I just installed a AIWA CD-R418 Unit to a 95 Nissan Micra. after i install the HU, the HU seems become a main witch of the car electronic system. ( when i turn on the HU, the blower, screen wiper can turn on.) but the fuse of the side lights and instructment panal lights gone. and after i replace the fuse, and it immediately gone again. and my car is installed with a Toad immobilizer.

now, i can only unplug the HU, then can the side lights be turn on.

any gurus please help or give some suggestion on this problem. thanks.

Being completely unfamiliar with your car, I can only guess you shorted to ground something during your install.

sounds like you've got a dimmer lead hooked up incorrectly as a speaker wire or ground.... disconnect the radio plug and meter each wire for voltage with and without the dash lights on.... you'll find a wire that has 12 volts when the lights are on and 0 volts when off... make sure this wire is not connected to anything or is only connected as a dimmer / illumination wire.....

The black wire from the Head unit needs to be grounded. Look at the sticky in this forum for "what is a proper ground"

Actually Never Mind.

You basically need to get that black wire to some bare metal that is part of vehicles chassis. this completes the cicuit for the Head unit. I"m suprised you said its working without this wire connected.

Under your dash should be some metal / plastic / screws etc. Find a convinient place to get the black wire to part of the metal. Either drill a new hole and use a metal screw and ring connector on the end of the wire or find an exising screw you can back off and run the wire there with a ring connector. Make sure either way that its part of the vehicles chassis somehow and always sand rust and paint off to get bare clean metal.

Your antenna provides a ground- that's why it's working. You should still run the ground wire to a true ground.
