the guy that owned this thing before me screwed up the wiring big time. loose ends, wrong wires, ect. anybody know where i can get a wiring diagram for a 67 barracuda 273 2bbl? also, what is the significance of an electronic voltage regulator?
 
it helps better at idle and throughout the rpm range. the later style 2 spade alts have their voltage regulated going into the alt rather than coming out like the old 1 spade styles. it is a good upgrade.
 
which voltage regulator would i get for the later model alternator(2 spade), the constant output one?

Mopar recommends use of the constant output regulator with their electronic ignition. If you still have points I wouldn`t worry with it. On the alternator ,connect one field wire to a ground on the alternator case.
 
so hey, what r the consiquences of using the stock regulator with the electronic ignition? sorry, im electronically challenged

The old regulators are basically a point type regulator and will not let you realize the full potential of your electronic system. The system will run okay with the original regulator but better with the constant output reg. The 3690732 reg.is a constant output and lets the electrons flow freely.
 
ok, so my car didnt have the negative cable hooked up when i got it. where do i ground it?
 
Regarding regulators if you purchase a replacement regulator for your car from the local parts store it will have solid state guts in it (to expensive to make a mechanical regulator compared to an electronic one).

I have no idea why Mopar Performance refered to their electronic regulators as "constant voltage". Every voltage regulator is essentially a constant voltage device. In order for current to flow from the alternator to the battery the output potential at the alternator must be higher than the battery. With the battery nominal voltage being 12.8 volts regulators are typically designed to keep the alternator output voltage at 14 volts +/- .1 or so.

The only thing that makes any sense is that a mechanical regulator because of the points generates a lot of electrical noise in the system and could potentially damage the solid state devices in the electronic regulator.

The negative cable should be attached to the block at whatever convienient point the cable will reach to. You also should have at least one ground strape that goes from the block to the body of the car to ensure your ground system is good.
