Sprinter Alternator & Charging System
A weak start or battery warning needs a charging-system diagnosis before parts are replaced.
About this service
What the alternator does
The alternator supplies electrical power while the engine runs and helps maintain battery charge. Battery condition, wiring, connections and the accessory drive can also affect charging.
Symptoms to describe
Tell us about warning lights, slow starting, repeated jump starts, flickering equipment or when the battery goes flat. Include recent battery replacement, added camper equipment and whether the problem occurs after the van sits.
A useful service plan
Testing should distinguish a battery, starter, connection or charging fault. We can discuss the findings and the correct alternator specification for your vehicle before a replacement is selected.
