Heavy cables, connectors and switches are utilized by the starting system because of the large amount of
amperage this system is required to handle while cranking the engine. For premium starter motor function, the
resistance in the starting system must be kept to an absolute minimum.
A discharged or faulty battery, loose or corroded connections, or partially broken cables will result in
slower−than−normal cranking speeds. The amount of damage evident may even prevent the starter motor
from rotating the engine at all.
Vehicles equipped with a manual transmission are equipped with a Clutch Pedal Position (CPP) switch in the
starter circuit, which is designed to prevent the starter motor from operating unless the clutch pedal is
depressed. Vehicles equipped with automatic transmissions are equipped with either a Park/Neutral Position
(PNP) switch, a Manual Lever Position (MLP) switch or a Transmission Range (TR) sensor in the starter
circuit. These switches prevent the starter motor from functioning unless the transmission range selector lever
is in Neutral (N) or Park (P).
