I said months ago that I would post pics when this was done, and I, with help from my dad did it months ago but its lasted since then so I think it was a good simple mod. As my Lucas 15ACR doesn't charge well enough to keep up with essentail components of the car.





It's rated at 75 A so you can draw more than enough from it. It's actaully a mitsubishi made alternator but from a N15 Pulsar (early 90s i think) was reasonably easy to modify. Required a lathe to machine a pulley to fit it as its flat belt but yeah. Mine is in good condition as it charges at 14.7 volts but only problem (and i'm not the only one) The light doesnt work, but I looked at pulsar diagrams and the reason i think is that it requires a resistor to make a load to make the light function, can't really explain but yeah.

I have the same alternator, but I simply took the pulley off the Lucas alternator and switched it over to the Nissan one.......

Theyre a tight fit, arent they

yeah i just cleaned up all the terminals on the lucas one, get 14+v now

Hmm mine didn't fit at all, the thread did not pass the pulley, must be a different pulley, but yeah even machined down yeah its a dam tight fit!, mounting it required two brackets much like a lot of newer cars.

Voltage is not the issue, a good alternator of any kind should and must pull 14+ volts but with all the simple accesories on i was actaully drawing very clost to the rated 34 Amps or wateva, But if your works fine don't change it, i just thought I'd show people what i did.
