Quoted from iamabearsfan:A long time ago I purchased a 3rd magnet kit. Came with Optos.
The problem I have now is I am not positive which wire is the Kathode/Anode and Emitter/Collector.
Based on these pix, they are marked, but not used. Thoughts? Should I assume Green = Kathode and Gray = Collector?
Don't want to assume on this one
