STARTER CURRENT DRAW TEST
IMPORTANT
: When making the starter current draw
test make sure that all parasitic load is removed from the
engine and that engine has the correct viscosity oil.
Engine temperature should be at least 70°F (21°C).
Make sure battery and solenoid connections are clean
and tight.
NOTE
: Battery voltage must not be below 11.7
volts.
Test Equipment
The following equipment is required to test current draw
of starter, Fig. 9.

Testing Starter
NOTE
: To prevent engine from starting, remove
spark plug wires from spark plugs and ground
ignition using two Ignition Testers, Tool
Leave spark plugs installed.
The starter current draw test will be performed with the
meter in the
position.
300mV
The DC Shunt must be installed on the negative (-)
terminal
of the battery, Fig. 10.

1. Attach
meter test lead to
RED
terminal on shunt.
2. Attach
meter test lead
BLACK
terminal on shunt.
3. Activate starter.
a. Allow 3 seconds for meter reading to stabilize.
4. Current draw should not exceed 80 amps DC.
If amperage draw exceeds specification, remove starter
from engine and perform No Load starter current draw
test.
