How many wires are connected to alternator on 1966 mustang which color goes where?

There should be three wires attached to back of the alternator of a 66. You should have a black wire with a red stripe hooked to the GRD post, a black wire with a yellow stripe hooked to the BAT post and a white wire hooked to the FLD post. The black wire with the red stripe is the ground and splits off with one end bolting to the engine block on the same bolt that holds the negative battery cable to the block, the black wire with the yellow stripe goes to the hot side of the starter solenoid, and the white wire goes over to the F post on the voltage regulator.
