Hi everyone
I've got an 1963 series 2a petrol negative earth which
has still
got a dynamo which i want to swap over to an alternator system.
Has any one got a list of parts i would need to obtain and a procedure for
fitting them.

Thanks Dave

Are you sure it's negative earth? IIRC 1963 Series were still +ve earth.

Have a search on the web - there's loads of info about the swap,
including wiring etc - it's not a difficult job.

You will need an alternator, connecting plug, drive pully, mounting
bracket for the mecanical bits. I used a large terminal block for the
connections mounted on the bulkhead where the regulator box used to go.
With a bit of carful thought you can use the existing wiring loom. I
think I used the field connection to the dynamo to operate the ignition
light.

You could, although it's not really heavy enough to cope with the
current an alternator puts out.

They were, but it may well have been changed - very simple procedure with
the only physical changes being the battery terminals.

And ammeter connections

Thanks for your help
I will start gathering bits

Yes, of course, thanks for the correction.

Not much of an issue really the ancillaries will only draw the same current
( unless you go pots for rags and stick a load of spots and stuff on ) the
only section of wire that gets an extra load is the connection to the
battery so that can easily be upgraded or just put a secondary on. I did a
few conversions on early Mini's ( showing his age) and for ease retained the
regulator ( can't remember how we did it ) but they could and would expire
after a time .Worth looking about for size of drive pulley to use so you're
not running the alternator at the wrong speed.

I also converted a couple of series LRs, IIRC I just bought the
alternator mount pillar for the bottom bracket, jumped the charging
light straight from regulator to alternator and piggy backed the
alternator output to the battery spades on the regulator plus swapped
the battery terminals removing the field lead from the regulator.

It was all over twenty years ago now so don't trust my memory!

With age comes wisdom and experience but usually I can't remember what the
bloody question was!

I just put on the smallest diameter pulley I could, as I need more output at
low RPM (no such thing as high RPM on a Series anyway) as my need was to
ensure power to the Kenlowe fan that comes on when I'm spraying, with the
engine doing no more than a fast tickover.

http://www.series2club.co.uk/ has a diagram and full instructions, plus a
lot else of interest to a S2 owner. Good site and great forum.
