Frank, thank you kindly for the time and explanation of the system.
Everything makes sense in what you said, but what I’m not getting now
is regarding the Safety Switch and how if prevents starts at “above start”
throttle settings.
If the Vacuum switch is “normally open”, how is the safety switch preventing
starts at high throttle positions? I don’t see how it could ground out either coil.
Thanks.
Prepare to be boarded!
