Generator / Alternator Swap

I bought a GM alternator with a one wire hookup to install on my 62, Chevy, pickup. The auto parts guy said that all I have to do is run a hot from the alternator to the battery, but that's a problem. First of all, there are three loose wires from the old generator hanging down, and I still have the old voltage regulator to deal with.

Which wire from the old generator do I hook to my new alternator?

What do I do with the other two wires?

What do I do with the wires going to the old voltage regulator, which is no longer needed?

How do I get my generator light to work?

Why has my gas gauge suddenly quit with this installation? coincidence?

The main Wire should be signicanty larger than the other 2 and should be hot all the time, this is the wire you want to use as a feed

What do I do with the other two wires?

Tape or remove

What do I do with the wires going to the old voltage regulator, which is no longer needed?
Remove

How do I get my generator light to work?

I Dont think you can with a 1 wire alternator

Why has my gas gauge suddenly quit with this installation? coincidence?

Dont Know
hope this helps

Your gas guage is another problem. Remove your voltage regulator...tape up each individual wire. The same with your generator. Install the one wire alternator...run one wire from it to your positive battery post or you could run it to the starter solinoid where the batt cable hooks. Thats it. Your generator light will not function anymore.

Thanks!

Thanks for the replies.

Yeah the gauge needle was just sticky. I tapped it and it came to life. lol...

I had it charging but I wanted my generator light working and the voltage regulator gone. I thought about just linking all of the wires as they related to the regulator but the idiot light still wouldn't work so I took it to a local generator shop. They charged me (no pun intendid) 30 bucks and now everything is working perfecly.
