ELECTRICAL AND IGNITION
ELECTRIC START TESTS
After re-installing the solenoid, coat all wires and
terminals with
Black Neoprene Dip
.
No Load Current Draw Test
Securely fasten starter in a vise or suitable fixture
before proceeding with this check.
Use a battery rated at 500 CCA (60 amp-hr) or
higher that is in good condition and fully charged.
IMPORTANT:
The driven gear and pinion
assembly must be removed for this test.
Use an inductive ammeter or connect a 0 to 100
amp ammeter in series with a heavy jumper
between the battery positive (+) terminal and the
starter positive (+) terminal.
Fluke
model 334 or 336,
Snap-On
model MT110
or EETA501, and various other ammeters should
be available through local tool suppliers.
Attach or hold a vibration tachometer, such as a
Frahm
†
Reed
tachometer, to the starter.
Complete the circuit with a heavy jumper between
the battery negative (–) terminal and the starter
frame.
Monitor the starter RPM and current draw.
•
At 10,500 RPM the ammeter should show a
maximum of 30 A.
