Why you should have an Electrical System Analysis
A steady supply of current is crucial to operating the highly sophisticated electronics in today’s vehicles. Lack of current or fluctuations in the supply of current can:
- cause the “Check Engine” light to come on
- cause poor performance or stalling
- result in malfunctions of the computers that operate your vehicle’s climate control, ride control, and ABS brakes.
Diagnosing the starting system requires several different tests. A “starter draw test” determines if the starter is drawing more amperage than is needed to turn over the engine. A “circuit test” determines if all the other components are working and the voltage is present when and where it is needed.
Your vehicle’s battery must maintain enough voltage to turn the starter and overcome the engine’s resistance. That’s where your vehicle’s charging system steps into place. The alternator, drive belt, and voltage regulator, that make up the charging system, work together to supply enough voltage to run your vehicle’s accessories and continuously recharge your battery to keep it from going dead.
A battery goes dead because of electrical drain caused by one of the following:
- a short circuit
- under charging due to a bad drive belt, alternator or voltage regulator
- over-charging, which can cause serious and expensive damage to highly sensitive computer electronics.
You need the right equipment and an experienced technician to make an accurate diagnosis of your electrical system, without causing possible further damage to sensitive electronic components.
Before just replacing the battery, have a charging system test to be sure nothing else may have caused the battery to fail.
