[QUOTE="Perplexed, post: 3835973, member: 7157"] Ok, I have yet another fire alarm bell, and I’m learning about these things as I go… In this case, the wiring scheme is new to me, with multiple wires going to various parts of the rig. In the pic below, I’ve circled in yellow an item that I find odd. One of the leads goes to one of the incoming power leads, and the other lead is soldered to a black wire that goes up to the underside of the electromagnetic coils, but I have yet to remove the coils to find out exactly where. Before I futz with the layout though, I’d like to know what the item is. It appears to be a capacitor based on the markings (which are the only ones on this item), but I can’t see why the alarm would need one. I get “OL” on a multimeter when trying to measure resistance between the two leads coming out of the item. Anyone have any tips on what it is? [ATTACH type="full"]293396[/ATTACH] [/QUOTE]
