vendo 216a problem

[texas]

Hi

I would need help to figure this out since I'm new at this...I'm almost done with my vendo 216a project but when I turn the power on the machine the roll's start moving from left to right and so on...they never stop ! I figured it was the cam motor switch that was broken but I wanted some advise on this

thank you

A quick review of my V-144 electrical diagram shows the Vend Relay may be staying energized or the Motor Cam Switch is not functioning.
Based on what you stated, you need to see why the Vend Relay is staying energized...
