The engine management earth cables are gathered at a insulated binding post at the front of the ECM
mounting panel, with an earth cable connecting this post to the chassis earth point. This arrangement is used
to reduce the risk of earth paths being created through the ECM casing.
MN.7 - WIPER MECHANISM
The windscreen wiper mechanism comprises a uni-directional motor with an external rotary link, a con-
necting rod, and a pair of actuating links which join the connecting rod to the arms of the wiper spindle. This
mechanism provides the wiper with a motion which is slowed at each end of its travel in order to ease the inertia
loads during direction changes, to the benefit of refinement and durability. The motor and wheelbox are
mounted on a single fabricated steel bracket which is bolted to the windscreen scuttle panel.
To remove the wiper mechanism:
1. Release the front bonnet latch mechanism from the plinth integral with the motor/wheelbox mounting
bracket, and disconnect the washer tubing.
2. Remove the wiper motor protective cover by releasing the two screws into the windscreen buttress, and
the patch of adhesive between the inboard end and the screen gutter. Disconnect the harness plug from
the motor.
3. Remove the wiper arm from the spindle, and the spindle rubber surround.
4. Release the three screws securing the motor mounting bracket to the windscreen frame - one at each
side of the spindle, one at the motor end, and withdraw the complete mechanism from the car.
5. If the motor is separated from the mechanism, the position of the rotary link should be marked against the
motor shaft for reference when re-fitting. The motor should be in the 'park' position before fitting, and the
mechanism at full travel so that the rotary link and connecting rod are aligned in the fully extended
position.
