The
Model T Engine
Coil Boxes
The
upper contact cushion spring should have approximately .005
clearance at A to the upper bridge D. This clearance should
extend the full length of the cushion spring. Push the vibrator
spring down to core and adjust nut C until the upper point just
makes contact with a .029-.031 feeler gage. Lock C position with
upper nut. Adjust tension on the vibrator spring by lightly
tapping the back of the vibrator spring bridge (or by prying it
up) until the coil draws 1.3 amperes at 6 volts input. When all
4 coils are properly adjusted, they should all have a uniform
pitch like the sound of an angry bee, about 275 cps. |
