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 to 100 F. The ignition
key should be off and all accessories turned off. Connect
the positive (+) meter lead to the positive battery post
and the negative (–) meter lead the 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.
Glow Plug System Test (GR3200–D)
This is a fast, simple test that can help you determine a
glow plug system's integrity and operation. The test
should be run anytime hard starting (cold) is encoun-
tered on a diesel engine equipped with a glow plug sys-
tem.
Tool(s) required: Digital multimeter and/or AC/DC
current transducer (Hall Effect).
Test instructions: Properly connect the current transduc-
er to the digital multimeter (refer to manufacturer's

Starting System Test

This is an excellent test to use when a "slow crank/no
start" problem is encountered. It will tell you if the prob-
lem is due to an electrical open, short or high resistance
in the starter circuit.
Note: The Battery condition and state of charge must
checked before testing the starter system.
Tool(s) required: Digital multimeter and/or AC/DC
current transducer (Hall Effect).
Test instructions: Properly connect current transducer to
the digital multimeter (refer to manufacturers instruc-
tions). Set the multimeter on volts scale. With the key off,

instructions). Set the multimeter on the volts scale. With
the key off, place the current transducer around the main
glow plug power supply wire(s) and read the meter prior
to activating glow plug system. Adjust the transducer to
read zero (if applicable). Cycle the glow plug system at
least two times (per instructions in Operator's Manual)
and record the final results.
The Reelmaster 3200–D glow plug system should have
a reading of about 21 Amps.
place the current transducer around the main negative
(–) battery cable and read the meter prior to activating
the starter system. Adjust the transducer to read zero (if
applicable). Crank the engine for at least 3 seconds and
record the results. Typical starter system draw is as fol-
low:
170 to 220 Amps at 65 F for the GR3200–D.
95 to 150 Amps at 65 F for the GR3200.
If current draw is significantly higher than listed, check
for a shorted condition. If current draw is significantly
lower than listed, check for high resistance.
