Alternator Overheating & Charging System Breakdown in Malaysia | MyMechanic
When the alternator runs hot and the charging system falters—battery light on, dimming lights, burning smell—it’s time to stop safely and protect the vehicle’s electronics.
MyMechanic provides calm roadside triage for Singapore-registered cars in Malaysia, with safe isolation, smart on-site checks, and quick towing to capable workshops.
What to Do Immediately
Reduce electrical load, pull to a safe shoulder, and switch on hazards.
If there’s a hot or acrid smell, stop the engine once parked and keep clear.
Note symptoms like a flickering battery light, squealing noises, or a hissing battery.
Call MyMechanic and share any recent work on the battery or alternator.
Why Overheating Alternators Fail
Belt slip or mis-tension, causing friction and heat.
Bearing degradation, which increases heat and overloads the belt.
Regulator or diode faults, leading to over or undercharging.
Poor grounds or high resistance, making the system run hot and erratic.
