A LIGNING THE O PTICAL P ICKUP C ARD T AB
The optical pickup card is an electronic circuit board that accurately senses each drum
revolution. The pickup card is recessed into the side of your dyno. The optical
pickup card comes installed, the cable routed, and ready to use, but should be
checked for alignment before the drum is turned.
Should the pickup cable become disconnected, refer to Figure 2-5 for routing
instructions and page 2-9 for wiring instructions.
1
While looking through the optical pickup window, slowly turn the drum until the
tab approaches the pickup. The tab should pass through the pickup without
contact and should be centered in the pickup.
2 If the tab is not centered adjust by loosening the mounting screws.
The optical pickup is very delicate. Be careful not to damage the optical
pickup.
