Question about Alpine CDA-7863 CD Player
My only suggestion is to check your wiring.
Be positive your accessory wire [red wire] is hooked up to the correct wire from your car's wiring harness.
To be positive this is the problem, connect both the red and yellow wires [accessory and battery] coming from your head unit to the battery wire from the car's harness temporarily.
Do not, however, leave your head unit wired this way. It will never shut off and drain your battery.
If your head unit still does not turn on, and you say the fuse is good, you most likely have a bad head unit.
Most head units now have a fuse in the back next to the wiring harness as well.
Don't forget to check that one as well, in case you missed it.
