Just picked up a new 1 wire alt. (free), too install on my 64 Chevelle, what do I do with the voltage regulator that is in place at this time (unplug it, leave pluged in, etc.) and the hot wire that has to be ran to the new alt. is it suppost to be hot all the time or only when motor is running, Thanks for any info.

When an alternator is converted into a "1 wire",Im pretty sure you need to change over to a voltmeter & get rid of the ammeter.Do some checking around first before you burn up some wiring.Either way,you need to run at least a 10 gauge wire from the alternator,directley to the battery.You could also get away with running the wire to the battery cable post on the starter.Yes,,the wire is hot all the time.

You also need to bypass the external regulator with a aftermarket plug. You can find one at http://www.lectriclimited.com/. Item VAK6368SI listed under '67 Chevelle.

Depends on the current of the alternator. If it's just a 60A or so unit then you connect the wire that goes to the back of your old alternator to the new alternator. This makes the regulator and other wiring plug useless. The regulator won't hurt being there but you might as well remove it and tie back the wires.

If the alternator is a higher current unit then you need to upgrade that main wire that connects to the back from the factory 10 guage size to a size suitable for the alternator current.

Thanks For The Info, I will dig into it this weekend. Thanks smile.gif

I put a one wire 100amp alt. into much 350 malibu and just hooked up the one hot wire.I didn't change anything. Could this cause problem down the road because everything seems good right now?

Year one carries a cap to plug off the connector that goes to the voltage regulator. Also Mad Electrical has some great info about GM Eletrical systems, along with simple upgrades. Check it out at www.madelectrical.com. (http://www.madelectrical.com.)
