Check for continuity between the following terminals, if meter shows
continuity, replace main key switch.
Terminal
4 6
and
8. With main key switch set to the START position, PUSH IN the key,
check for continuity between terminals (2), (8), (10) and (12). lf meter
does not show continuity, between all four terminals replace main key
switch. Check for continuity between aIl terminals (4) and (6), if meter
shows continuity, replace main key switch.
Neutral Start Switch Test
1. For models without remote control box: Disconnect terminals
32
(2) and (3).
For models with remote control box: Disconnect terminals
33
(2), (3) and (4).
2. For models without remote control box: Set analog multimeter
for continuity. With shift lever set at NEUTRAL FORWARD, and
REVERSE positions, check for continuity between a clean chassis
ground and one of these terminals (test one terminal at a time):
2
Terminal
If meter shows continuity in any of these tests, replace
32
neutral start switch (1).
For models with remote control box: Set analog multimeter
33
fol continuity. With remote control lever set at NEUTRAL,
FORWARD, and REVERSE positions, check for continuity between
a clean chassis ground and one of these terminals (test one terminal
at a time):
2
Terminal
lf meter shows continuity in any of these tests, replace neutral start
switch.
3. With shift lever set at NEUTRAL check for continuity
32 33
between terminals (2) and (3).
If meter does not show continuity, put shift lever in
34 35
FORWARD gear and press in neutral start switch
plunger (1) aIl the way in. lf meter shows continuity, adjust, repair,
or replace shift lever linkage. lf meter does not show continuity,
replace the neutral start switch.
4. For models with remote control box ONLY: With remote
33
control lever set at FORWARD and then REVERSE, check for
continuity between terminals (3) and (4). lf meter does not show
