To get around that issue with your charge circuit you just need to connect a 39ohm resistor in parallel with the charge warning led. That will approximate the resistance of the bulb (about 38ohms). You should then find that the alternator gets sufficient seed voltage to operate as it would with the bulb but will retain the functionality of the charge warning light. Mark Miles

It would be better to connect it to an ignition circuit if you have to. I've always found that even without the warning light connected there is enough residual magnetism in the alternator for it to self excite about about 3000rpm and then work fine after that. My 2+2 does that because i changed the warning light to an LED but it's not really a problem. Maybe not the case on a brand new alternator though.
