How do you check the alternator on my 1988 Toyota MR2?

To check the alternator on your 1988 Toyota MR2, first ensure the battery is fully charged and the connections are clean and tight. Start the engine and use a multimeter to measure the voltage at the battery terminals; it should read between 13.8 to 14.4 volts if the alternator is functioning properly. If the voltage is lower, the alternator may not be charging the battery effectively. Additionally, listen for any unusual noises from the alternator and check for signs of wear or damage to the belts and connections.
