IGNITION SWITCH TESTING (ELECTRIC
START MODELS)
Refer to the appropriate model and year wiring diagram for
ignition switch wire colors and connections.
1. Disconnect wires. Set the multitester dial to the ohms
Ω
position.
2. With the key in the off position, check the resistance
between the G (Ground, brown) terminal and the M (Mag,
black) terminal. This reading must be less than.4 ohms.
3. Turn the key to the on position. The multitester should
now read an open circuit (OL).
4. Move the tester lead from the G terminal to the switch
housing and re-check the reading. It should also be an
open circuit (OL).
5. Place one of the tester leads on the B (Battery, red)
terminal and the other tester lead on the S (Starter, blue)
terminal. With the key in the on position, there must be an
open circuit (OL) reading.
6. Turn the key to the start position. The reading should be
less than.4 ohms. Readings other than the ones listed
indicate a defective switch.
500/600 TEMPERATURE LIGHT
Models with TPS are fitted with a thermistor sensor. This
sensor outputs a variable resistance with temperature. This
allows more capability for control when the over heat
indicator light illuminates. Higher throttle positions require
lower temperature for the light to come on, possibly leading
the operator to believe it to be a blinking light.
For example, the TEMP light will come on at idle (under 2000
RPM, 0% throttle) if coolant temperature reaches 230
_ F
(110 _ C). Timing retard initiates at 176 _ F if the TPS input is
over 80-100%. For more severe conditions, the engine fail-
safe is turned on at high TPS input and high temperatures.
At room temperature 68 _ F (20 _ C) the thermistor should read
2189 to 2675 ohms. See chart below for other temperature
resistances.
SPEED CONTROL ASSURANCE SWITCH
The speed control assurance consists of two series connected
switches. If one or both switch plungers are positioned
inward, the circuit is open and the engine will run. At idle,
with the throttle lever properly adjusted, the bottom switch
circuit is open and the plunger is inward. The top switch
circuit is closed, and the plunger is outward. The speed control
circuit is open, allowing the engine to run. As the throttle lever
is actuated to an off idle position, the top switch circuit is
opened (plunger in) and the bottom switch circuit is closed
(plunger out). The speed control circuit is still open, allowing
the engine to run. In the event the carburetor or controls
malfunction and allow the throttle cable to become slack, the
circuit will close (both switch plungers out), grounding the
ignition system and causing the engine to stop.

This clearance is controlled by the throttle cable sleeve(s) and
