Starting System Problems?

BROADVIEW, IL- September 15, 2014 – Before attempting any diagnosis of a vehicle’s starting system, be sure that the battery is properly charged and that all the connections are clean, free of corrosion and tight.

If the engine starts poorly or not at all, check the engine compression, ignition and fuel system.

If the engine cranks slowly or not at all, perform the following checks while cranking to diagnose a possible fault.

  1. Check the voltage at the battery terminal of the solenoid switch. It should be at least 9.6V or to the manufacturer’s specification. If it is not, check for a voltage drop between the battery and the starter solenoid battery terminal. Clean the battery posts or replace the battery cables. Entire cables should be replaced versus repairing the battery cable ends.
  2. Check the voltage at the starter terminal. It should also have a minimum of 9.6V (while cranking). If it does not, remove and clean the cable connections. If cleaning does not cure the problem, the starter solenoid is defective and should be replaced
  3. Perform a “Voltage Drop Test” using a digital volt meter. Place the positive probe on the starter case and the negative probe on the negative battery post. If the reading exceeds .1 volt, clean or replace the battery-to-engine cable or connection.
