Starter: |
|
|
| Battery
power is supplied to the starter through a heavy cable that can
handle the amperage draw during start. |
| The
cable connects the positive side of the battery, to the starter solenoid.
There are two other terminals on the solenoid. "R" supplies
power to the ignition coil; "S" receives power from the
ignition switch. When the ignition switch is moved to the start position,
the low amperage closes the starter solenoid. This closure grounds
the circuit through the starter, to the engine block, back through
the negative battery cable, to the battery. |
| This
grounding engages the bendix, which pushes the starter gear out,
to engage the flywheel. As current flows through the starter windings,
the starter spins. When the ignition switch is released from start
to run, the ground is opened releasing the solenoid, stopping current
flow from the battery. Springs return the bendix, which disengages
the gear from the flywheel. With the ignition switch is in the run
position, R is supplying power to the coil. |
