Any suggestions on whats the best way to put one in ?
VERY important. Most crimps do not properly crimp the terminal ends and over time they will loosen causing you no end of grief tracking down the issue. Crimp and solder each connector and you won't have those problems in the future.How important is soldering the wires?
Or what the new alternators are? Like do they have a voltage regulator built in?
Well that I don't know, as I don't know which alternator you have or what its wiring requirements may be. Post a picture of the alternator connections and tell us what brand, model and amperage it is.How do i wire my alternator then?
Some time back I ran across an article that detailed why you should not use the one wire alternators in a Google search I had done. I no longer remember the exact reasons, but personally I would no longer consider using one on anything other than an old tractor maybe. :good:I haven't done it yet, but a lot of people use a GM style one wire alternator when they upgrade. Instructions are everywhere on the Internet for that swap
