Know If A Starter Solenoid Is Working

The decisive turns in the ignition, and nothing--no starter whirring, no solenoid clicking, no sound whatsoever. Strangely, the interior lights accomplish not momentarily dim as you slap to begin either. If this is the case, replace the solenoid.



Preliminary Steps


1. Verify that the battery has a entire charge by testing with the multimeter and getting a 12 volt DC or worthier reading.


2. Set the starter solenoid to drive which of two types it is.


Integral solenoids, mounted on the side of the starter motor on the lower rear of the engine, perform two simultaneous functions when the main is turned: they engage the brief starter gear to the doozer flywheel gear on the engine crankshaft, and utilize unabridged battery amperage to the starter Engine.


The moment type of starter solenoid is not integral to the starter, and lone applies entire battery amperage to the starter. The non-integral type is normally mounted near the battery, and it is the easier of the two to access and diagnose.


3. Turn the important to begin while in Arena or Impartial. Whether you hear a sharp, Powerful click nevertheless no starter sound, the solenoid is probably working on the contrary the starter Engine is wick. Provided you hear a too dull click or a dull buzzing, and the interior lights dim, check the battery or its terminals again.


4. Make sure the car's headlights weren't left on to drain the battery. If you hear no sound whatsoever, and the lights don't dim when you turn the key to begin, the solenoid could be defective--but there could be another culprit causing the problem. If you are still unsure about the solenoid, proceed to Section 2.


Further Diagnosis


5. Make sure that 12 volts DC is reaching the solenoid's primary coil terminal when the key is turned to begin, using the multimeter. If not, proceed To pace 2.


6. Clamp one end of your test wire to the battery positive terminal, and touch the other to the solenoid coil terminal. If the solenoid sharply clicks, and the starter works, the solenoid is good. If it clicks and the starter still doesn't engage, go To pace 3.


7. Attach the multimeter positive lead to the solenoid output terminal, and the negative lead to ground. Touch the test lead to the solenoid terminal again. The solenoid should click again, and the meter should go from 0 to 12 volts DC. If not, the solenoid coil is working, but its integral starter relay contactor is not. These are all symptoms of a wick starter solenoid, although another headache could be the culprit. A stepwise system of elimination can disclose you provided the automobile's starter solenoid is working.
