BLAUPUNKT KOLN AUTO TUNING

[francozappa]

Hello to everyone. I'm repairing a Blaupunkt radio mod. KOLN series X. I have the wiring diagram of the model V, but it seems different. The radio receives on all ranges. The main problem: it does not work auto tuning, the motor does not turn and pressing the tuning button something goes shorted. Does anyone have any suggestions for me? Thanks a lot to everyone.

I would suggest that either the motor or the wiring to it is shorted out.

Try connecting the motor to 12v (briefly) and see if it turns or if it just creates lots of sparks.

Dave.

Good morning Dave. Thank you for the replay.
I did some tests on the radio and the wire links were not perfect.
Now the radio receives on all ranges, but auto tuning AUTOMAT works only on K range, where it receives only one strong enough station; on the other ranges the motor always runs and never stops.
I think the problem is adjustment and alignment of AUTOMAT. I have the wiring diagram and service report of the model V, but it seems different from model Y.
Do anyone know where I can find the schematic and service manual of KOLN model Y ?
Thank you so much
