Check battery negative (ground) cable and
connections. Connect a voltmeter from the
negative battery terminal to the bolt that mounts
the battery negative cable to the ground
connection on the engine or frame. While
cranking the engine, a voltmeter reading higher
than 0.4 volts indicates excessive resistance.
Check the cable for loose connections or the
battery terminal for corrosion. Clean and tighten
the terminal post and cable ends.
d) To check negative post battery terminal connection,
refer to positive post test above.
Check key switch, starter relay, and solenoid
circuit. Connect a voltmeter across the "Battery"
terminal of the solenoid and the "Switch" terminal
of the solenoid. A voltmeter reading of 1.02.0
volts is expected with the engine cranking. A
reading of more than 2 volts indicates excessive
resistance. Check the wiring, connections, and
switches in this portion of the circuit.
terminal. With the engine cranking, a voltage
reading of less than 0.2 volts should be
measured. A reading higher than 0.2 volts
solenoid. Check the solenoid contact disc and
