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
o
to 100
o
F(16
o
to 38
o
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 ofthe bat-
tery. Load testing of the battery will provide additional
and more accurate information.
Voltage Measured
Battery Charge Level
12.68 v (or higher) Fully charged (100%)
12.45 v 75% charged
12.24 v 50% charged
12.06 v 25% charged
11.89 v 0% charged
Charging System Test
This is a simple test used to determine if a charging sys-
tem is functioning. It will tell you if acharging system has
an output, but not its capacity.
Use a multimeter set tothe 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.
Start the engine and runat highidle (3050 -- 3150RPM).
Allow the battery to chargefor at least 3 minutes.Record
the battery voltage.
Test results should be (example):
At least 0.50 volt over initial battery voltage.
Initial Battery Voltage = 12.30 v
Battery Voltage after 3 Minute Charge = 12.80 v
Difference = +0.50 v
Neutral Switch Operation
CAUTION
Do not disconnect neutral interlock switch. It is
for the operator’s protection. Check the opera-
tion of the switch daily for proper operation. Re-
place malfunctioning neutral interlock switch
before operating the machine.
Neutral switch operation is described in the Multi Pro
5700--D Operator’s Manual. Testing of the neutral
switch is included in the Component Testing section of
this Chapter.
