Thanks for the replies Garry and Frank.
After reading what you say, I see that there is already a ground path
at the Safety Switch.
I tested the switch for continuity this morning, and noted that it’s “made up”
when the switch plunger is pushed in. I assumed the switches design was
so the engine would not start at speeds much higher than “Start”, and perhaps
an evolution of the previous “Mercury Switches”???
That being said, now I don’t understand how the Safety Switch and Vacuum Switch
work together.
I presume the vacuum switch is “normally open” and “closes” at high vacuum occurrences
to prevent the engine from “running away”. ???
Are the two wiring post on the vacuum switch a connection across the internal contacts
when the vacuum switch “closes”. I did not test this switch to learn how it functions.
Will try tomorrow, but I don’t have a vacuum pump.
The fuel saver rod may or may not be set correct. I did not understand it at first until
I discovered that the spring “snapped” the throttle full open once the control arm reached
a certain position. Then I noted that one could “throttle down” some with the magneto
remaining in full advance. Isn’t that the idea???
Frank, it looks like you are correct regarding the kill switch wiring going under the coils,
after reviewing the photo when I finally got the flywheel off……. by destruction. 🙁
Thanks!
Prepare to be boarded!
