Connect the Flat cable end from the Cylinder Ass’y to the
VP-1 PWB Ass’y using the Relay jig to provide simple
repairing and adjustment of the VP-1 PWB Ass’y, as shown in
Fig.2.2.7. Further, when adjusting theVP-l PWBAss’y, be sure
to make contact an end of Shield case with Bracket of the
VP-1 PWB Ass’y to maintain the shield effect. If the VP-1
PWB Ass’y does not contact, there is insufficient ground and
