Test the vehicle while running with a meter to see what the volts are. AGM batteries, in particular, require a specific charging routine with precise control of all charging parameters. If the system fails completely for some reason, the battery can provide just enough power to keep everything working properly for at least a handful of miles, but it depends greatly on the vehicle and what electric accessories are running.

This is not always the case, but the message is there since the onboard computer no longer sees the vehicle battery being charged. Service battery charging system impalas. How to Diagnose Battery Saver Active. The voltage regulator controls the amount of voltage produced by the alternator. The onboard computer (ECM) detects the voltage from the charging system, which is determined by a battery current sensor. It also helps maintain a constant voltage within the charging system. What Is Battery Saver Active? Even without stop/start, the computers now can have six or more charging modes to reduce battery sulfation, increase fuel economy, keep the headlights shining brightly, and other functions.

Overcharging is much less of an issue these days, but it does still happen. 5 volts when revved. We first addressed Start-Stop Systems two years ago, as they began to appear in the North American vehicle market.

Much like our earlier posts on troubleshooting clutches, and troubleshooting brakes, there are two basic failure modes in the charging system as well: Either it is working too well and over-charges, or it isn't working well enough and under-charges. One of the hardest distinctions to diagnose in the charging system is determining if the battery is starting to go bad, the charging system is under-charging, or there is something draining the battery when the ignition is off. Remove the alternator and take it to your local auto parts store where they can bench test the output - it only takes a minute and is usually free. High powered sound systems, electric cooling fans, and brighter lighting started putting a strain on alternators back in the 1980s. The 4 Amp 12V/6V switchable WeatherTech Battery Charger is designed to lengthen the life of lead acid batteries through its high performance charging functions.
As mentioned before, modern cars do their voltage regulation as part of the engine management in the computer. The main causes are the charging system and the current sensor. Using the Start-Stop equipped 2015 Impala as an example, it will deploy two batteries to meet its electrical demands: a larger, 12 Volt AGM primary battery and a small, auxiliary 12 Volt AGM battery, which powers electric accessories during an Auto Stop event. Twenty-first century vehicles have integrated the voltage regulator into the Engine Control Module (ECM), or Body Control Module (BCM) computer.
