Replaced Alternator Car Still Dies

Last Updated on April 5, 2023 by Ryan

If an alternator has been replaced and the car still dies, there are a few possible causes. It’s important to diagnose the issue accurately in order to address it properly. One potential cause could be a faulty connection between the battery and the alternator.

This could be due to poor wiring or corrosion on either of those components. Another possibility is that the new alternator isn’t providing enough power for all of the car’s electrical systems, which can cause issues with starting and running as well as other problems such as lights dimming while driving or stalling when turning on accessories such as air conditioning or heating. In some cases, a defective voltage regulator may also be responsible for this problem, so it should not be overlooked during diagnosis.

Finally, if all else fails check for any loose belts that may prevent proper charging of your battery by your newly installed alternator.

If your car is still dying even after you’ve replaced the alternator, it could be a sign of a few different issues. It’s best to take your vehicle into the shop for an inspection and diagnostic testing so that any underlying problems can be identified and fixed before they lead to bigger, more costly repairs.

Some of the most common reasons why a car may not start even with a new battery and alternator include issues such as corroded or loose connections, faulty wiring, bad spark plugs or plug wires, low fuel pressure, engine mechanical problems (such as worn out timing belt), clogged air filter or mass airflow sensor, failing starter motor and solenoid assembly, bad ignition switch/lock cylinder assembly or even an ECU (engine control unit) malfunction.

What Should You Do After Replacing Alternator?

After replacing the alternator, it is important to check for any loose connections and ensure that all wires are properly connected. It is also important to double-check that all electrical components like lights, wipers and gauges are working correctly.
