While working on another issue I came across a situation I can not believe possible.  Car is a 62 with an alternator conversion complete with Late regulator.  In my troubleshooting for the other problem I had two volt meters clipped into the system .  One across the battery terminals and one from ground to the positive terminal of the coil.  This of course was reading through the resistance wire which would normally be showing around 9 volts in the RUN condition.  The battery meter was showing a rock solid 14.2 volts.  The one at the coil though was flashing all over the place showing voltages as high as 19 volts and as low as 8 or 9 volts.  I find it hard to believe that this is normal.  So what gives here?
