Question
QUESTION: I have a 1988 Cadillac Allante and I've narrowed my problem down to the Central Power Supply but I can't find the location of the unit to do further testing, can you help?


ANSWER: Hello,

I have an 88' Allante so you are in luck. What are you looking for the power to?

Write me at robpainter@autotheftexpert.com and I will see if I can help you. I have the owner's manual if you don't.

QUESTION: I keep getting my e-mail back saying it can't be delivered to the address you left me. I tried it twice. I don't have an owners manual for this vehicle but I do have Alldata but it doesn't show the location of the central power module. I need to find it so I can test the output because I'm getting intermittent power to the turns, gauges and the info center which all seem to be tied into the central power module according to the diagrams.

Answer
Hello,

What is your complaint that you need to find the central power supply? As I stated. I own one of these puppies and with 62,000 original miles, it has been the best car I have ever owned.

Now, have you found the relay/fuse panel near the ashtray? That has circuit breakers for retained power, top pull down and some other things.

Email me at robo14@aol.com and if I know the problem you have, might be able to help you.

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?
