calibrating tachs doesnt have anything to do with the accuracy of the tach signal coming from the alternators, or the accuracy of glendenning synchros.

tachs convert the tach signal coming from the alternator into an averaged current for the tach's meter. ALL meters vary in their sensitivity to current. Thats why its dang near impossible to find 2 that display the same rpms.
