I have an '05 LS185.b that all of a sudden stopped working electrically. Turned out to be a plug-in diode located inside the main fuse box. It is black rubber and looks sort of like a 2-wire trailer hitch connector. I beleive there are two diodes in the fuse box. I keep a spare diode zip-tied to the wire harness next to the one that blew. New ones are $15 each. BTW when this happened in Oct of '05 this machine was trained-on by NH technicians. It took the dealer a week to find the problem with NH Technical's assistance. Hopefully dealers have been trained by now :)
