Starter Motor: Description and Operation
Starter Motor
The starter motor has permanent magnets to
reduce strain on the battery.
A planetary gear increases the starting torque.
The starter motor circuit consists of tow sub-circuits:
-
working circuit
-
operating circuit
Working circuit
The working circuit goes from the battery's positive terminal to terminal 30 on the starter motor.
Operating circuit
The operating circuit goes from the battery's positive terminal to the ignition switch and on to the starting relay, and via the starting relay to terminal 50
on the starter motor, which is the operating current connection on the solenoid.
The starting relay actuating coil is grounded via the TWICE control module when it has received the ready signal from the immobilizer unit.
WARNING: Nothing may be connected to the circuit between the generator and the battery. Spikes of up to 100 V can occur.
