I have a 2019 Tiger 800 XRT and the alarm has totally knackered the battery. (To be fair, it probably needs replacing anyway by now.) At the moment, it's on a permanent trickle charge in my garage, but the battery is so damaged now that even if I ride for about an hour the battery is dead again after about 20 minutes or so and needs a booster shot to restart the engine so I can get home. So I obviously want to replace it, but as soon as I disconnect the battery, it sets the alarm off, even with the alarm in 'ferry mode.' Does anyone know how I disconnect the alarm so that I can change the battery?
