Mazya Dynamite Kid's Token Sensor problem

[wkmiller]

My Mazya Dynamite Kid's is giving a 1 E error which goes away if I unplug the Token sensor board.

Sensor board has 4 wires going to it.


On the back of the board it has MZY-304-02 Matsuya


I tried to goggle the part number but got no rersults.


I checked the components :
4 visible diodes on the board , all only allow one way continuity as they are supposed to.
2 Resisitors show expected 330 Ohms.


Which leaves the 4 Capacitors and Optocoupler.


Electolytic Capacitor looks fine, has no sign of leakage or bulging.


Optocouple has: P1018 00: and a backwords looking E Symbol


Googling showed no results for thepart#


Any suggestions on further troubleshooting?
