Speedmaster 1 Wire Altenator

[noreastfish]

I bought a 100 Amp speedmaster ! wire alternator for my 70 Challenger. I know that it's wired directly to the battery. My question is what do you do with the original wires from the alternator and the voltage regulator?
Also wondering since the alternator is going directly to the battery if I need to bypass the original amp gauge that came in the car. I have heard people say bypass it and others say it is not problem. Any help is greatly appreciated.

I would definatley bypass the amp gauge .
The rest of the wiring can be removed , the dark blue circuit can be retained as it is 12v power in run position .
The green wire just ground the alt field to the regulator so there is no need for that at all .

Since I went to  1 wire I have a battery drain.  I am suspicious the field wires are the problem? 

Any ideas?

disconnect the alt when sitting & see if the drain stops

Okay, if it does stop, what would that tell me?

I put one of these on my corvette and I love it! I plan to upgrade my Mopars with them as well. According to the instructions for the GM unit, you can remove the extra wires as they are for the external voltage regulator. It no longer needs the external regulator since it is internal but the instructions mentioned that if you have an alternator idiot light, it will stay lit if you leave them disconnected. There was some sort of direction on how to cure this. I didn't have that to contend with so it didn't matter to me at the time.

When I do my Mopars, I plan to run the heavy wire to the solenoid rather than the battery since it accomplishes the same thing and looks cleaner. Some one in here once suggested bypassing the ammeter inside by connecting both wires onto the same gauge terminal. I liked that idea and did it to my cars. Better than taping off loose wires and hoping nothing ever shorts out.

These alternators are fantastic as they automatically start charging at 1500 rpms and once activated, stay charging until the speed drops below 500 or so other ridiculously low number. Best part though is it produces maximum current at idle and it's consistent throughout all rpms. No more headlight or heater fan power drop off at idle. Of course the extra capacity is nice if you have lots of power needs like electric fans.

AN internal load in the alt  that is not shutting off
