What does an alternator do?
The alternator is the device responsible for generating electricity to charge the battery. It’s coupled with the engine drive, which means whenever the car is running, the battery is being charged. Without a charged battery there is no delivery of power to the electrical components or to generate the sparks used to combust the fuel in the engine.
How often should an alternator need replacing?
An alternator typically lasts around 7 years or between 100k and 150k miles.
The law, vehicle regulations and your MOT
Without a correctly functioning alternator, your car is unlikely to hold enough charge in the battery to drive for any purposeful length of time. Having said that, the alternator won’t be tested during an MOT, so as long as the battery has enough charge for the engine and other electrical components to run for the duration of the examination, then it can still achieve a pass.
We do not recommend this in any circumstance. If there is a problem with your alternator, you should have it repaired or replaced as soon as possible.
What causes an alternator to stop working correctly?
An alternator might break down due to a bearing failure, preventing the rotor from spinning freely. Fluid leaks or a too tight belt (or a loose belt slipping) can also cause damage and premature wearing.
Symptoms of a malfunctioning alternator
When the battery is flat
If your battery is flat and refuses to accept charge through normal driving, then your alternator could be the problem.
The lights aren’t as bright as normal
If your headlamps aren’t as bright as normal or the function of other electrical components is weak, your alternator may not be supplying as much charge to the battery as it needs.
The battery warning light is illuminated on the dashboard
All warning lights are an indicator that a sensor has detected a failed component or poor operation. A battery warning light could be connected to your alternator performance.

How popular is Toyota in the United Kingdom?
Toyota was the first manufacturer to produce more than 10million vehicles a year, and it has continued to do so since 2012.
There are currently 1.7million on the roads in the UK—a number that has shown consistent growth since their introduction to the UK market.
High-quality motoring—right across the board
Toyota’s current range features luxury saloons, hatchbacks and SUVs, all of which are receiving the steady design upgrade from what were once sensible and steady looking vehicles, into sleeker looking executive sports lines, capable of turning heads at every junction.
Toyota: Market leaders in all-electric and hybrid motoring
Worldwide, Toyota is the market leader in hybrid electric vehicle sales. It’s introduction of the Prius in 1997, the first commercially mass-produced vehicle of its kind, set them on their way as leaders in the field. The UK is no exception, as there are over 80k Prius models on our roads.
There’s more to Toyota than good economy and sensible motoring
As much as the modern market leans towards family SUV motoring and super efficient hybrid fuel economy, don’t be fooled into thinking Toyota is stuck into a single groove.
For those who want more excitement than economy from their driving experience, Toyota makes a selection of cars with much more clout than their sensible city options.
Grab a Toyota GR Supra and you’ll be propelled from 0–62mph in 4.3 seconds using every ounce of its 335bhp. If you want a car that was built for fun and have a spare £52k to lose, then why not put one on your shopping list? As with other Toyota models, it offers great value for the amount of car you’ll be getting.
Toyota’s reliability and reputation
Toyota ranked 3rd place out of 30 car brands in the What Car? Reliability Survey in 2018. They were only just pipped at the post, and by less than 1% for the top spot, by Suzuki; 2nd place went to their very own luxury division, Lexus.
