73 135 Wiring ?

[Bunky]

Does someone have a wiring Diagram for a 1973 135 engine ? When I got my engine someone had removed the starboard side head and clipped the wire going to the Sensor or what ever is in the head, and I want to make sure I have things put back the way there were,

I also don't have spark on all 4 cylinder is this possible cause ?

The brown wire goes to the temperature switch in the head. (one on this engine). If the knife connector is missing, you may be able to splice the line and put some heat shrink over it. The loose wire end on this overheat circuit should not affect the ignition system spark. You will have to look at the ignition components for the no spark problem. A factory manual will be helpful to diagnose your problem. Not only does it have electronic troubleshooting, but it has a color wiring diagram in the back of the book.
