    Thanks for all the replies guys,

    Well its a few months later and I have my new 100 amp model from the Disc and ready to fit it to the Defender
    However… the old one has two connections (B+ and D+) and the new one has three connections (B+, D+ and W).

    Does anyone know if there is any special way to wire this up?

    Thanks


    Craig

    I've done it on my home jigged Bosch alternator out of a Magna Verada but I dunno about the Marelli one. Bloody stupid complicated italian rubbish! Splitting those required unsoldering of all the coils if they are anything like the original I had.

    This shows how I did the W wire. It's a simple AC pickup from ONE of the field coils.

    BTW - the W terminal is the source for you're tacho. The others are the main output and the battery sense terminals.

    the extra one is for the tacho

    on the old defender one it has a rubber cover over the unused tacho fitting point which is a screw on fitting not a blade (or mine did)
