I've had a battery drain for 5-6 years. Never really bothered me because i seldom drive it. I have a quick disconnect for the terminal i use.. Well after 5-6 years of procrastination i disconnected ( aka- cut the wire ) to the alarm today. Hopefully that was the problem. I'll let you know in a week. I really don''t feel i need the alarm since I've lived without for soo long. Not sure why people bother replacing them??
