Troubleshooting Information
Checking S3 seat contact switch
Note:
Actuating the starter without a load on the
seat will crank the engine but not start it!
–
Disconnect wire connections from seat con-
tact switch.
–
Connect an ohmmeter to check seat contact
switch for continuity.
–
With a physical load on the seat cushion, the
switch opens, and there is no continuity.
–
In the absence of a physical load on the seat
cushion, switch contacts are closed.
–
Adjust or replace seat contact switch as re-
quired.
Checking spark plug (gasoline & LPG engine)
Checking seat contact switch S3
Check spark plug
(gasoline and LPG engine)
–
If ceramic insulator shows signs of break-
age of cracking, spark plug must be replaced.
–
Heavily fouled spark plugs must be replaced.
–
Using a feeler gauge, measure electrode gap,
and bend electrodes to adjust as required.
–
To compress captive seal washer on new
spark plug, screw in plug hand-tight, then
tighten 1/2 turn. Tighten used spark plugs
only by 1/8 to 1/4 turn.
Check oil level switch S9
(gasoline and LPG engine)
In the event that the engine oil level drops down
too far, the oil level switch cuts out the ignition.
This causes the engine to stall and will prevent
engine restarts.
–
Remove the terminal of the yellow wire.
–
Using the ohmmeter, check the connecting
terminal for continuity.
–
If the oil level is sufficiently high, there will be
no continuity.
–
If the oil level is too low, there must be con-
tinuity.
–
Top up engine oil or replace oil level switch
as required.
