Is my alarm/immobiliser causing a parasitic drain?

[squibb34]

I've just removed the tracker and left the sub-loom and antenna tucked away.

I have no idea how to change the alarm to manual and sounder style.

I'm not sure why one would leave the tracker loom in place but I guess, if the alarm (DWA) still functions correctly it shouldn't be a problem.

The rider's manual for your bike is available here ......... https://www.bmwmotorcycles.com/en/service/manuals/rider-manual.html#/section-further-manuals

Just page down to your bike's 4 digit model code. Somewhere in chapter 4, around page 87 - 93? will be the full explanation of the DWA system & how to personalise it's operation.
