,## How to test your SQ2‘s battery, step by step,,There are two ways to test the charging system:A- Check the battery indicator (not all batteries have one)B- Use a regular multimeter,A. How to check the battery indicator of your SQ2,Some batteries have a colored indicator that shows you if they have enough power. Like this, if you look closely at the element highlighted in the picture, you can see that if its color is green, that means that the battery charge level is correct, and if it is red, it is not properly charged.,If your battery does not have this function, you should keep on reading to see in what other way you can check its status.,B. How to use a multimeter to check the status of your SQ2‘s battery,• Get the car ready:To check the voltage of the battery, the engine of your SQ2must always be turned 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. In both cases, you should turn the headlamps on for 30 seconds and then turn them off. This will get rid of small voltages which may produce wrong readings.,• Get the multimeter ready:To adjust the multimeter you must turn the selector up to the option that reads 20 V. In that way, it will be placed in the measurement scope you need.,• Measure your SQ2‘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 theblack probeto the negative terminal (-). If these terminals are dirty, you should scratch them softly with the tip of the multimeter until metal and metal can touch.The multimeter will display the “available voltage” of the battery. If the battery is in a good state, the multimeter should show a readingbetween 12 and 13 volts.,• Measure the starting voltage of your SQ2:With the tips of the multimeter in the same position, and without breaking contact, we must turn the engine on and check how much the voltage drops when the engine starts. In other words, when we twist the ignition key. For this step, someone else should help you out. The multimeter should show a reading higher than 9 V, and it will usually bebetween 9 and 11 volts.,• Check the alternator of your SQ2,• With the tips of the multimeter in the same position and with the engine on, the multimeter should show a readingbetween 13.2 and 14.8 volts.,• Now we must turn on all the electrical accessories of the car: lights, air conditioner, defogger, etc. The multimeter should still be between the aforementioned range.,• The next test is to accelerate until the engine is at 3,000 RPM without turning the electrical accessories off. The multimeter should still show a reading between the aforementioned ranged.,• Lastly, accelerate and turn all the electrical accessories off. The multimeter should still show the same reading.,,## Measurements conclusions of your SQ2,,If during this measurement processthe voltage went upout
