Cover Removal and Replacement
1. Remove the two 12-point terminal connectors by
inserting a flat-head screwdriver between the
terminal connector and the ASTAT-IBP cover, as
illustrated in Figure 1.
Do not remove the wiring from the terminal
connectors.
Carefully release the terminal connector from the
pins. Carefully pull the terminal connectors, with
the wiring, straight off the ASTAT-IBP starter.
2. Remove the plastic cover by pressing and releasing
the plastic tab on each side of the cover with a flathead screwdriver, as illustrated in Figure 2.

boards. Carefully push down on the cover until the
two tabs snap into place. It may be necessary to push
in slightly on the outside of the lower plastic
housing.
4. Replace the terminal connectors through the plastic
cover onto the connector strips. Ensure that the
terminal connectors snap into place.
