Alternator and Starter Repair for Proton
Starting or charging problems on a Proton need a full electrical inspection before repair costs are known. A starter or alternator fault can mean anything from a worn brush to a failed component, and the price depends on what the inspection finds.
Should you repair a clicking starter now or wait?
A starter that clicks but does not turn the engine over usually means the starter motor is failing or the battery is too weak to drive it. Waiting risks leaving you stranded — a completely dead starter stops you from starting at all. If the battery is the cause, it will keep draining and make worse starters wear faster.
What does a charging warning light mean on your Proton?
The light tells you the alternator is not charging the battery while the engine runs. This usually points to a worn alternator, a broken belt, or a failed regulator. Ignore it and the battery empties, which kills the starter and forces a tow.
What does the inspection check?
We test the starter motor itself, measure the charging voltage from the alternator, and look at the wiring and connections for corrosion or damage. This takes about an hour and tells us whether to replace the starter, alternator, or both — or if the fault is simpler, like a loose cable.
Why does a Proton battery keep going flat between drives?
The alternator may not be replacing the charge lost during starting, or a component is drawing power when the engine is off. A parasitic drain is harder to spot but the inspection can find it. Getting this wrong means a new battery does not help.
Starting and charging repair options and costs
| Fault | Likely cause | Cost range |
|---|---|---|
| Clicking when starting | Weak battery or worn starter | Inspection needed |
| Engine will not crank at all | Dead battery or failed starter | Inspection needed |
| Battery keeps going flat | Alternator or parasitic drain | Inspection needed |
| Charging warning light | Alternator or belt failure | Inspection needed |
Proton specifics
Saga and Persona models commonly come in with battery and charging faults, especially if they are used for short drives that do not let the alternator fully recharge. X50 and X70 owners also report clicking starters after years of use. A proper test settles whether the alternator, starter, or both need replacing.
Frequently asked questions
Can a Proton starter be repaired or does it always need replacing?
Most starters that fail completely must be replaced. The inspection checks whether the motor brushes are worn or whether the solenoid has failed. A worn brush starter cannot be reliably rebuilt on the workshop bench, so replacement is usually the right choice. We confirm this before you approve the cost.
How do I know if the battery or the alternator is the problem?
A battery test and a voltage check while the engine runs will separate them. If the alternator is charging correctly but the battery is weak or old, battery replacement is the faster fix. If the alternator output is low, the alternator itself has likely failed. The inspection confirms which one.
Will a new alternator fit my Proton without modifying anything?
Yes. The alternator mounts in the same place and the belt pulley matches the engine. We confirm the part matches your model and year before ordering. Once fitted, the charging voltage test confirms it is working correctly before you drive away.
What should I tell the workshop when I book an alternator or starter appointment?
Tell us the exact model — Saga, Persona, X50, X70, or S70 — and describe the fault: clicking when starting, battery light on, or battery going flat between drives. If the car will not start at all, mention that. This helps us schedule enough time and have the right test equipment ready.
