Battery vs starter motor: how to tell the difference

Rapid clicking when you turn the key

Usually a flat or failing battery. The solenoid is trying to engage but there is not enough current to spin the motor.

Single loud click with no crank

Usually the starter motor solenoid engaging but the motor not spinning. Points to the starter motor or solenoid rather than the battery.

Slow laboured cranking

Can be either a weak battery or a starter motor drawing excessive current. A charging system test will confirm which.

No sound at all when the key is turned

Could be a completely flat battery, a blown fusible link, a faulty ignition switch, or a starter circuit wiring fault. A diagnostic test is needed to pinpoint the cause.

How to get a fair price for a starter motor replacement

1. 1. Ask the garage to confirm the fault with a starter circuit test before replacing any parts.
2. 2. Confirm whether a new or reconditioned starter motor is quoted and that it comes with a 12-month warranty.
3. 3. Ask whether the battery has been tested at the same time, as a weak battery can mask a starter motor fault and vice versa.
4. 4. Get at least two quotes before booking, particularly if the first quote is from a dealership.
5. 5. Confirm the total labour time included in the quote so you can compare like for like.

Common questions about starter motor replacement costs

What are the signs of a failing starter motor?

The most common symptoms are: a single loud click when you turn the key with no engine cranking; a grinding or whirring noise when starting that does not result in the engine firing; intermittent starting where the car starts fine one day and not the next; and a slow, laboured crank that feels like the battery is flat even after a charge. A clicking sound with a healthy battery almost always points to the starter motor solenoid or the motor itself.

How do I know if it is the starter motor or the battery?

A flat battery will typically produce a rapid clicking sound or very slow cranking. Measure the battery voltage with a multimeter: above 12.4 V at rest suggests the battery is healthy. If the battery reads well but you still get a single loud click or no crank, the starter motor or its solenoid is the likely cause. A garage can confirm this with a starter circuit test. Do not assume a jump-start proving the car will start means the battery is fine: a faulty starter motor can sometimes be triggered by the surge of current from jump leads.

Can I drive my car if the starter motor is failing?

No. A failing starter motor will eventually leave you stranded and unable to start the car. There is no safe temporary fix. If the car is starting intermittently, arrange to get it to a garage while it is still starting. Do not rely on push-starting as a long-term solution: it is only practical with a manual gearbox and is not possible on vehicles with automatic transmissions.

Should I fit a new or reconditioned starter motor?

A professionally reconditioned starter motor is a cost-effective and reliable option commonly used by independent garages. A quality reconditioned unit with a 12-month warranty will typically perform identically to a new part. The saving over a new OEM starter is usually 30 to 50 percent. Avoid very cheap units from unknown suppliers as the quality of remanufacturing varies significantly.

How long does a starter motor replacement take?

Most starter motor replacements take one to two hours. On some vehicles the starter is easy to access from above or below the car and the job takes under an hour. On others it is buried behind ancillary components and requires partial disassembly, taking up to three hours. Ask the garage to confirm the expected labour time before booking so you can budget accurately.

What causes a starter motor to fail?

Starter motors most commonly fail from age and accumulated use. Internal brushes wear down, the solenoid contacts pit and corrode, and bearings wear. The motor is only used briefly each time you start the car but it draws a very high current (often 100 to 200 amps) each time, which creates significant heat and electrical stress. Frequent short journeys with many cold starts, excessive heat from a nearby exhaust manifold, or oil contamination from nearby leaks can all shorten starter motor life.

What affects the cost of a starter motor replacement?

The main factors are: the make and model of your car (starter motor access and parts prices vary significantly); whether a new or reconditioned unit is fitted; your location (London and South East are typically more expensive); and whether you use an independent garage or a franchised dealer. Independent garages are consistently cheaper for this repair with no difference in quality when the same parts are used.

Will a faulty starter motor cause an MOT failure?

Not directly. The MOT test does not specifically test the starter motor. However, if the car cannot be started for the test, the MOT cannot proceed. If an intermittent starter fault means the car will not start reliably, get it fixed before your MOT appointment to avoid a wasted booking fee.

How long should a replacement starter motor last?

A quality starter motor, new or properly reconditioned, should last well beyond 100,000 starts under normal conditions. In practice, most drivers never replace the starter motor twice on the same car. Vehicles with stop-start systems place far higher demand on the starter and may use a specialist heavy-duty unit designed for thousands of start cycles per year.
