2. See Figure 24. Pull the heat sink (16), with
multiplier (13) attached, out of the housing.
Continue pulling until you can grasp the
multiplier nut (12).
3. Unscrew the multiplier nut (12A) and disconnect
the electrode cable (12B) from the multiplier
(13).

6. Make sure the thermally conductive pad (24B)
and nylon shoulder washer (24A) are intact. If
not, install a new heat sink bracket kit, which
includes a new bracket (24C), pad, and washer.
Multiplier Installation
1. See Figure 25. Connect the harness plug (23)
to the multiplier (13).
2. Make sure the nylon shoulder washer (24A) is
correctly installed into the bracket (24C). Install
the multiplier on the bracket, tucking the
harness wiring into the slot in the bracket.
3. Secure the multiplier to the bracket with the
screw (26) and lockwasher (25).
4. See Figure 26. Inject approximately 0.3 cc of
dielectric grease into the multiplier well, so that
it is about 75% full.

5. See Figure 24. Insert the spring end of the
electrode cable (12B) into the multiplier well
until it bottoms out, then screw the multiplier nut
(12A) down tight.
