MVH-P8200BT won't power on?
 

I just bought a Pioneer MVH-P8200BT and it won't turn on.Connections are all good and I even tried my old Pioneer headunit and it won't turn on as well, It worked before??? I took some readings with the key at acc and the constant 12 volt supply wire was 4.5 v and the Ignition switch 12 volt supply wire was 12.5 v.This is installed in my 92 civic hatchback if that helps. Any help would be great.

Thanks.

you should be getting 12 V on both of those.

It was the fuse under the hood 7.5 amp labeled backup lights,but I looked in the factory manual and the wiring diagram showed the radio blue white constant 12 v goes to it and ya the fuse was blown....so all is good now.Really like the new Pioneer MVH-P8200BT don't miss the cd player at all and the bluetooth works great!

Thanks
