I replaced my 5 year old JVC cassette tape AM/FM receiver with a new JVC CD player and AM/FM receiver. The wiring harnes from the old one just popped out and fitted perfectly into the new one. Installation was less than 3 minutes. Here's the rub. Only one speaker in the cockpit works. The two in the cabin work fine and produce nice stereo sound. When I adjust the right/left balance, I can make the cabin speakers play only from the speaker I pick or, of course, both speakers when properly balanced. I can't do that with the cockpit speakers. Only the one speaker will play. I took the other speaker out and hooked it in the cabin and it works just fine so we know the speaker itself is okay. I can't see any break in the wiring but, of course, I can't see that far. Any idea what might be causing this and how I could check it out? Thanks fellas.

Speaker Testing
Rick, You want to test everything from the stereo to the speaker in one shot - Use a 1.5 volt AA or D cell and connect (just flick it, actually) the two speaker wires briefly to the battery. A good speaker will produce a click. You might want an assistant to listen. Since you've tested the speaker, it's the wiring if there's no click. Did all four speakers work with the old stereo? You didn't mention the fader control. Be sure you have only cockpit speakers when faded one way and only cabin speakers when faded the other way. When you fade to the cockpit, then run the balance back and forth. You should have left/right sound. The same is true for the cabin speakers. Stereos have four speakers, generally: Left Front, Right Front, Left Rear and Right Rear The fronts are on one end of the fader control and the rears are on the opposite end. I would install it so cabin is front and cockpit is rear but either way works. Don't ground any speaker wires. Modern stereos supply their own return wires - or should. Let me know if this helps...

Get a VOM
Volt Ohm Meter at an electronics store and measure the resistance in the wires. My guess is that you will need to pull a new cable. You might want to take a good look at what caused it to break and fix that too if you can find where it failed.

Rick you may want to pull the connector to the stereo again and...
look closely at all pins in it. It sure sounds like one has been pushed out of line. If you pulled on the wires you may have moved a pin to where it won't make contact with the stereo jack. Sometimes it doesn't take much for these to get out of whack. Good luck.

Rick-CD problem
Rick, Had a similar problem that gave me fits for over a year. I replaced my Aiwa am/fm cd player with a Sony. Wires all looked the same as far as color codes but everytime I hooked it up one set of speakers would fail and I would get static and a display of"cd failure" on the unit. I checked evrything-power sources,speakers,etc. I finally ran some cheap speaker wire independently to each of the speakrs and VOILA they all worked. Now I knew I had a speaker wire problem. Now I had to find out which one. I unhooked one of the good wires and added one of the old wires. By process of elimination I found the bad run. I don't know if they just got corroded over time or it was the way the previous owner had them wired. Paul H S/V Linda Belle 95 H26

Thanks Guys
I really appreciate the suggestions. I was afraid it might be a bad wire. I can't imagine what a headache it's going to be trying to pull a new wire. Before doing that, I'll test the existing wires and may even try to hook up the old stereo to see if the speaker works. It sure used to. I hope it's as simple as a bent pin. I doubt I'll be lucky enough. When I finally find the solution, I'll post it so you'll know the rest of the story. Thanks again.

Rick-Couple of additional notes
Rick, The previous owner had the return wires for two of the speakers joined together due to the limited amount of wires in the hanging case.The positive wires were done individually. I separated the return wires and ran them singularly.This might have been the problem all along. Hummm!!! Also, I was real bummed out with the thought of having to rerun all my speaker wires. As it turned out I only had to run one set. I used some 16 gauge single strand wire that I had bought by mistake as a fish to run the wires from where the existing wires were. Hardly took any time at all to rerun the wire. Good luck. Paul H S/V Linda Belle 95 H26

Rick...one more thing
You said that the new harness plugged right into the old one. Did you review the color coded wires and make sure old is the same as new? The manual should have a schematic of the harness wires.

If the problem is not in the wiring, check
the output at the connector. My wife's car recently had no left channel from the cd exchanger in the trunk... I discovered a cold solder joint where the plug connector solders to the pc board. Such cold joints are very often identified by intermittent service or by intermittently working while jiggling the connector. If handy with a small soldering iron and have good eyes yet or a large magnifier, a reheat of the solder joints on the connector can solve the problem.

Same?
Rick, Double check the wire locations on your old plug and the new unit. Even though the plugs are the same, the wire locations could be different. Just a thought. Bryon
