Charging flat battery / Alarm issue

Postby vmx1200 » Wed Dec 12, 2018 10:26 am

My friend has and R nine T that has a factory fitted alarm, he hasn't been able to use the bike for a while and the battery has gone completely flat.

I offered to put it on charge for him so removed the seat to get to the remote battery posts however on connecting the charger the alarm goes off, I am sure there is a simple way to stop this happening .... but I don't know what it is :oops:

This is probably the alarm recognising low battery when you try to charge.

Plug charger in and turn off alarm using the fob.

Depending on the alarm, if you hold down the arm or disarm button for 5-15seconds this normally puts it in service mode and typically beeps to let you know

Thanks for the reply, the bike do not have a fob and is controlled via the left control buttons however the battery was so flat the LED info screen did not illuminate

Eventually we just left the Accumate attached directly to the charging post (the CAN bus did not recognise it) and put a couple of duvets over the alarm box, once the Accumate had gone through a number of test cycles and the alarm had gone though a number of activations the battery finally charged
