One field wire gets a switched 12v lead, the other goes to the voltage regulator....
EDIT Is this a 70 or later vehicle or a 69 & older vehicle....

probably a wiring problem. Depends what car and year. 70 and earlier use single field alternators with old style mechanical regulators. 71 up most use dual field alternators and electronic regulators. You need the electronic regulator an 2 field alternator. BTW - make sure you have a good ground from the battery to the body ...not just the engine...and a good ground from the regulator to the body. Some auto parts stores cheapie regulators have been known to NOT make good grounds to the body bcus of the coating they use. And on an associated note... my NEVER ENDING 66 coronet project stopped charging too and I cant figure out why!  But Ive got a pretty good idea its the battery to body ground ...in that...I DONT HAVE ONE at the moment!!  Its got one of those new fangled replacement regulators that LOOK like the old mechanical one but with electronic guts. Guess what! They dont work well unless grounded!! So...Im one to talk about grounds right?!! LOL!! Think I'll go test my theory since its sunny out. Good luck! Heres the diagram.

If it has an original "box" type VR either electromechanical or electronic then ground the 2nd male field terminal several inches to the alt case. If you have the '70 up flat VR then connect the 2nd male field terminal to the "pin" terminal in the right side of the VR "triangle" w it facing up like a pyramid as in Dave's pic

Unless Im missing something he said the car is running so why post a pic of the ign wiring.Use the first diagram for the charging system.I have no idea why everyone thinks when you upgrade to electronic ign you need to change alts.All you need is the old round back alt with the new style points replacement reg.My kids 62 300 runs it and has with full MSD and a big stereo and has for at least 12 years.My 65 is upgraded to the later reg and alt and I wired it like the first diagram.Been charging fine for 20 years.Rocky

You are correct, I was confused because my wiring was a clusterbomb.
In the end, I had it really close, I just need to add that wire off the last FLD connector.
BTW, here is one last question for you guys... On these alternators, are the two FLD connectors the same?

We ran the stock 62 alt for probally 10 years.It finally bit the dust so my son put my old 65 alt on it.Still charges great and he never has a problem.We both run underdrive March pulleys also.Some say that they wont charge or over heat but both run under 190 all day even in the 90s.I converted my 65 before they had the new style regs.My 65 basically need not much as it has nothing but lights to run.His runs a big stereo and amp.Rocky

Doesnt matter which field you use. They will interchange.
You're right rocks. All he needed was the charging diagram but since he posted a piece of an ignition diagram himself i figured id send a better represntation. I dont know if he has a factory svc manual or what his level of electrical knowledge is.
BTW Rocks... on charging system conversions ...that 62 you converted... did you upgrade the internals or is it still the old 35 amp guts? When I upgraded my 66 I went from single field to dual to get the advantage of 60amps vs the orig 35 or 46 and stayed with the mechanical regulator till it quit...then I ended up getting one with electronic guts that looked factory bcus mechanical ones are harder to find. Been thru 2 of those electronic fandagos already.
You are both correct. The reason I am so confused is because my current setup has the wiring with the blue wire (as seen in the picture here) connected to both the charging and the ignition wiring.
If this is setup wrong, then you can obviously understand my confusion. What do I do to correct it if it's wrong because if I add the lead from the splice as specified in the picture to the FLD on the alternator than the car doesn't start. I remove it and it fires up.

If you dont have a factory service manual get one.They are pretty cheap and worth their weight in silver.Id say gold but its too expensive now.LOL Rocky
