Extension jumper leadStep 1:measurmentConnect the DVOM between the battery positive post andthe main positive connection to the starter motor.Measure the voltage drop during cranking on thevoltage side of the starter circuit.BatterySolenoidStarterFigure 1: Checkingthe positivesideof StarterMotorCircuit

" -,Step 2:measurementConnect the DVOMbetween the battery negative postand a clean spot on the starter motor housing. Take a. measurement during cranking. This tests the voltagedrop on the negative side of the circuit.-NegativePostSolenoidFigure 2: Check at a clean spoton the starter housingStep 3:measurementConnect the DVOMleads as shown. Test the connectionbetween battery positive post and the battery positivecable terminal end while cranking.PositivePostFigure 3: Checking voltage drop betweenthe positive battery post and the

".Step 4:measurementNext test the positive battery cable for voltage drop.Connect the DVOM as shown to take a reading acrossthe positive battery cable.SolenoidStarierFigure 4: Checking the positive batterycable resistance using a voltagedrop test.Step 5:measurementNow check the connection between the battery positive.cable and the solenoid while cranking the engine. Youare measuring the terminal end and connection.SolenoidFigure 5: Checking he voltage drop betweenthe positive battery cable lug and thesolenoid stud.

~-, -Step 6:measurementClean and suspect terminals and replace any faultycomponents. Then, re-check the system by completingSteps 1 & 2 again.REMEMBER:All tests are made with the engine cranking.The rule of thumb is that each termination in the circuit should have avoltage drop of no greater that 0.2 volts.
