Bottles won't release

I hope someone can help because I don't know too much about these machines.  I have a cs-80 machine and all of a sudden, last night after putting in the quarter the bottles won't release.  The quarter goes through the coin mechanism like it should, but it doesn't make the "click" noise like it used to to release the bottle.  Everything has worked fine for the last 12 years and all of a sudden this happened.  Thanks in advance for your help.

Hmmm.... Sounds like your coin mechs. pricing logic went south for the winter! is it a coinco unit & what models mech?

The brand is Coin Acceptors, Inc.  The model number is FP800-807.  I hope that helps.  Thanks

OK, I'm working on digging up a manual for that model.

Boman, I've got a copy of the FP9800 manual, (don't know if you got my P.M. I sent to you) I states that if the stepper fails to supply a vend pulse to the vendor, (pin #7 of the jones socket)then the vend or price switch are defective, or the interrupter switch may be misadjusted or defective also, if you have a fax I could send you a copy  of the  manual...JohnieG
