Why does my car battery keep going flat?

Either the battery can no longer hold a charge, the alternator is not charging it properly, or something is drawing current while the car is switched off. Testing the battery, the charging output and the parasitic draw separates the three, which is cheaper than replacing a battery that was never the problem.

Can you find out why a warning light is on?

Yes. Engine, ABS and airbag lights store fault codes that can be read from the car, and those codes point at the system and often the part involved. The code is where diagnosis starts, not where it ends — the part it names is checked before it is replaced.

My car clicks but will not start. What is it?

A single click or rapid clicking usually means the starter is not getting enough current. That can be a weak battery, a loose or corroded terminal, or a starter motor fault. Checking the battery and terminals first is quick and often solves it.

Electrical repair at Hi-Tech Car Care means finding the cause of a fault before anything is replaced. A car that will not start, a battery that keeps going flat or a warning light that will not clear can each come from several places, and replacing the most likely part first is how people end up paying twice. Batteries, alternators, starters, wiring faults, lighting and sensor problems are all traced back to where they start.

The faults we see most

A battery that goes flat overnight — a tired battery, a charging fault, or something drawing current with the car switched off.
Slow or no cranking, which can be the battery, the terminals, the starter motor or the wiring between them.
A charging warning light, or lights that dim and brighten with engine speed, which point at the alternator or its belt.
Engine, ABS or airbag warning lights, read from the car’s fault codes rather than guessed at.
Lights, horns, power windows and central locking that work intermittently — usually a connection, a relay or a fuse.

A new battery will not fix a charging fault. If the old battery was only a year or two old, the alternator and the wiring deserve a look before the battery is replaced.

Diagnosis first, then an estimate

The fault is found first: the battery and charging system tested, the fault codes read, and the wiring followed where it needs to be. Then you get an estimate that names the part and the reason, line by line, and only what you approve is done. If something else turns up during the repair, it comes back to you before any work is added. Everything goes on the job card against your registration number, so a fault that returns months later can be traced against what was done the first time.
