Angry ALTERNATOR Help!!!!!

Okay i have a question i have a 69 prostreet camaro. Well it had a one wire ultra mini alternator on it. It was only producing 55amps. well i went with a a one wire internal regulator style alternator. well i hooked it up the same way and i am getting nothing back from the alternator i went and had it checked and they said it was bad so i bought a new one went home and still nothing. It has a 4 prong connector on the side. i know i have to to use the terminal on the back going to the battery. But my question is do i have to use any of the four prongs to maybe activate the alternator at a certain RPM? i have been looking thru the forums and seen a little of this and that but haven't seen nothing to assuring of what i could or need to do. i seen one thing about a guy with a street/strip car with a new OE style alternator and he was talking about making a jumper. But i am not sure what i need to jump. Can you Help me ??? Also i am running JUST A SINGLE V BELT PULLEY FROM THE CRANK TO ALTERNATOR. I HAVE A ELECTRIC WATER PUMP, FAN AND SO ON.

Is the new alternator a one wire alternator or a stock one. One wire alternators have to be reved to be started, at what engine RPM they will start depends on your alternator pulley to crank pulley ratio. sometimes it can be quite high ( 3000+ RPM) If its a stock one, then the connector has to be used. A 4 prong connector alternator is a CS130 series. Only 2 of the terminals would be used in your app. Post back on which type of alt you have, then we can go from there.

Re: ALTERNATOR Help!!!!!

Here is the basic stuff on CS130 wiring.

Re: ALTERNATOR Help!!!!!

S = a heavy gauge wire to the battery supply (horn relay)
F = not used
L = a small gauge wire that comes from the idiot light and energizes the alternator
P = not used

The terminals should be marked on the alternator. Again, is any or the original wiring for the charging system still there? If so some of it can be used, if not, you will have to make new ones. Terminal "L" has to have a small resistance inline on the wire feeding it. On idiot light cars the resistance is the bulb and a resistance bypass wire (incase the bulb burns out). Original gauge cars only have the resistance wire. For original wiring, this wire ( a brown) originally went to terminal 4 at the voltage regulator.
