How To Test An Alternator Testing The Voltage Regulator Diode Rectifier Unplug the voltage regulator. that’s the electrical connector on the alternator. set your multimeter to the diode test setting. the diode test on a multimeter is marked with a diode symbol. now, locate the terminal on the alternator where the positive battery cable was attached before you removed it. This video will cover the following how to test an alternator using multi meterhow to replace an altern.

A bench test checks diodes and internal regulators to gauge the alternator’s ability to produce its rated voltage and current. steps to bench test an alternator. fit the alternator into the bench test machine and connect the drive belt. identify each connection at the rear end of the alternator. Another, riskier method to check the alternator involves disconnecting the battery from the car altogether; with the car running, disconnect the battery and see if the car continues to run.if it. The voltage reading should increase to around 13.8 to 14.4 volts if the alternator is functioning correctly. diode test: set your multimeter to the diode testing mode (usually represented by a diode symbol). connect the multimeter's leads to the alternator's diode terminals (refer to your vehicle's repair manual for the exact location).
Bad Alternator Diode Symptoms Causes And How To Test Another, riskier method to check the alternator involves disconnecting the battery from the car altogether; with the car running, disconnect the battery and see if the car continues to run.if it.

Press each probe to the correct terminal, touching negative to negative and positive to positive. your multimeter and battery are probably both color coded, so the negative terminal and probe will be black while the positive terminal and probe are red. if your vehicle has a battery that is tucked away, like under the rear seat or fender well. Get a cheap voltmeter. with the engine off, battery voltage should be between 12.5 and 12.8 volts. if it’s below that, charge the battery with a battery charger before you conduct the test again. then start the engine and check for increased voltage readings. if you see higher readings, chances are the alternator is good.
