How do I test for battery drain?
My bike’s battery is draining when I’m not using it, which I suspect is due to the alarm. I thought I’d disconnect it for a period and see if that is the cause but I don’t want to leave it unprotected for an extended period. How do I test for battery drain quickly? Barry Carter, email Answered by A Chris Dabbs, MCN You need either an ammeter or a multimeter set on amps. Take the negative lead off the battery and put the positive lead from the ammeter onto that lead, then put the negative lead from the ammeter on the negative post on the battery so that it forms a circuit but do NOT switch the bike’s ignition on during this period. The alarm manual will state the drain, so you can see if it is that or something else.
Alarms sometimes mask other faults
