Hello, all! Trying to find a copy of the charging system wiring diagram for my 66 Ford T-Bird. Anyone have and willing to help??
I'm driving myself insane trying to figure out what the prob is.......have put in now two new alternators, thought the first was bad from the box but now am wondering if something is causing them to burn up, also replaced the voltage regulator and have now completed ALOT of rewiring to clean the mess up. She was a Christmas gift from my wife two years ago, and I am now starting to tackle the challenge along with my 9 yr old son.....supposed to be fun however it is starting to be hugely frustrating! ANy help is GREATLY appreciated! Here is a link to an online photo gallery of the car...... in case you are interested! LOL!

I dug these up for a 67, don't have anything for a 66.

Give me some time, I'll scan in a page from my 66 T-Bird Shop manual. The are reproduced, all of the T-Bird Restoration parts houses carry them, around $30-$40 and they have the diagrams in them. The electrical assembly manuals do to.

Jwko's diagrams are pretty much the same as my 66 ones, but I'll post mine for reference, and a couple others.

Here's a diagram of the alternator wiring connections.

Here's the full starting, charging, and ignition circuits, the second picture including the wire color key, which was not in jwko's diagram.
