Some alternators have to have the charge light hooked up to allow charging, definitely sounds like that's the case!

Fully charge your battery first, around 13V before doing anything else.


Check earth straps:
1/ Gear box to chassis
2/ Battery earth to chassis
3/ Engine to battery earth (I really must do this!)

Do you mean "Brand spanking new"? If so it sounds like you're not getting enough excitation voltage.

This looks like it's a pretty good read:

Not having a charge light is a BadThing(TM) especially on a dub! (Light comes on and it could have told you your alt belt had snapped and you've lost all cooling)
They're easy enough to wire up - do it. It's two wires and a bulb - POP.
No, not having one wouldn't cause this problem.
