Battery Test (Open Circuit Test)
Use a digital multimeter to measure the battery voltage.

Set the multimeter to the DC volts setting. The battery

and more accurate information (see Battery Service in
the Service and Repairs section).
Charging System Test
This is a simple test used to determine if a charging sys-
tem is functioning. It will tell you if the charging system
has an output, but not its capacity.
Start the engine and run at high idle (3200 RPM). Allow
the battery to charge for at least 3 minutes. Record the
battery voltage.
Use a digital multimeter set to DC volts. Connect the
positive (+) multimeter lead to the positive battery post
and the negative (--) multimeter lead to the negative bat-
tery post. Keep the test leads connected to the battery
posts and record the battery voltage.
After running the engine for at least 3 minutes, battery
voltageshouldbeatleast0.50volthigherthaninitialbat-
tery voltage.
An example of a charging system that is functioning:
NOTE: Upon starting the engine, the battery voltage
will drop and then should increase once the engine is
running.
At least 0.50 volt over initial battery voltage.

NOTE: Depending upon the condition of the battery
charge and battery temperature, the battery voltage will
increase at different rates as the battery charges.
Glow Plug System Test
This is a fast, simple test that can help to determine the
integrity and operation of your Reelmaster glow plug
system. The test should be run anytime hard starting
(cold engine) is encountered on a diesel engine
equipped with a glow plug system.
ammeter pickup around the main glow plug power sup-
ply wire and read the meter prior to activating the glow
plug system. Adjust the meter to read zero (if applica-
ble). Activate the glow plug system by turning the igni-
tion switch to RUN and record the multimeter results.
Use a digital multimeter and/or inductive Ammeter (AC/
DCCurrentTransducer).Properlyconnecttheammeter
to the digital multimeter (refer to manufacturers’ instruc-
tions) and set the multimeter to the correct scale. With
the ignition switch in the OFF position, place the
The Reelmaster glow plug system should have a read-
ing of approximately 9 Amps per glow plug (27 amps to-
tal on Reelmaster 5210 and 36 amps total on models
with four cylinder engine). If low current reading is ob-
served, one (or more) glow plugs is faulty.
