Steve:
That wire is the equivalent of a ballast resistor on other cars. When
the engine is running this wire supplies the + voltage to the coil. The
length of the wire gives it a high resistance, so lowering the operating
voltage to the coil.
The + side of the coil will have two feeds, this pink one (ballasted)
and one that comes from the starter solenoid which provides full battery
voltage to the coil during cranking.
If the pink wire is getting hot, that would indicate either an incorrect
coil which is drawing too much current, or perhaps the starter switched
feed to the coil may have fallen off the starter solenoid and is
grounding against the chassis or engine.
Hope this helps.
Kelvin.

Subject: White-Pink wire meltdown?
The 78 B seems to have a short I am having trouble running down. There
is a
white/pink stripe wire that has apparently gotten more than its' fair
share
of current as the insulation has separated enough to see bare wire. I
suspect it may have affected other wires as the white/greens to the coil
are
now cold.
This wire runs up toward the front and across the front of the radiator
along the right side. I haven't yet been able to trace where it is
headed. I
see nothing in Haynes about a pink striped white wire. Anybody out there
able to share some insights?
