Office of Steam Forum for Model & Toy Steam Gas & Hot Air Engines

I've attached an image of the sensor with the colors of the wires as they should coordinate. Take note of the writing on the chip facing up when wiring. Also not sure how this engine is timed, I don't think the chip went all the way into the plastic cover that holds it on the cam gear, so it will be a little retarded (or advanced?) from normal. This was because I used a waterproof heat shrink tube to cover it all, and that added a bit of extra thickness. Won't know if it is an issue til I fire it up!
