Another One Starts!
I can't drive it yet but it started up first go!http://forums.aussieveedubbers.com/images/smilies/cool.gif
What a joy it was to hear it run.
Can'y wait to drive it some time over the next couple of days.
I do have a problem with the alternator light though:
it stays on even though the alternator is charging properly.
There is a 4 pin connection on my alternator. Should the wire that goes to my alternator light on the dash be connected to pin L or pin D ?
Thanks in advance.
Andy.

There should be:
IG for Ignition supply(eg + when ignition is turned on)
S is for + supply(this can be picked up from the main + Battery supply where the eyelet terminal bolts onto the alternator)
L is for the Charge Light on your dash
The 4th pin could be a number of things depending on what type of alternator, but generally is an AC output which picks up from one of the stator
windings

Thanks for that Paul.
I have my alternator charge light wired up as you suggest and, as I said, my alternator is charging but my alternator charge light stays on
regardless.
Anyone have any ideas why?
Cheers.

Most vw alternators and all vw generators used an external voltage regulator. The Charge light wire picked up from it's own terminal on the origonal
voltage regulator. Then there is another thin wire (Field Wire)that would have went from you regulator to the origonal Vw alternator or generator. A
common mistake is to connect this Field Wire to the new (subaru or other ) alternator as the "Charge Light" wire.
Effectively there is no connection between this wire and your Charge Light, and in some cases your alternator will still charge due a residual
magnetisim in the rotor. So for a period of time it will charge normally. This can be fixed by connecting the Feild Wire to your Charge Light wire to
complete the circuit.(the wires will be were the old voltage regulator is or was, so this is pretty easy)
This may be the case with your conversion, although without seeing how it is wired it is hard to tell. Just to be sure it may be wise to check that
there is continuity between the Charge light wire on the alternator and the other end at the Charge light itself.
If there is continuity and all is how it is supposed to be, it would be a safe bet to say the intenal voltage regulator in your alternator could be
faulty, but if it is still charging enjoy it while it lasts!
