The rate of change is slow and the error gets larger as the revs build, such that winding the
car out gives about 2500 rpm. Needle rests at 0.
I cleaned all of the connections on the coil with the Dremel and gunked 'em with dialectric
grease. Seems normal now, but time will tell.
Thanks for the info.
