Short Version of Story:
I got a Kenwood deck, EQ, and AMP. The EQ and AMP are 20 years old but work and worked before I dropped it off at the body shop. I am getting power to the radio, but no radio number display in the radio LCD screen or sound.
Longer Version of Story:
I got my car back finally last week. The first thing I did when I got in, was turned on my radio. No go. (my dome light was off as well) It was late on Friday so I figured I'll work on it next morning. I got power to it by tightening the neg wire to the dash ground screw the following Sat. But no sound or pop to the amp.
This past Sat I took a closer look and noticed the red wires were tapped into an orange wire. I know based on my search here, that is not correct, and when it was installed they should have used the original radio harness or tapped right into the fuse block. Yet it still works. It was a bit of a mess so I cleaned up the connections with T taps and butt connected the orange wire. After that was all done, I am at the same point, but now no radio number display on the screen.
With installing T taps, I am able to take out each component to help rule out the cause. I took out the EQ and that made no difference. I also played a cassette tape and I got no sound. The amp is getting power and with my limited electrical skills with a voltmeter, I think that is true. I got the pop when it came on.
What the hell could it be? The dome light is still not working and I am thinking it is related somehow? They replaced the windshield so they messed with the antenna cable, but that would not effect me playing a cassette.
Any suggestions? I checked the obvious, in-line fuse from the radio on the red wire, in-line fuse from the radio on the yellow wire, and the in-line fuse from the amp, and any fuses on the fuse block. The ground wires look good. One ground wire was spliced onto another ground wire which I removed and wired directly. There are 3 grounds. The only item that may be 'wrong' is when I butt connected the orange wire, I did not strip the wire, not sure if I needed to strip a wire for a butt connection? All the other wires were stripped at 1/8 length.
I even took the red wire from the radio and connected to the original yellow wire for the radio, same results.
Thanks in advance.
