Electrical problems can leave you stranded without warning—dead batteries, no-start conditions, flickering lights, random warning messages, or strange glitches in vehicle systems. Titan Auto Tech in Castle Rock, CO provides professional electrical and charging system diagnostics to fix the real cause, not just the symptom.
Modern vehicles are rolling computer networks. Replacing parts without testing is how people waste money. We diagnose first—then repair with precision.

Your battery is only one piece of the system. Charging and electrical issues may involve:
- Battery health and reserve capacity
- Alternator output and voltage regulation
- Starter amperage draw

We support personal vehicles, trucks, SUVs, and fleet vehicles. For extensive electrical work, Titan offers loaner vehicles (availability-based) and financing options.
Common Electrical & Charging Problems We Diagnose in Castle Rock
Why does my battery keep dying?
Repeated battery failure is commonly caused by parasitic draw, alternator failure, poor connections, or a battery that’s not the correct type/spec for the vehicle.
Titan Auto Tech performs battery and charging tests plus parasitic draw testing to identify the exact drain—so the fix sticks.

What is a parasitic draw and how do you find it?
A parasitic draw is an electrical load that continues after the vehicle is off, slowly draining the battery. Causes can include stuck relays, modules that won’t “sleep,” aftermarket accessories, or wiring faults.
We measure draw, isolate the circuit, and confirm the faulty component or wiring issue before repairs.
Why won’t my car start but the battery is new?
A new battery doesn’t eliminate starter issues, alternator problems, cable corrosion, poor grounds, or module-related no-start conditions.
Titan Auto Tech tests starting system amperage, checks voltage drop, inspects connections, and verifies module commands where applicable.
Why is my battery light on while driving?
A battery/charging warning light usually indicates alternator output or voltage regulation issues. Driving too long with a charging fault can cause stalling and leave you stranded.
We test alternator output under load, inspect belts (if applicable), check wiring and grounds, and confirm the true cause.

Why are my lights flickering or my electronics acting weird?
Flickering lights and electronic glitches often come from unstable voltage, weak grounds, alternator ripple, failing modules, or wiring issues.
Titan Auto Tech tests charging stability, inspects grounds, and evaluates module communication to restore reliable operation.
Can electrical issues cause random warning lights?
Yes. Electrical faults can trigger warnings for ABS, traction control, power steering, transmission systems, and more—because these modules rely on stable voltage and network communication.
We diagnose system-wide electrical health instead of chasing warning lights one by one.
