Just pulled my alt off of my 85 and bolted it on. 3.5 at the plug. Started it up and it WORKS!!! 14.6 while running! So the Napa alternators that I got (all 3) only had 1.7v.

12.56 at both sides of the fuse when key is on and plug on the alternator is disconnected. 1.7 when plugged in.

12.56 at both sides of the fuse when key is on and plug on the alternator is disconnected. 1.7 when plugged in.

The readings that I posted were car running and hooked up. Tonight I’ll take the same with the car NOT running and I’ll try and find an 8 ohm resistor

The readings I took were with the car running and all hooked up, car all back together with all factory wiring

Car running. At Alternator 1.61 @white w/red, 11.93 @white At Battery. 12.14 At charge lamp, 11.62 going in and 1.62 out

12.17v going in at pin 5. 11.79 going into bulb, 1.58 on the other side of the bulb. All taken with the key ON. Car not running

Ok so I checked the white wire w/red from the alternator to the black plug under the dash to the fuse block, not broken and zero resistance. With the fuse out it’s 12 volts running. Put the fuse in and it drops to 1.7. I follow it from the other side of the fuse (tan w/blue) up to the plug on the cluster. The cluster seems to be stepping it way down. All my bulbs work. Is it stepped down at the Volt meter???

If I put 12v to both spades in the back of the Alt and it starts charging but it sounds like it’s working super hard. The battery is fully charged

Anybody have a cluster out of their 82 gl and can take some ohm readings for me?

Charge light work

My wiring is really good and nice still. Still had the ground wires and the first thing I did was clean all the connections. I’m trying to track the wire from the alternator to the fuse under the dash then where it goes after that. I have 12 at it with the fuse out then it drops to 1.7 when the fuse is installed.

I think I’m getting closer. The two pin plug on the back of the Alt has 12v at the white and 1.7 at the white w/red. Shouldn’t they both be 12v when the car is running???

Had the alt tested and watched them test it. 15.4v. Ugh! Ran a wire from the alt to the battery, another from the exciter wire to the battery. Two more for the coil and fuel pump. Then I jumped the starter to fire it up. STILL not charging.

Other than the fusible links on the pass fender is there any others that I don’t know about??
