This solution is alkaline so it will neutralize the acid in the corrosion.īattery terminal cleaners are special brushes that are specifically designed to clean battery posts and the inside of terminals. If you notice corrosion on your battery terminals, don the appropriate safety gear and clean the terminals with a stiff-bristled brush and a solution of 1 tablespoon baking soda dissolved in 1 cup water. Typical rust has a reddish tint and may also affect the electrical components’ conductivity. It’s an acidic substance and will eat away a vehicle’s paint and irritate your skin, so use caution. This is often a source of bad connections in an otherwise healthy system.Ĭorrosion is the white, blue, or green product of a reaction that happens with normal use and is accelerated by persistent heat, so hot climates are associated with more corrosion. Corroded electrical components are poor conductors. The positive and negative battery terminals are channels for the electricity, so it’s important not to increase the resistance by covering them with other substances that are poor conductors. If a bad alternator belt is the cause of the battery warning light, it may also cause squealing from the hood when the vehicle is running. They can also be misaligned, too tight, or too loose.

Belts can crack with age or even completely break.

The voltage regulator, the component that limits the output to a safe limit of 14.5 volts, can also be the culprit if it isn’t working as it should. If the voltage is less than 12 volts, the battery light is triggered and you’ll likely need to replace the alternator. The voltage should be between 13.6 volts and 14.6 volts. It’s relatively easy to check the function of the alternator with a multimeter. If this happens then the battery needs to be replaced.īad wiring or bad grounds can also cause the battery to not take or hold a charge. With age, the cells or plates can break and the electrolyte solution can leak. These conventional batteries each have a lead dioxide plate and lead plate submerged in a sulfuric acid electrolyte solution in each of the six cells. Some manufacturers tout a longer lifespan, but the batteries should not be expected to last that long. Normal 12 volt batteries have a 3 to 5 year lifespan. If the battery is having trouble charging, you should notice other symptoms such as dim headlights, clock running slow, or things such as the air conditioner or radio not working. Disconnect the battery before cleaning or closely examining it. It’s a good idea to wear gloves or goggles to protect your eyes if battery acid splashes, and rubber gloves to protect you from shock.

Safety is important whenever working with electrical systems, so check your owner’s manual for general tips. If this occurs, there are a number of potential causes to check out when troubleshooting. The warning light for the battery will stay on if a fault is detected in the charging system. This is a system test that indicates the battery light on the dash, along with any monitored components of the charging system, are working as expected. Top Reasons a Battery Light Comes OnĮvery time the vehicle starts up, the battery warning light should briefly turn on, then back off after a few seconds. Various wires around the engine bay called ground straps connect parts of the wiring harness to the chassis, which help complete different circuits. The current (made of electrons) flows from one post of the battery, through the accessories, then into the other battery post. It is often a component of the engine control unit (ECU). The voltage regulator maintains the desired voltage while charging the battery. Note: Older vehicles may use a dynamo (also called a DC generator) instead of an alternator. This energy is then used to power things such as headlights, power windows, heated seats, radio, air conditioner, DVD players, and cell phone chargers. The alternator takes kinetic energy from the rotating pulley and converts some of this energy into AC power, which is then converted into DC current and stored in the battery. Recharging happens when the crankshaft pulley turns the alternator belt (also known as serpentine belt or accessory belt) which spins a rotor inside the alternator (which is sometimes referred to as a generator). Chemical energy stored in the battery is how the vehicle can be started initially and then as it runs, the battery is recharged.
