    How do i find out the amperage of the alternator fitted to my 2007 Fiat Ducato Bessacarr E560.
    I am looking to find this info out as ive been reading about a Sterling B2B charger for when i get the money to install solar i would prob fit a B2B charger at the same time.

    I don't remember having to be worried about the amperage of my alternator when I fitted my B2B charger. I just fitted it but it hasn't been used in anger yet. Mine's an X250 3 litre and if the alternator needs to be replaced in due course I'll get the most powerful that will fit.

    There may be a few different outputs depending on original chassis design use.
    A minibus type van will spend hours on motorways etc so doesn't need masses of electrical power but a short haul delivery van May need starting many times each hour so needs to get charge back in the battery quickly.
    Best place to find out would be Google with ALL your vans base details.

    The part number should be stamped on the alternator, may take a bit of finding but easy to find the spec once you have it. Have you rung or emailed Swift or asked on their forum?

    From what i seen from a video Mr Sterling done he said it was pointless buying too big of an B2B charger as your alternator would not be proving enough juice to use of the B2B's potential and you would be wasting money , mind you at about £280 - 300 for a 60 amp version i don't think ill be getting anything bigger than that :)
    but having said that if my alternator was was something like 70 amp , then some of the 60 amp B2B would still be wasted as the alternator has to take some of that 70 amps to run the vehicle / wipers , radio , heater etc.

    I'll see if i can get anything from the alternator tomorrow when i look to see if anything is stamped on it.

    You might struggle to get near the alternator to see anything as its low down at the back of the engine on the offside with sub frames, steering rack, exhaust etc in the way!

    I think the smallest alternator on an X250 is 90 amp most converters fit an uprated one I think the one on Hymers is 160 amp.

    I would expect its nearer to 150amps.
    With today's technology and electrical demands the days of a 65amp Lucas alternator are long dead.
    My car runs a 180amp alternator.

    @Abacist i sort of thought this , but my plan was to lie below the vehicle and take 10,000 pictures of the alternator and hopefully one of them give me some info :D
    @Lenny HB & @pappajohn thanks for the info , i have just went to a parts suppliers website and entered my vehicle reg , then looked for replacement alternators and it listed about 7 of them all were in the range of 110 amp >> 180 amp , except one that had no amperage beside it and it was like half the price of the rest.
    So tip i would say min of 110 amps hopefully :)

    Only way to know what is fitted is to poke your phone at it and click
    Here a 2008 3 litre

    Why fit a b2b charger if you are going to fit solar. The panel will charge both batteries and should the chassis battery drop just c/o on the panel to run off the cab battery. Works for me.

    The solar panels would go in 1st as well at the battery upgrade , the B2b charger would be added then if needed , but at the very least the "factory fitted" charger would need changed.
    I just like to do a lot of research and get opinions :D sure no harm in that.. (y)

    Why does the charger need changed?

    A B2B charger is association with solar is a complete solution - especially if you're considering an inverter.
    We had a Sterling 60a b2b charger in our Bessie.
    The other thing to consider is if you need extra leisure battery capacity.
