Battery, Alternator & Starter motor
Not so long ago you could usually tell if your car’s battery was failing. Typically the headlamps would not shine quite as bright, or the starter motor would crank the engine over a little slower than normal. It was a more simple time for the garage too, as most battery and charging system faults could be diagnosed using little more than a voltmeter and a “drop tester”
Things have moved on however. A modern car uses many computers, each system having its own ECU. The ECU and associated components are very sensitive to voltage fluctuations in your car’s electrical system. Many seemingly random and unrelated problems often turn out to be battery or charging system related.
Here at RALLY TEC we can perform advanced diagnostic tests to verify the health of your battery, starter motor and charging system. Testing can include such things as alternator ripple current testing, cranking current profile testing, and alternator load tests, as well as measuring the battery’s performance against its original specification.
A typical system test will include:
- Battery testing
- Alternator testing
- Starter motor testing
- Starter solenoid testing
