I burned out this little resistor? diode? which was installed in a green wire between the ac panel power switch and the ac ground bus where the polarity indicator is grounded. The archives have a discussion of this little bugger from back in 07, and the concensus was if you can't find it, don't sweat it. Well, I can't find it, but would really like to install one or a suitable substitute since I just don't think Hunter was into putting extra work/parts into their panel wiring [which is not too impressive to begin with as OEM did not use any shrink tubing at all and many spade connectors].
