Cadillac Repair/86 sedan deville fuse box


So i have a 1986 cadillac deville sedan i just installed an aftermarket stereo i bought a harness and kit for it i installed all the colors accordingly i only had a blue wire which was power anttena and a orange which is illumination the stereo worked and everything but then it shut off and my digital fuel gauge and a/c gauges arent working all my fuses under my dash are working i checked with my fuse tester cant figure out whats wrong please help.


It sounds like a gauge fuse blew and for some reason it appear that the stereo is somehow hooked into that circuit.
You need to find another ignition power source.
As for the fuses look at the owners manual to see if there is another fuse box under the hood.

I am wondering if you located another fuse box under the hood?

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?
