ELECTRICS
ELECTRIC STARTER MOTOR
On engines equipped with electric starter motor and directly coupled to an application (direct drive, belt drive,
chain drive, etc...), the load on the starter motor should be checked.
If the starter motor current is too high, a provision should be made for unloading the engine when starting.
For example : centrifugal clutch, belt tensioner.
On compressor applications, a manual or automatic pressure release valve should be provided on the
compressor to lower the load on the electric starter motor or recoil starter.
Measuring method:
With the engine in cold condition, note the oil viscosity and oil temperature.
Put the ignition switch to off.
Use a clamp-on ammeter on the cable between battery and starter motor and measure:
the starter motor peak current
-
- the starter motor cranking current
ELECTRIC CONDUCTOR SECTION
The electrical resistance of a wire increases in proportion to length, decreases with the increase of
diameter and varies according to material of the conductor.
Consult the reference table below for conductor cross-section selection.
