wire color
white with red stripe
black ( longest one )

the alternator wire color

red ( batt )

wire comming out of the voltage regulator

white with black stripe

alternator wiring ?

The voltage regulator is usually marked on the plastic insulator over the terminals. I, A, S, and F. The I terminal is spaced 1/4" more away from the other terminals. If you have the reg with the high top, you can replace it with a late 70's solid state regulator, has a cover about 3/4" high.

Connect the F to the fld term on the alternator. Connect A to the Bat+ on the solinoid. Connect S to a source that is hot when the key is on. The I term is not used unless you have a charge indicator lamp. The Bat term on the alternator goes to the Bat+ on the solinoid.
