Polarity Indicator Light

Iím asking all my reference colleagues to help with a small problem I am having with my 120 volt panel. I installed an electrical panel, 30amp, 120 volts 60 Hz, with 4 X 15amp and 1 X20 amp circuit breakers. The installation was done according to the instructions on the panel. (The panel was pre-wired from the factory.) Once I was done, I plugged in the shore power cord and noticed the polarity indicator light was on very low. When I used the polarity test toggle switch the light glowed bright RED. When I released the switch, the polarity indicator went back to a low glow (almost indicating that there was a small leak of power across the neutral cable). I checked all ground and neutral outlets to make sure that electricity was not leaking. All outlets registered 0 on the meter. Once I turned on the main breaker, the mellow glow disappeared, all outlets worked fine, and there was no current running to any metal objects. I have checked all the wiring from the dock to the panel and everything is in compliance with ABYC E-11 standards. What would cause the polarity indicator to glow extremely low with the main circuit breaker off and go out when the main is turned on?

There is a tech note on the Blueseas site covering false fault indications for reverse polarity
