Kenwood head unit turns on then shuts off immediatly?
Friday, April 27, 2012 12:29 PM
I have a 2000 cavalier and just got a whole new system. front, rear, and subs. and the head unit. and that stupid wire harness. but i plugged everything in and wired it all up. then i tried turning it on and the head unit lit up, and the door ajar bell went off. then it shut off and wont come back on.

I've heard this head unit is known for that?
Could it also be a fuse? someone said it may?

you can check the radio fuse in teh dash, and the fuse in the back of the headunit... there might be a reset button?? if its new i'd take it back if you can't figure it out

Yeah i checked the fuses and it wasn't them. I'm guessing it is just a faulty head unit.

you bought the expensive harness to keep door chimes i take it?? Not sure how that one works but I did have to tap a wire in the fuse panel for the acc turn on wire with my $5 harness, sounds like something is hooked up wrong and HU going into a safemode or something or its a faulty HU, If its easy to take out, hook the black wire to ground and the red and yellow to positive and see if it turns on....

This was happening to my old Sony. Bought a Pioneer and swapped it out and it stopped happening.

+1


take the black connect it to ground

yellow and red to 12 volt and see if it turns on.. will at least tell if HU is junk or not
