This would suggest some manner of bad wiring either to the coil itself, or from the battery to ground.

If you're seeing less than 6 volts there or inconsistent voltage, I would check that you have 6 volts in the following places with the positive lead of the meter connected to a good ground (such as the head bolts):
  • negative lead to starter switch terminal (where battery cable runs)
  • negative lead to safety fuse wire coming from starter terminal
  • negative lead to safety fuse wire leading to terminal block
  • negative lead to passenger terminal post
  • negative lead to drivers terminal post
  • negative lead to coil negative terminal

Somewhere along that path you should find that voltage drops or is lost. If it is missing at all of them, perhaps you have a faulty ground, so you could try moving the positive lead somewhere else and re-checking to confirm.
