<VV> Tach lead?

[Frank DuVal]

9.8 ohms is way too low for the points to work. It is like the points 
never open from the coil's perspective.

I suspect the tachometer is defective. Measure the resistance from the 
tach terminal to ground (case of the trach) with the tach wire 
disconnected from the tach.

Gets a 9.8 Ohm reading  for just the wire to ground. Anyone know what the correct reading should be. 9.8 Ohms seems a lot low to me.
