If, in any of the above tests, the correct lamps do not light or
additional lamps are lighted, replace the lower harness.
Test to detect improper plate adjustment. If, after a new lower
harness assembly has been installed, either lamp (Y or YB)
remains on when transmission is in neutral, in test (E) above, the
contact plate is incorrectly adjusted. To adjust contact plate,
loosen the four screws holding contact plate assembly, then see
if plate is free to move back and forth through movement
permitted by elongated holes. If not, remove plate from trans-
mission cover and care-fully cut off or remove locating dowel pins. Replace contact plate as nearly as possible in its original
position and partially tighten the four screws so that plate may
be moved to its proper position.
If test lamp (YB) remains lighted when transmission is in
neutral, move plate very slightly to the rear until lamp (YB) goes
out. If lamp (Y) remains lighted, move block forward.
The proper setting is obtained when the movement of
shift lever forward from neutral necessary to bring lamp (YB)
on is equal to the backward movement required to bring lamp
(Y) on.

Failures Resulting from Faulty Circuits
See Wiring diagram, Figure 1102. A faulty selector switch may cause any of the failures listed below. A master selector
switch should be used when checking the control. If control operates perfectly with master selector switch, an investigation of
the other units is unnecessary.
