Repair and Diagnosis: Electrical: Starter: Description

T100 uses a Nippondenso 4-brush, solenoid-actuated, gear reduction-type starter, equipped with over-running clutches. The brush holder assembly retains 4 brushes and springs in the starter housing.

Reduction gear type starters contain an integral solenoid attached to drive housing, a reduction idler gear and bearing installed into starter housing, and a clutch drive assembly. The clutch drive assembly is mounted to starter housing and is driven by the reduction idler gear from armature shaft. The brush holder assembly retains 4 brushes and 4 springs in the end cover of field frame housing.

A starter relay is used to energize starter. Manual transmission vehicles use a clutch start switch and automatic transmission vehicles use a park/neutral switch to energize starter relay. On models with theft deterrent system, theft deterrent system ECU provides ground for starter relay.

A clutch start cancel switch is optional. When this switch is turned on, it will allow engine to be started without depressing clutch pedal when transmission is in Neutral.
