Car Battery Draining Overnight?

If your car battery keeps dying overnight, you may be dealing with what’s known as a parasitic amp draw—an electrical issue where something in your vehicle continues pulling power even after the engine is off. Modern vehicles have many modules that “sleep” when the car is shut down, but if one of them stays awake, or if a component is malfunctioning, it can drain your battery while your engine isn’t running.

We provide on-site parasitic draw diagnostics in Weatherford, Granbury and surrounding areas to track down exactly which circuit is causing the drain. This process involves connecting specialized diagnostic equipment, monitoring current flow through the electrical system, and then isolating each circuit one at a time. By pulling fuses, checking relays, and analyzing live data patterns, I can identify whether the issue is coming from a stuck module, a failing switch, a shorted wire, an aftermarket accessory, or another hidden cause.

If your battery keeps going dead overnight—or even after a few hours—this is a problem that won’t fix itself. Let us come to you, diagnose it accurately, and help you put an end to the guesswork and frustration!
