Electrical; Electric Start System; Lighting; Ignition Switch - Toro Power Max Service Manual

Power Max models have 3 very simple electrical
systems. Each is separate from the other so a problem
in one area will not affect the others.

ELECTRIC START SYSTEM

All models have an electric start system standard. All
4 cycle engines use the Tecumseh electric start system.
See the Tecumseh service manual for repair information.
The 2 cycle models have a Toro system. The 2 Cycle
electric start is covered in the E Engine Service Manual
Form # 492-0647.

LIGHTING

Some 4 cycle models have a light standard or light kit
available. There is no light kit for 2 cycle models.
The lighting system consists of an alternator coil, a wire
leading to the light fi xture and the fi xture itself. This
light operates whenever the engine is running. The
alternator is a Tecumseh part; replacement parts and
troubleshooting assistance are obtained through the
Tecumseh system.
The light fi xture and the wire harness are Toro parts. The
light bulb is replaceable.

IGNITION SWITCH

All models have an on/off switch.
On the 4 cycle models the switch is an engine part and
is built into the carburetor heater box, next to the throttle.
Use Tecumseh service information for troubleshooting
and repair.
The 2 cycle models have a simple on/off switch mounted
in the rear engine cover. When the key is turned off, the
switch closes, the magneto primary is grounded to the
engine block and the engine stops. When turned to on,
the ground is disconnected allowing the ignition to fi re.

ELECTRICAL

The wires run from the ignition coil, under the blower
housing, over the foam pad to the ignition switch. The
other wire runs from the switch to the cylinder head bolt.
Make sure to secure the wires to the primer line with a
wire tie (Fig. 229).
To test the switch remove the wires and attach a
continuity light or ohmmeter. When the switch is on there
should be no continuity. When the switch is off there
should be continuity between the terminals (Fig. 230).
See the engine section for access to the ignition switch
on 2 cycle models.
