Alarm removed... at last!
Ped extracts an unwanted alarm from a mass of bike wiring
ith last month’s handling issues sorted (as originally suspected, I’d just nipped up the head bearings too tight) there was one more job I’d been itching to do on the Blade, and that was to remove the alarm.
I’ve nothing against alarms, except that no-one takes any notice of them, they usually go wrong at the most inconvenient moment and the beeping when arming and disarming is so loud and so high pitched it sends nextdoor’s dog up the wall. It had to come off.
I’ve removed alarms from used bikes before and while the mass of wires can look daunting, it’s a fairly simple task.
Carefully slicing back the insulation tape from where the unit joins the bike’s wiring loom, I quickly found the two wires that carried power to the alarm – a permanent live feed and a switched live from the ignition. These were both close to the battery and show how the alarm’s wiring interrupts the circuit.
Cutting back a second bundle of wires revealed a feed for the indicators, lights and two other wires. As with the power wires, you can usually see where an alarm has been piggy-backed into the loom to make the indicators and lights flash but I couldn’t work out what the two rogue wires were for.
A successful web search for a workshop manual wiring diagram revealed that there had originally been a blanked-off six-pin connector in the loom. It was marked on the diagram as OP, presumably for Output.
As well as the indicators and lights, this plug also included an earth and a switched live, all of which were utilised by the person that fitted
the alarm. Mystery solved. I could now safely remove the alarm from the bike, reconnect the necessary wires and isolate the others, checking each step of the way with a meter and finally connect up the battery.
As much as I dislike working with bike electrics, such ‘eureka’ moments are always supremely satisfying and the bike is one step closer to being returned to standard.
