The alternator of our 2017 MT EcoSport failed at 122,000 km, after 7 years of daily driving. It happened without warning, as you would expect with failing alternators. Considering the age of our vehicle and the total road distance travelled, this problem was expected to happen. When the alternator fails, it will stop providing the car with electrical power. With the engine running, the car’s system voltage will drop from the normal 13 to 14 volts to about 12 volts or lower, indicating that the engine now relies on the remaining battery power to keep functioning. With the battery not recharging, the voltage will continue to rapidly drop to about 10 volts. The car will then alert you with errors on the dashboard (such as the ABS error light, Airbag error light, and many others) since not enough power is being sent to the various modules. If you do not have a voltmeter display module installed, it may be difficult to instantly recognize an alternator failure. With a failed alternator, you may still be able to start the car 3 to 5 times if you have a good battery, but the voltage will drop rapidly within minutes. As soon as it drops to 10 or 9 volts, the engine will shut down. It is unsafe to drive a car with a faulty alternator since the engine can shut down any moment. In the case of our EcoSport, we were able to start the car four times and drive the car to a safe location for about 10 minutes before shutting down completely.
Using some basic tools, we were able to remove the three screws that hold the alternator in place. The drive belt will need to be removed. We’ve decided to just cut the belt and replace it with a new one since it has been in use for about 40,000 km already. In the interest of completing the repair in the shortest time possible, we simply ordered a replacement alternator from a local supplier and have it delivered the same day. The next day, we installed the replacement alternator and the repair was complete within a few hours.
