I pulled out my IH shop manual and my Chiltons Truck and Van repair for
1971-1978 books. The IH manual says the resistor is there to protect the
points from having to pass 12V under normal run conditions. The by-pass
is there to allow TWELVE VOLTS to the coil at start up especially in
cold weather. My Chiltons (I'm sure this is in the IH manual to I just
didn't look for it until I opened the Chitons) says that the external
resister is a .43 Ohms resister. If you do the math then you find that
V*Ohms=lost V or what is left after the resistance has been powered.
Therefore 12*.43=5.6V That is where the 5V at run comes from.
