Starter Motor; Starter Relay - Toro 500 EFI Service Manual

RESISTANCE (AC Generator)
CAUTION
Always disconnect the battery when performing resis-
tance tests to avoid damaging the multimeter.
1. Set the meter selector to OHMS position.
2. Test between the three yellow wires for a total of
three tests.
3. The meter reading must be within specification.

Starter Motor


NOTE: The starter motor is not a serviceable com-
ponent. If the starter is defective, it must be replaced.
REMOVING
1. Disconnect the battery.
CAUTION
Always disconnect the negative battery cable from the
battery first; then disconnect the positive cable.
2. Remove the nut securing the positive cable to the starter;
then remove the cable from the starter.
3. Remove the two cap screws securing the starter with
ground wires to the crankcase; then remove the starter.
Account for the wiring forms and an O-ring.
INSTALLING
1. Apply a small amount of grease to the O-ring seal on the
starter; then install the starter into the crankcase. Secure
with two machine screws and wiring forms.
2. Secure the positive cable to the starter with the nut.
3. Connect the battery.
TESTING VOLTAGE
Perform this test on the starter positive terminal. To access
the terminal, slide the boot away.

NOTE: The ignition switch must be in the ON posi-
tion, and the shift lever in the NEUTRAL position.
1. Set the meter selector to the DC Voltage position.
2. Connect the red tester lead to the starter terminal; then
connect the black tester lead to ground.
3. With the starter button depressed, the meter must show
battery voltage and the starter should operate.


NOTE: If the meter showed battery voltage but the
starter did not operate or operated slowly, inspect
battery voltage (at the battery), starter condition, and/
or ground connections.

NOTE: If the meter showed no battery voltage,
inspect the main fuse, ground connections, starter
lead, battery voltage (at the battery), starter relay, or
the neutral start relay.

Starter Relay

1. Remove the seat base and battery cover; then using
the multimeter set to the DC Voltage position, check
the relay as follows.
2. Connect the red tester lead to the positive battery ter-
minal; then connect the black tester lead to the starter
cable connection on the starter relay. The meter must
show battery voltage.

NOTE: Make sure the ignition switch is in the ON
position, transmission in neutral, and parking brake
set.
3. Depress the starter button while observing the multi-
meter. The multimeter should drop to 0 volts and a
"click" should be heard from the relay.

NOTE: If a "click" is heard and more than one volt is
indicated by the multimeter, replace the starter relay.
If no "click" is heard and the multimeter continues to
indicate battery voltage, proceed to step 4.
