Battery & Electrical Service at Tiger Garage in Princeton, NJ

A weak battery doesn't always give you much warning. One morning it starts fine, the next morning it doesn't. At Tiger Garage, we test your battery under load to measure its actual cold cranking amps and reserve capacity. That's a more honest reading than just checking the resting voltage with a basic meter. If the battery is getting close to the end of its life, we'll tell you before it strands you, not after.

We also check the alternator's output voltage and current to make sure it's keeping your battery charged properly while you drive. An alternator that's starting to fail can cause all kinds of strange behavior, including warning lights, dim headlights, and even transmission or ABS faults, because those systems depend on steady voltage. Ground straps and terminal connections are part of the inspection too. Corroded or loose grounds are responsible for a surprising number of intermittent electrical problems that are easy to overlook if you're not looking for them.

If your issue is more involved, like a parasitic draw that's killing your battery overnight, or a warning light that keeps coming back after being cleared, we'll trace it down properly. Electrical diagnosis takes patience. We work through it methodically instead of replacing parts at random hoping something fixes it. We work on American, European, and Asian vehicles, so whether you're driving a Honda Civic, a BMW 3 Series, or a Ford F-150 around Princeton, the approach is the same: find the actual cause, explain what it is, and get your go-ahead before any work starts.
