    I know some in the H A M B group did an generator to alternator conversion. My alternator and most of the wire are installed. My question is what do you use for the 10 ohm resistor ? and where is the best place to install it?
    If somebody has an picture would be great.
    Any help is appreciated. I want to get the beast back on the road!! But I still have to repair the bloody torque ball

    something like this would work

    It needs to go in that wire somewhere between the alternator and the ignition switch, the place is up to you. It can be taped into the wiring harness if you'd like.

    Thanks Jim. I was looking at something like this too, just was wondering about the small wire.

    If the car has a GEN light, just connect it to the light, you should be ok without a resistor. If no light, then the resistor will work. Or put a light bulb under the hood somewhere. A light bulb is a resistor, you know.

    If you're using a standard gm alternator, there's a two wire plug on the side and a main power port. Hook up an 8 gauge from the power port to the positive battery cable at the starter, on the plug, you can either hook up the red wire to the power port on the alternator, or, as I prefer, to the fusebox in the car, this wire tells the regulator how much current to put out. The white wire energises the alternator, or more correctly, when you switch the key on, sends power to the alternator....telling the alternator the car is live and ready for it to charge. Hook this wire (white) to the acc side of the ignition switch, so that when turned on, power goes to the alternator, BUT, when running, the alternator sends power back through this same wire to the switch. Hook it up anywhere else, the car will continue to run after you shut the switch off, but the acc side of the switch is separate from the run side and will work as it should if wired this way. It's how I wire my cars.

    I don't know if the 59 Buick still has the gas pedal starter switch on it, but if it does wire it like this.

    Yes it has, I have the same wire diagram. I just was wondering how the set up with the 10 ohm resistor is

    Ok, I give it a try without the 10 ohm resistor. Will see what happens.
