What to Look for After Getting a New Alternator Installed
After you install a new car alternator, your task isn’t done. You want to confirm that you completed the installation successfully. The technicians at Massey Yardley CDJR go through a mental checklist after installing alternators to ensure everything functions properly. If you did the installation, use the following as a guide to check your new alternator.
Check the Battery
Your battery should be one of the first things on your checklist after installing a new car alternator. Any installation guide will say that you need to disconnect the battery before installing the new alternator. So, at the very least, you need to make sure that you reconnect it.
But you also want to check the condition of the battery. Start by confirming that it is fully charged. You also want to see if it has the appropriate capacity that your car needs. Remember that a defective battery will cause your car alternator to fail early.
Check the Alternator’s Wires and Cables
One vital step in this guide is taking a closer look at the alternator itself. Specifically, pay attention to the wires and cables that connect it to the battery. You can take care of this part of your checklist while looking at the battery, as the two are connected. Remember that loose connections increase the resistance on the electrical system, potentially damaging the alternator. As such, you need to confirm all the connections are tight before you start your car for the first time after changing the alternator.
Check the Fan and Pulley
The fan and the pulley are next on your checklist. They need to be balanced, as this prevents vibrations that could lead to the new car alternator failing. Remember that a damaged pulley can cause the drive belts to slip and the alternator driving at the wrong speed. Or a damaged fan can prevent the alternator from properly cooling.
A good way to check the balance of these components is to see if the rotor spins freely after unpacking the alternator. If it doesn’t, install the pulley and fan before torquing the pulley unit to 70 to 80 foot-pounds. That should be enough to fix the issue and let you continue with this guide.
Confirm You Used the Right Hardware
Hopefully, you will check the hardware you use to install the car alternator before the installation, but if you didn’t, do it after. Make sure you opted for grade-6 bolts featuring hardened flat washers and self-locking nuts. Avoid lock washers.
Confirm the Speed
One of the final steps on your car alternator checklist is to check its speed. Remember that if the alternator doesn’t reach the correct speed, the regulators won’t start. It may happen while idling. If it doesn’t, hold down your gas pedal and wait for the regulator to turn on.
Finish By Testing the Alternator
The final step of this guide is to use test equipment to assess your new car alternator’s output. Check the system requirements and confirm that the new alternator delivers an extra 20%.
