Aftermarket Kenwood Deck non responsive

[Harbinger]

Deck won't power on. Wondering how I should tackle this issue. I'm really hoping its just a wiring issue otherwise I'm royally fucked.

Fuse?

Did you just install it? 12v trigger wire connected?

With key on, check for constant power / check trigger wire. If both ok, not so good.

Was installed a year ago. What's a 12v trigger wire?

The trigger wire is usually blue. It is set to a keyed 12v source, usually ignition. Regular power should come from battery and will have an inline fuse. 12v trigger sends a signal to radio saying key is on and now you can turn on. If you have no power at all to the radio, check the red power wire for an inline fuse, may be under the hood. Check the connection at the battery too.

But you can pull the deck out and check for power at the red wire with key off. Check the blue wire with the key off, should be no power, key on, should get you power.

Blue wire is an output from the Deck......

You need constant power on the Yellow wire.
Switched power on the red wire.
Blue wire (and Blue/wht wire) are used to turn on external amps and extend your power antenna.

Thanks for the information. I'm not very versed in car electronics but I'm a quick learner. I'll keep everyone posted on the progress

There is also an inline fuse from +12V (red wire) and also behind the deck there maybe a fuse as well. Check both if applicable. Also check to make sure no wires were pinched when the deck was installed as this could be the cause for a blown fuse if it applies. The harness could have come off as that is quite common as well.

Thanks scrape. I'll check everything. I'm just hoping it's a loose wire or fuse rather than the deck biting the dust

I stand corrected...yes, the blue wire is switched output wire...
