Electrical System Quick Checks

Battery Test (Open Circuit Test)

Use a multimeter to measure the voltage between the
battery terminals.
Set the multimeter to the DC volts setting. The battery
should be at a temperature of 60
C). The ignition key should be in the OFF position and
all accessories turned off. Connect the positive (+) me-
ter lead to the positive battery post and the negative (–)
meter lead to the negative battery post.
NOTE: This test provides a relative condition of the bat -
tery. Load testing of the battery will provide additional
and more accurate information.

Charging System Test

This is a simple test used to determine if a charging sys-
tem is functioning. It will tell you if a charging system has
an output, but not its capacity.
Use a multimeter set to the DC volts setting. Connect the
positive (+) meter lead to the positive battery post and
the negative (–) meter lead to the negative battery post.
Leave the test leads connected and record the battery
voltage.
NOTE: Upon starting the engine, the battery voltage
will drop and then should increase once the engine is
running.
NOTE: Depending upon the condition of the battery
charge and battery temperature, the charging system
voltage will increase at different rates as the battery
charges.

Neutral Switch Operation

CAUTION
Do not disconnect neutral interlock switch. It is
for the operator's protection. Check operation of
the switch daily to make sure the interlock sys-
tem is operating correctly. If the neutral switch is
not operating properly, replace it before operat -
ing the machine. To ensure maximum safety, re-
place switch after every two years or 1500 hours,
whichever comes first..

Start the engine and run at high idle (3050 – 3150 RPM).
Allow the battery to charge for at least 3 minutes. Record
the battery voltage.
Test results should be (example):
At least 0.50 volt over initial battery voltage.
