Disable the ignition so the engine doesn’t start; crank the engine for 2-3
seconds.
A voltage drop in excess of 0.5 V indicates defective ground.
Clean and inspect the battery cable connections and the ground, and test again.
(3) Battery Power to Starter Solenoid (+)
This test checks battery source efficiency to the starter solenoid.
.Set the rotary switch to Voltage.
.Establish the base voltage that you will compare test voltage against (see base
voltage, Volt Drop Test [1]).
.Connect the positive (+) lead to the positive (+) battery terminal.
.Connect the negative (-) lead to the positive (+) terminal on the starter
solenoid.
.Set the Min/Max feature on the meter.
.Disable the ignition so the engine doesn't start; crank the engine for 2-3
seconds.
A voltage drop of more than 0.3 volts would indicate a poor ground circuit.
Clean and inspect the battery cables and cable connections; test again.
(4) Battery Power to Complete Starter Circuit (+)
This test checks battery power efficiency to the starter through the starter
solenoid.
.Set the rotary switch to Voltage.
.Establish the base voltage that you will compare test voltage against (see base
voltage, Volt Drop Test [1]).
.Connect the positive (+) lead to the positive (+) battery terminal.
.Connect the negative (-) lead to the positive (+) terminal on the starter motor.
.Set the Min/Max on the meter.
