(2) Trace the wires from the charge electrode to their connections at the

conduit wiring in the upper part of the head (see pg. 8--5).

(3) Cut the heatshrink sleeving around the connections and disconnect

the electrode wires.

CAUTION

During the following steps, do not touch the charge
electrode mounting plate screws at the rear of the
