About Rob Painter
Expertise
Alarm system questions cannot be answered on this forum. These systems are not what I can answer. Without being physically at the vehicle and not knowing what kind of electrical service has been done on the vehicle, there is no possible way to give an accurate answer over the internet. My expertise is in Ignition/key based anti-theft systems. These issues include GM VATS (resistor chip in key blade) PASSLOCK (MRD)-ignition lock rotation based, no special ignition key and the PKIII Transponder (computer chip in key) systems. These systems are not alarm based and are integral with the starting of the engine. This is why I cannot diagnose alarm problems without physically looking at the vehicle: Alarm systems are a completely different annimal than ignition key/lock based anti-theft system. Many alarm questions come from vehicles 10 years old, and since older, many hands that had been involved over the years.I am an expert in all GM factory (ignition/key based)systems. Alarm system questions pose to many situations beyond my knowledge as to what has been done to the vehicle over the years. Some guy may have actually wired the stereo into the alarm system. Who knows? Over my past 30 years in vehicle wiring repair, I have seen unbelievable wiring disaters done by guys that consider themselves "mechanics." I have seen stereos and alarms intalled using surgical tape. I have seen modules burn up, un-fused circuits, wiring jambed between the doors and even lamp cord used for a starter kill. To answer alarm questions over the internet without examining the vehicle is like asking; What does it take to remove a dent?

Question
Security Light on dash board does not go off after shutting down the engine. It continues to remain on and drains the battery (which I have had to replace). Q: Please advise as to the repair. I keep the vehicle in good repair; this just happened. Will it be a "involved" situation to have it repaired... or is there something I can do. Thanks in all cases for being there. s/ Rob.

Answer
Hi Rob,

The best I can tell you is go to alldata.com and pay the $30 for membership. Type in the exact vehicle you have and you will get everything you need to know about all the wiring, all the circuits and much more. I don't get compensated for endorsement, but you will soon see why it is the best source for repair out there.

Good Luck!

Rob
