What causes Alternator Failure?
These are the faults we most often find behind this symptom on cars driven in Hyderabad's heat and stop-go traffic:
- Worn alternator brushes after high mileage
- Alternator diode failure causing battery drain while engine is off
- Drive belt (serpentine belt) slipping or broken – alternator not spinning
- Internal voltage regulator failure – battery not charged to correct voltage
- Bearing wear causing alternator to seize and snap drive belt

Frequently asked questions
How do I know if my alternator has failed in Hyderabad?
Signs of alternator failure: Battery warning light on dashboard, headlights dimming especially at idle, battery draining overnight despite driving regularly, electrical accessories working sluggishly, and the smell of burning rubber from a slipping alternator belt. Metre Per Second tests alternator output voltage (should be 13.5–14.5V) for free with any service visit.
Can I drive with a bad alternator in Hyderabad?
Driving with a failed alternator in Hyderabad is dangerous — your car is running purely on battery power, which will last 20–45 minutes before completely dying. In Hyderabad traffic, you could be stranded in a dangerous location. Metre Per Second recommends calling for pickup if the battery warning light comes on. We service alternators for all car brands at our KPHB workshop.
