base, or stop in Mechanicsburg, PA on our way to New England this summer.

use a voltmeter to check the accuracy of the line monitor

I checked both main breaker panels and got about 121 volts on all four lines on the left panel, and all four lines on the right panel. (Two separate panels at the foot of the bed with a 50 amp "main breaker."
 
I did the check after turning the circuit breaker to my 50 amp shore power plug back on. While doing these checks the PLM output for my line 2 remained at 167 volts. Sounds like I better be giving Flight Systems a call.
 
Anybody got any other things I should check?
 
Thanks,

Mine was showing very high voltage too on one leg. 1 on the other, then 1 on both legs. From searches on the forum I found Flight Systems. Other members had similar issues and used Flight Systems to do the repair.

Trent, my voltage readings went way high one day, kind of scary. Read the same on generator or landline. Tested voltages with the DVM.  About 120 where expected.  The problem did not go away until I removed the panel so that I could install two new panel mounted volt meters.  I had to unplug the line monitor from the duplex outlet.  When I plugged them back in they read back in the 120 range.  Simple fix with no reason why it worked but it did.  Did you try this?

Line monitor reads about 2 volts more than the DVM which reads about 2 volts more than the two new panel meters.  They are all adjustable but which is more accurate?  Fine as is. More cool lights to impress visitors.

I have a couple of these, they give no voltage information but they do help detecting with wiring errors. They only tell you about polarity on the leg that the outlet you plug it into is connected to.  Find an outlet on each leg and check them both.

Roger,
 
No, but I definitely will tomorrow.

This is the same as our home-made inexpensive RV electric hookup checker.  We use it before every hookup.  It also lets us know our 50-amp outlet is 220-volts or just the same 110-volt leg.
This month we are plugged into a campground 50-amp outlet that is not 220-volts.  Both 50-amp breakers must be cabled to the same underground hot wire.  Voltages are good and our neutral will not be overloaded if we keep our total coach load below 50 amps, which is quite easy for us.
