Two, I wanted to bypass the internal “exciter” setting built into the alternator. Typically, the alternator “excites” or turns on around 800 rpm. While that’s not normally an issue, I encountered an unforeseen electrical gremlin that caused the truck be unresponsive until the rpms were brought up high enough for the alternator to “excite”. With 12 volts at the coil during cranking and once it fired, I was at a loss as to why it ran this way but it was totally unresponsive until the alternator excited. This often required some careful “finessing” of the throttle until the engine came to life. Once I wired it this way so that the alternator “turned on” with 12V switched power, the problem went away. If there’s any electrical gurus out there who can solve this, shoot me an email and I’ll publish the answer and send you some CCT swag!
