Well, specifically the problem is this: the customer brought his boat in for general Pac Cup prep, including replacement of the Aqua Sig 40 Tri-Color incandescent lamps with Led's...brand unknown for the moment. While the mast was down I checked all lamps on the mast and all were good.
Upon reconnecting however, I discovered that I had inadvertently gotten my color coding screwed up...would not be a problem if the lamps were incandescent...I could just figure out which was the ground conductor..more difficult than it seems by checking the respective resistances of the Anchor (10 watt) and Tricolor (25 watt) lamps and go from there. The issue is complicated by the presence of a Strobe. The Tri seems to be connected properly and can easily be seen. It draws 140 ma. The Anchor can't be seen at all (it's drowned by bright ambient light) draws 40 ma. My question is: is the 40 ma draw reasonable for the 10 watt? I think it is, and have concluded (inferred) that is working.
Pulling the rig again is not a viable option.
Any ideas??
