you will need the red and the yellow connected

one is a permanent live, the other is the switched live.

does the cd player work?? may sound silly but

ive connected the red to the yellow which still works the "cd"player,but there is no display and no sound,im thinking with the stereo being in the shed for nearly 8 month,it could of gained condensation etc,im saying this as ive just used my original cassete player out the nova which has been in the wardrobe upstair's for 4 year's and works, display, sound everything!??.would you agree its time for the hammer!

if its a kenwood mask i think there is a break in the flat ribbon that joins the face back plate to the stereo.

well ive been searching ebay and there's quite a few nice one's on there for very little mone,y so im probaly going to go for one of these.

nip down to our place andy when you can, ill sort you one out :thumb:

cheer's davey boy!ive just got in now and while ive been out one of the lads has given me a sony player so ill try that if that dont worklolill nip down:thumb: anyhows i got the van now for getting the larger nova parts out the scrappy lol:thumb:
