1989 c1500 remote start
hey guys. i just installed a remote start/alarm in my 89 c1500 3 days ago. now heres the problem. when i remote start it, the battery is not getting charged, so that the next time i try to start the truck,(remote or key) it wont start.(ive been stranded 3 times and had to get a jump). ive had the truck 3 months and i never had a problem with the battery(new) or alternator. so my question is what could be causing the battery to drain with the remote start and not when i start it with the key.other then the wiring(i had the alarm guys check it 3 times). im running out of options and i wanted to see if you guys had some ideas before i take it out of town. theres not alot car alarm shops in my town. sorry this was long, just tryin to make sense. any help is greatly appreciated!!! thanks guys!!

Re: 1989 c1500 remote start
First- see if your alternator is charging properly- with a votmeter- on battery- does it produce 13 or more voltage with engine running? as well as with engine running when remote started? if so-- continue below..
Sounds like your alarm is draining your battery- from relays that are always energized-- to test: pull all remotes start/alarm fuses-- does truck start the next morning? this will tell you the alarm is the problem or not-- If truck started above- then do a battery draw test- put a DVM (digital volt meter) in amps mode and between your battery and the battery hot wire- if it pulls more than 50 ma after about 10 minutes- then this is the drain that is killing your battery-- next pull the alarm fuses- see if drain drops down to about 20 ma- if so - this is the cause- the alarm- If alarm is the cause- look for relays that energize (click) when the alarm fuses are plugged in- if so then the alarm install is wrong- relays should not be energized while the car is off and sitting for awhile- this creates battery drain. you probably have a starter interrupt relay- this may be wired wrong and creating the draw.....let us know....
