To sum it up: What should you measure to check the charging system of your Equinox? If this increment was below the range, the alternator is probably damaged. If during this measurement process the voltage went up outside the mentioned range, the voltage regulator must be damaged. The multimeter should still show the same reading. Lastly, accelerate and turn all the electrical accessories off.The multimeter should still show a reading between the aforementioned ranged. The next test is to accelerate until the engine is at 3,000 RPM without turning the electrical accessories off.The multimeter should still be between the aforementioned range. Now we must turn on all the electrical accessories of the car: lights, air conditioner, defogger, etc.With the tips of the multimeter in the same position and with the engine on, the multimeter should show a reading between 13.2 and 14.8 volts.The multimeter should show a reading higher than 9 V, and it will usually be between 9 and 11 volts.

The multimeter will display the “available voltage” of the battery. If these terminals are dirty, you should scratch them softly with the tip of the multimeter until metal and metal can touch. Measure your Equinox‘s battery while the engine is off: After you turn the multimeter on, connect the red probe to the positive terminal (+) of the battery, which is usually marked in red color too, and then connect the black probe to the negative terminal (-).In that way, it will be placed in the measurement scope you need. Get the multimeter ready: To adjust the multimeter you must turn the selector up to the option that reads 20 V.This will get rid of small voltages which may produce wrong readings. In both cases, you should turn the headlamps on for 30 seconds and then turn them off.

If the engine is on, you should turn it off and let it rest for at least 5 minutes so that its electric charge stabilizes.

Get the car ready: To check the voltage of the battery, the engine of your Equinoxmust always be turned off.
