Problem overview

Some Cadillac Eldorado owners report experiencing significant drops in battery voltage from 14 to 7 volts, which can lead to engine shutdown. This issue may be attributed to several factors, including aging batteries that struggle to maintain voltage levels, faulty alternators that fail to recharge the battery adequately, and poor connections that disrupt the flow of electricity. Additionally, excessive electrical drain from various components can contribute to voltage drops, and extreme temperatures may further impact battery performance. Owners are advised to have their battery, alternator, and electrical connections thoroughly inspected to identify and resolve the underlying issues causing these voltage fluctuations and engine shutdowns.
