If you *are* using a 6v coil without a ballast you have probably burnt the
points, hence the poor running. The ballast is a length of resistance wire
of about 1.5 ohms that starts of white at the ignition switch end and
finishes up white/light-green at the coil +ve terminal. From there it is
extended on to a special terminal on the solenoid that only gives out a
voltage during cranking. This boosts the voltage at the coil during
cranking for ease of starting.
I don't think the one-wire alt is standard for any year, it sounds like a
modern after-market jobbie, what do you do for an ignition warning light?
Two- and three-wire alts have one (or two) browns that go to the hot
terminal of the solenoid and the brown/yellow indicator wire. The electric
temp gauges are shown as having a green/blue to the transmitter.
Green is fused ignition and feeds things like instruments, turn signals,
wipers, heater fan etc.
White/black is used between distributor and coil, can't spot a black/white.
or if that doesn't work try
