battery drain on 89
I just bought a 89 Coupe, I also just had a alarm and keyless entry system installed. The battery seems to completely drain with 4 or 5 days, whether the alarm is on or not. The battery was new in Nov. 07. Any thoughts on what is killing my battery or how I can find the culprit.
thanks

Having the battery tested, would be first on my list.
Finding the circuit that's draining should help narrow down the culprit. Pull the neg battery cable and put your meter leads between the post and cable(set to read amps). See how much current drain you start with, then start pulling fuses till you remove the large drain. When you do this, tape the door switch closed so your not running the courtesy lights.
