Question:

Wiring harness fault?

Basically over about a four month period the radio/cd player in my truck was going on and off. It would work sometimes randomly, but now it is completely dead. I changed all the fuses and that isn't where the issue is. I have the original radio and I don't really want to replace it. I feel like if the fault were in the radio itself, it would have simply gone dead and not worked. I am just wondering if this has happened to anyone else, or if anyone has any advice about what the cause could be? The truck itself is 17 years old, so it's a possibility that over time a wire came loose, or even for the radio to die. It came with a 5 cd changer that is in the cab, and I noticed at the very beginning before it starting cutting on and off that it would say that it couldn't read cd's. That was probably a few days prior, and then when the radio did actually work, the same problem persisted. What do you think the problem is?

Answer:

You answered your question, you have a 17 year old electronic device, in probably in the worst environment ever. The heat/cold, vibrations, everything included in a vehicle's use, are the enemy of electronics. The good part is, even with an older vehicle, you can still add an aftermarket radio, and still take it with you when you get a new vehicle. Good Luck!!
I use a Multi-Tester (Volt-OHM-AMP) meter. I check each wire--for continuity. I also decide on the ground.(common ground).or a direct ground at the 12-volt battery./ I like to use a direct wire--from the 12-volt battery./with a in-line fuse/ I most times use the cigaretter/plug-in as my ground point./ Or I even run a ground wire back to the 12-volt battery./ The radio may have been running hot.and you placed wires at a terrible location./ (re-check the installation) If this is a automobile application--the 5 disk CD Player--will have Shock/detection/protection. Or.you may only be able to use store bought--CD's. NOT--ones you made on your computer. Try that. See if store bought CD's work better./ Most radio applications have fuses--that are very difficult to inspect--without a magnifying glass. I use 10-AMP for such things./
