My jvc KD-G152 car radio/cd player will not power up. both yellow and red feeds are live although the previous owner has taken both these feed wires from one permanant live wire behind the dash.Not sure if this is the problem but cant see why it should unless red wire need to be dead when using reset black wire is correcltly earthed. system will not power up press the display or eject button and system lights up for about 3 seconds then goes dead again Have carried out reset (on off button together with set button but again nothing)system is almost new but cant return under warranty so any suggetions would be most welcome thanks trevor
As a sanity check run a temporary wire directly from the battery positive to the radio. Twist the red and yellow wires together and connect it to the wire from the battery. If this works either your red or yellow wire connection under the dash or to the harness is not hot like you think. Yellow usually goes to a constant 12 volt source (to keep radio memory) and the red wire to 12volts when the ignition is on. In some radios this is reversed. The test I mentioned will determin if the problem is in the wiring or the radio.

I have a JVC-KD-S590. It powers off for no apparent reason. I thought perhaps a short in the wiring.But I saw that one solution was to remove the cable from the battery for several minutes. (reset memory??) I tried it, and it worked--but only for a month. I started the car the other day, and the radio had no power again. Took off battery cable again but no good. Any ideas?
