We have a 1996 Ford F150 that we use as a utility vehicle. It is started only when it is needed. We had a battery die on it and we figured that it was just because of age. Then we had the new batter die on us too. We know that no lights are draining the batter while it is not running. The only thing that we can suspect is the after market car alarm is slowly discharging the battery.

Any idea how to cut the current going to the alarm?
