help pioneer ct-1250 doesn't rewind !

[Philgou]

My pionner deck ct-1250 doesn't want to rewind

green lamp under the button is working, solenoid ' clicks" but the motor drive doesn't turn backwards

play and forward works great

so where to look ?
('seems there is not voltage on the motor in rewinding position) ,

any advice helpful

sory for my bad english

Mesure voltage on the motor when rewinding. It should give you a clear indication on what's wrong. I would say it's the driver circuit. I've seen that circuit explained somewhere in internet with comments on how it works. I reverses de voltage go get the motor running backwards.

The motor doesn't rewind, it's done through the idlers which have a rubber replaceable band (tire) around them. There's also a idler pulley that wears out also. Replace them and you should be good to go unless the clutch is cracked. I bet fast forward doesn't work either. http://www.wjoe.com/vintageandantiques.htm#CTF series Also the model # is CT-F1250, just for clarification.
