Hey people a friends car his cd player shorted out sometime ago
so we put another deck in there. Now originally we thought it may have just been his wiring.

so anyway we wired up another one last night old car very basic wireing. so there was one wire from the positive of battery direct to the memory wire of deck. then the access wire from deck went to the positve of the cig lighter plug.

the earth went to the battery also directly from deck.

speakers are wired direct with new wireing not using anything from facotry harness.

Now with ignition on everything was working great no problems at all turned it off and on fine. As soon as he turned the engine on big puff of smoke came from the deck again.

I put a multimeter on the wires with engine running and on startup no mroe than 14volts was pumping through. So i couldnt see any spikes or the likes
also if its working normally with acces and ignition then there cant be a short i would have thought. but when engine started blew deck up.

any ideas or anything to look at please


thanks

Tim
