Finally got around to installing my Steel Mate alarm that we got as a group buy here in Sydney. I didn't bother with the immobiliser, the LED, blinkers flashing or anything else - just the black and red wires direct to the battery and of course the siren. I taped all the exposed wire ends from the big bunch coming out of the controller. There was a single, much shorter, black wire coming out of the controller unit (not with the big bunch of wires) with a pre-soldered "O" end on it and I just earthed this to the bike - anyone tell me what this wire does or is supposed to do?? All worked fine yesterday and all set to go for a quick ride this morning but absolutely zero battery when I went to turn alarm off and pushed started button. Many thanks in advance.
