Cadillac DeVille battery not charging as indicated on Cadillac DeVille

Some Cadillac DeVille owners report experiencing issues when the battery warning message appears, often indicating that the battery is not charging. The most common cause cited is a faulty alternator, but other potential issues include damaged wires, corrosion on electrical connectors, and corrosion on battery terminals. Some owners have also noted problems with a bad ground connection or a slipping serpentine belt. When this message is displayed, immediate attention is necessary as it signals a problem with the charging system that requires prompt action. Additionally, an amber, yellow, or red battery light may accompany the warning on the dashboard. To diagnose the issue, owners are advised to test the alternator's output for voltage and amperage and check the wiring connector to ensure proper connection. Inspecting the battery cable terminals for tightness and corrosion, especially the ground cable under the back seat, is also crucial. Furthermore, if the battery is over 5 years old, it is often considered a likely culprit for charging issues in the Cadillac DeVille.
