Hi, just signed up, I am trying to repair a Coinco Lower Logic Board P/No 903037 rev 7 and there is a zener diode marked DZ7 609 for which I can find no info, is it 9 volts? supply to board is 18v ac then via a bridge rectifier and zener to the board's circuitry.
I am also trying to draw a schematic but am getting a headache, anyone out there have a schematic already?
The coin changer is out of a Dixie Narco vending machine, the whole coin changer is S75-9800A and the repair manual (available online) was printed July 1988 but does not go into circuit board level.
Help would be most welcome
PS I posted this in Manuals and schematics but Forum advice was to post it here so now it's in twice
