Does Mercedes Sprinter have a smart alternator?

Does Mercedes Sprinter have a smart alternator?

Smart alternators are something that’s coming up more and more frequently these days as vehicle manufacturers seek to get their emissions down to meet Euro 5 & 6 regulations. These are commonplace in T6s, Transit customs, Renault Masters and Mercedes Sprinters, amongst most other new vehicles.

Does the ECU control the alternator?

The Alternator Control function allows for the Elite ECU to control the charging voltage of alternator that supports this function. This is done with a duty signal that is sent to the voltage regulator to alter the charging rate.

How do I know if I have a variable voltage smart alternator?

What you are looking for is a module mounted on or close to the battery terminal (usually the battery negative). This is the battery sensor, if it’s got one of these, you have a variable voltage alternator.

Can you trickle charge a Mercedes battery?

A trickle charger keeps your Mercedes-Benz battery charged, which in turn, results in your battery lasting longer.

What causes alternator to not charge?

The most common reason an alternator is not charging the battery is due to worn carbon brushes or a damaged alternator itself. It can also be caused by a blown fuse or bad wirings. If your serpentine belt snapped off, the alternator will, of course not charge then either.

How does a PCM regulate alternator output?

o The alternator output is controlled externally via the PCM. o The charging system voltage is controlled by the PCM. The generator charges the battery at the same time supplies power for all of the electrical loads that are required. o The PCM simultaneously controls and monitors the output of the generator.

Can I use a VSR with a smart alternator?

However, with a smart alternator, when the output voltage drops to below 12.8V a VSR would disengage, meaning that the auxiliary battery would have significant periods where it wouldn’t be charging, even though the engine would be running (some models of VSR may not engage at all, dependent on the on-board software).
