Warning lights
- A steady check engine light needs attention soon. A flashing one is more serious and can damage the catalytic converter, so avoid driving further.2
- The battery light on the dash is often a sign the alternator needs replacing.3
- A lit check engine or battery light, dim headlights or failing accessories are all reasons to check the battery.4
Starting and charging
- A single click, or nothing, when you turn the key with a charged battery points to the starter.2
- Starting on a jump and dying soon after points to the alternator.2
- Lights that dim or get too bright are a common alternator symptom.3
- NHTSA advises having a mechanic check the battery and charging system.5
Diagnostics and Nevada emissions
The OBD system is also how Nevada tests emissions: the state uses OBDII for 1996 and newer light-duty gasoline vehicles.6 A check engine light that is on can stand between you and a registration, so it is worth reading the code and fixing the cause.
The code points to the system that set the light. The repair comes from checking that system: wiring, sensors, ignition, fuel or emissions parts. If the light is about how the engine runs, see Engine repair.
Heat is a battery's enemy
Summer heat does more damage to a battery than winter; batteries in the southern U.S. last on average 17 months less, according to Consumer Reports as cited by AAA.7 Excessive heat and overcharging are the two main reasons batteries die early, because heat evaporates the battery fluid.4
AAA calls heat and vibration a battery's two worst enemies and says any battery over three years old should be tested.8 In a valley that averages about 78 days a year at 100°F or hotter,9 test it before summer.
