If your car is fitted with an alternator the warning light should not come on when the engine is idling, provided the idle setting is correct, because an alternator produces current even at low speeds.
Is the ignition switch in the off position?
With the ignition switch in the off position, you should not read any voltage on the multi-meter. The next step will be to turn the key to the accessory position. Be sure not to turn the key too far at this point. If you have selected the proper source, you will now read a positive voltage source (around 12v).
How do you find the ignition ( on ) source in a car?
To find the ignition (on) source, start by ensuring that the ignition switch is in the “off” position. Insert the positive probe in any connection (except the constant 12v source). With the ignition switch in the off position, you should not read any voltage on the multi-meter. The next step will be to turn the key to the ignition (on) position.
How to test the voltage of the ignition switch?
Method 1: Using a Test Light 1 Turn the ignition switch off and disconnect the module’s wire. 2 Find the starter solenoid’s S terminal and disengage it. 3 Rotate the ignition key and place it on the run status. 4 Probe your ignition red wire connection to test the voltage. 5 Test the ignition coil’s battery in the same way.
How can I tell if my ignition switch is bad?
Put the multimeter negative lead into the good ground of the distributor base. Turn the key and set it to the run position. Measure the voltage by using the meter. If the voltage is even slightly lower than 90%, then your ignition switch has problems.
When do you need to replace the ignition switch?
It may result in some electrical components stop working, the car does not start or dies immediately after being started. You may need to replace the switch if the problem becomes severe or the car does not respond at all. But, you have to know how to test ignition switch to determine that it actually is broken and needed to be fixed.

How To Test Ignition Switch With A Test Light Step 1: Disconnect the module’s wire connector after turning the ignition switch off. Step 2: Rotate the ignition key and place it to the run position.
What should I do if I need to replace my ignition switch?
Reconnect the cable to the negative (-) terminal on the battery, then insert the key into the ignition and turn it to start the vehicle. The vehicle should start without any issue. If it doesn’t, remove the ignition switch and reinstall it. Shut the engine off (if it starts) and disconnect the battery again.
How do you remove a battery from an ignition switch?
Use an appropriate sized wrench to loosen the nut holding the cable on the negative (-) terminal and then slide it off the post. You don’t need to remove the positive cable from its terminal. Tuck the negative cable to the side of the battery to make sure it doesn’t accidentally come into contact with the terminals.
Where do I find the ignition switch on my car?
Locate the battery in the engine bay or trunk of your vehicle. It will look like a black box with a positive (+) and negative (-) post sticking out of the top of it. Use an appropriate sized wrench to loosen the nut holding the cable on the negative (-) terminal and then slide it off the post.
