Removal of faulty alarm.

[EasyGoingPat]

Hi,

I have a BMW R1100S fitted with a Spyball alarm and an immobiliser. At the weekend, it developed a fault and left me waiting for the RAC truck.

The bike is getting on a bit in years, and I am thinking of simply removing the alarm and not fitting a replacement. Does anyone know if this is likely to be a job that I could do myself? I can follow a wiring diagram (not that I have one for the actual alarm), and I am competent at basic motorcycle work.

On a related note, does anyone know if the immobiliser is part of the Spyball or was fitted to this bike by BMW as standard? If the latter, then I am guessing that removal is not an easy thing to do.


Kind wishes ~ Patrick

You could ask this outfit for some advice. They helped me remove a Meta immobiliser, by supplying a hand made bypass plug for £35. Works perfectly.

I'm pretty sure the BMW will have a factory immobiliser fitted as standard, but the SpyBall has one too - so you really need a wiring diagram to see how it is connected.

Fitting a new battery (in the fob) and re-syncing the alarm might fix the problem.

If you know the model number, you can download a manual from Here.

Hi, I've removed alarms/immobilisers from two bikes now and as long as you're methodical it's not difficult. Assuming it's not a simple plug in job just cut back the tape and follow the (commonly all black) alarm wires back to where they join the main loom , you'll see where the ignition and starter wire have been cut and simply rejoin them.
If your particularly smart you can wire in a hidden switch to act as a manual immobiliser and add a flashing led.

EDIT: this all assumes it's an old bike with conventional wiring and none of that CANBUS nonsense.

I took an alarm off a R1100s a year ago it was a right pain

Alarm was under the seat and the loom had been opened right back to under the eat alarm wires added and re taped up


Just take your time open up as much loom as you need to find the ends of the alarms all black wires and use soldered joins to make good the breaks in the loom
Don't re tape the loom until the bike has been proven to start!!

No factory immobiliser on the R1100S, the alarm does have one integral though.

I assume it's a Spyball Patriot Am 8510 since that's the only spyball one of the era that insurers discount for AFAIK. If that's the case just follow all the wires from the alarm to where they attach in the loom. You'll have power (with a fuse holder), ground, switched live (I think, been 5 years since I removed mine), indicators, aerial and one or two immobiliser circuits. Depending on how it was fitted you might find that they have just popped the insulation and soldered into a loom wire without cutting it. For the immobiliser circuit they would have cut the wire so just re-join like colours.
