Still trying to find my power loss issue with my charging system. I did a voltage drop test from both the ground to battery and battery to starter solenoid and it was showing .172 and .151 respectively. I read in Carcraft that this is acceptable (between .1 and .2 is ok). I'm reading a very high 16.2 volts coming off the alternator but a low 12.2 at the battery which is a BIG loss. My only other though was broken wire somewhere seeing as the battery, alternator and voltage regulator all checked out. So where do the wires that go into the voltage regulator go to though? I know 'F' goes to Field on the alternator, that has continuity. I know 'A' goes to the starter solenoid and that has continuity as well. I think 'S' goes to the ignition switch (black/green wire correct?) but where does 'I' go to? My wiring diagram only shows 3 wires coming out of the voltage regulator and a 4th that is the radio suppression condensor. Any help would be greatly appreciated!

I believe 'I' comes from a split AFTER the resistor wire which comes from the ignition key.

I believe someone around here has a nice pic of wiring schematics. I'll try to track them down and link them.

What does 'I' plug into though? Like a spot anyways where I can test for continuity. If the schematic you are referring to is the one that shows up with the small pics on the left side of the page that you can click on I own the book that they scanned those from. That's what I'm using that is only showing 3 wires off the voltage regulator. I have a factory wiring manual I'm going through right now however so hopefully that will help.

Isnt I a post on the solenoid (smaller pair of posts on the RH side as you view it from the engine side, usually it is labeled I and the other smaller post S), on a 67 it takes the brown wire. The S post on the solenoid takes the red/(I think blue stripe) wire, I only looked at it two days ago.

(revised)

67 Shows 3 wires off the plug on the regulator. One is the 904 green/red stripe wire that had me plagued. It is from the ignition switch and signals the regulator to work. There is also a ground (black/red-st) which attaches to the regulator body (at least on a 67). But then the other two, one heads to the solenoid (yellow) and the other to the alternator (white). (FYI: they are no longer on my car but I documented where they came from at one time).

66 Blue coupe that is the diagram I have in my hands right now. Link is also bookmarked, thanks though! Ok, I figured this out. The wiring i have in the car currently is not correct for it. It's off of a 65 with a generator even though I specifically asked the guy I picked it up from if it would work. The 'I' in 66 is not used. A is the yellow wire that runs to the starter solenoid. S is the green with red stripe wire that skunked spoke of and F is the white field wire that goes to the alternator. Thanks for the replies guys, I really do appreciate the help!

I thought you had switched topics to the starter solenoid, so I was stating where the I from the starter solenoid goes! DOH!

On my '66, the voltage reg. only has 3 connections, allthough the harness shows 4. I have 3 wires running from the regulator ( not counting the little noise supressor ), and they go to the ignition, constant hot, and I believe the third goes to the altenator.

If you don't find a solution to your particular setup, I'll check my books when I get home tonight.

I clicked the link given above, then changed 1966 to 1965 and there was info as well.

Does this page have the info?

Yep - looks like there are 2 wires going to the alt.


Here's a 64.5 Generator setup...

Thanks for the replies Coupe, we got it all straightened out. Had to refer to my buddies 65 wiring diagram to figure it all out. Thanks for all the replies!
