Un hook the radio and harness. take the red and yellow wire and hook them together. take a jumper wire hook the ground and the red and yellow to a battery and see if it will turn on that way if not the you have a bad radio.

Yes it does you interuptted a power supply. You basically need to get another power B+ from a different source like the battery itself. Or a empty fuse slot. Becareful even with a common ground for cruise and speed gauge.

My Pioneer DEH-P4200UB Won't power up in my 97 mustang gt. The car recently had a kenwood deck that we took out. we are still using the kenwoods wires. Help us lol


Please verify voltage at the constant (Yellow) wire With the ignition OFF
Then Turn the Key to ACC and verify voltage on the RED wire.
Double check the ground to chassis metal.

The radio should power on at this point if both power wires show 10-14.4VDC
If not - your radio needs repair.

I have a 1990 Celica, trying to put in new radio. Got everything wired up correctly, Constant - blue/yellow, acc - gray, ground - brown and it won't come on. Radio fuse (top center 15 amp) is good,...

You have it right. Use a 12 volt test light to see if there is power between the gray and brown wires when the key is on. If there is power there, you may have got hold of a bad radio.

How do I wire this radio into my boat? The wires coming out of the harness are one red accessory/switch, one black ground, one yellow constant power, and a blue power antenna.

Red goes to the battery.
Since this is a boat, the yellow will go to the battery too, but I recommend you put a toggle switch on this wire, so you can turn it off and it won't drain you battery. The black wire goes to the ground on your battery. The blue wire can be used as a remote turn on for an amplifier.

Thats' It.

My house lost it's ground when we had an electrical problem. Now my BOSE won't even turn on. Is there a reset button or a way I can get it to power up again?

when you lose your house ground/neutral connection,the system becomes a voltage divider type system between two appliances on each phase,and say a 1000watt appliance on one side and your bose on the other at say 20 watts,the lower wattage appliance will experience say a voltage of 170volts and the 1000watt will receive only about 60volts,you may have lucked out and only have blown an internal fuse or the radio could be shot
