I find a lot of the one wire alternators need revved up to start charging. Basically the circuit is completed through the charge light in the dash on regular 3 wire setup, try that. I also used a 4 gauge looped battery cable from Canadian Tire from the battery to big red battery terminal on the alternator.

Yep I have 4 gauge looped from alternator to battery. The old is SI altenator and the new one is CS

So do I have to hook up the 2 wire again?

It may not make any difference but it should also work as a regular alternator and hopefully charge better. Not a fan of the one wire alternators because of the rev it to charge design.

Well I ordered a pigtail that converts SI to CS alternator. Now with that, do I hook that back up to the starter or jump to the post on the alternator? Would that cause issues with the charging circuit both ways?
 
Found a pigtail for a CS alternator. Was the one wire only so I added the second wire and jumped it to the battery post on the alternator. It's charging now but the guage says around 10 volts. I am hoping it's just the guage. Will pick up a tester and see. My oil pressure gauge doesn't work either. I have a new sending unit so that's not the issue.


Took her for a rip tonight on the highway, went for about 20 minutes. I am very impressed, hammer on her and the front end noses up. This is still the 273 gearing, I haven't put in the 8.5 342 posi. Will be interesting with the 342
 
Correct, they interchange.

Was your assumption about the low voltage reading correct? Would it start after you got home.
