Neutral Engine Speed Control Coil; Fusible Link Harness - Toro Multi Pro 1200 Service Manual

Neutral Engine Speed Control Coil

The neutral engine speed control coil is energized by the
speed control switch and cruise module. The energized
coil becomes a magnet to hold the accelerator lever in
position and maintains engine speed for sprayer opera-
tion when the machine is stationary.
Testing
1. Park machine on a level surface, stop engine, en-
gage parking brake and remove key from ignition
switch.
2. Locate control coil next to accelerator lever under the
floorboard. Unplug coil connector from machine wire
harness (Fig. 21).
NOTE: Prior to taking small resistance readings with a
digital multimeter, short the meter test leads together.
The meter will display a small resistance value (usually
0.5 ohms or less). This resistance is due to the internal
resistance of the meter and test leads. Subtract this val-
ue from from the measured value of the component you
are testing.
3. Using a multimeter (ohms setting), verify control coil
resistance between the two terminals of the connector.
Resistance should be from 10.2 to 11.2 ohms.
4. If coil does not engage when voltage is applied or coil
resistance is incorrect, replace control coil.
5. Connect the coil connector to the machine harness
after testing.

Fusible Link Harness

The Multi Pro sprayer uses two (2) fusible links for circuit
protection. These fusible links are located in a harness
that connects the starter B+ terminal to the wire harness
(Fig. 22). If either of these links should fail, current to the
protected circuit will cease. Refer to wire harness draw-
ings in Chapter 10 -- Electrical Drawings for additional
fusible link information.
Testing
Make sure that ignition switch is OFF. Disconnect nega-
tive battery cable from battery terminal and then discon-
nect positive cable from battery (see Battery Service in
the Service and Repairs section of this chapter). Locate
and unplug fusible link connector from machine wire
harness. Use a multimeter to make sure that continuity
exists between the fusible link terminals. If either fusible
link is open, replace the fusible link harness.

After fusible link testing is complete, make sure that fus-
ible link harness is securely attached to starter B+ termi-
nal and wire harness. Connect positive battery cable to
battery terminal first and then connect negative cable to
battery.
