Battery, starting and charging

A no-start is not always the battery. We test the battery’s condition, the starter’s current draw and the alternator’s output, and we check cables and grounds. If the battery keeps draining overnight, we measure parasitic draw to find the circuit that is staying awake.

Wiring and module faults

Modern vehicles run dozens of control modules on shared networks. We use wiring diagrams and test equipment to trace opens, shorts and poor connections, and we check for water intrusion and corrosion, which are common near the coast.

Questions we hear often

How long does a car battery last?

Most last three to five years. Heat, short trips and long periods parked shorten that. We can test yours and tell you how much capacity is left.

My car won't start. Is it the battery or the starter?

A slow crank or rapid clicking often points to the battery or its connections. A single click with bright lights can point to the starter. Testing takes the guessing out.

Why does my battery keep dying?

Common causes are an aging battery, an alternator that is not charging fully, or a parasitic draw from a module or accessory that stays on.

Do you work on hybrid and EV electrical systems?

Yes. We service hybrid and electric vehicles. High-voltage work follows specific safety procedures.
