Wire Connections - Alternator Harness at Fender Apron
#1
OK, I am enjoying the benefits of getting older and forgetting things, So I need some help here.

In the attached picture I show a post and a ring terminal on a wire. From my alternator there are three wires that are wrapped in a harness that go over to the fender well. The orange and the yellow go to the voltage regulator connection, and the black one with the ring terminal goes.............

In the picture. I believe I removed it from the junction block to the front side of the solenoid. Is that correct? I cant read the wire diagrams or assembly guides well enough to answer this question.

There are two configurations: one for a tach dash and one without.

For the standard (non-tach), the battery cable, fusible link ring connector, and the alternator cable all go to the starter solenoid.

For the tach configuration, the battery cable and the fusible link ring connector go the starter solenoid; the headlight large cable (black/red) and alternator cable both go to the isolation post to the side of the starter solenoid.

Sorry, I am a Mechanical guy, not electrical.

So mine was born a non-tach car with the 65 amp alternator, 3-guage center stack, rear defog, and NO TACH!

I had you add the Tach connector to the harness. So now I am a tach car.

So, what is large black wire from the alternator called? Is that the alternator cable?

What is the isolation post? is that the "junction block" I pointed to?

Thanks!

Ahhh...the 71 standard dash with 3 gauge cluster is the odd-ball exception to the rule, and it follows the tach-dash configuration. The wiring changes are not driven by the tachometer; rather, the tachometer replaces the ammeter with an alternator indicator lamp. The lamp versus the ammeter determines which configuration to use.

And yes, the isolation post is the junction box you're pointing to. The big wire from the alternator is the big wire from the alternator. *G* It feeds the battery from the alternator.

OK, so the large black wire from the alternator goes to the isolation post, then I have no fires, right?

The last thing to connect then will be the starter, which I have a new "high Torque" starter with 2 cables. On this starter I believe the large black wire goes to the battery side of the solenoid, and the smaller red wire goes to the switched side of the solenoid.

Can you confirm?

Thanks!

I don't know absolutely sure 'bout the new-fangled starters' wiring, but I think that is correct.
