I don't know, but I'm going to go back to the alternator shop today and have him take it apart and see.......If he can use one off the shelf and it works I will send the new one back.......

With all the issues I had with this swap and this simple issue (which should be a Non-Issue) ended up being the biggest and most time consuming problem...

Are you referring to the Holley alternator harness that is a single yellow wire? It’s just a simple 270 ohm resistor if it is. The other end should be connected to switched 12 volts. You can test the harness with an ohmmeter. It should read 270 ohms between the two ends of the yellow wire.

Finally figured it out.....Took the Alternator to the shop again along with the Holley harness ........ he used the Holley harness added 12 volt power to the harness......put the alternator to the test and Bingo 15 volts...Again he asked me how I had it wired up......told him keyed 12 volt power right into the harness...With the key on the connection check 12 volts into the harness.....So...He tells to check everything in the failed condition......Checked again (12 Volts) and started the car.....No charging so I check the voltage at the harness connection and it said "0" volts......ended up the wire I tied into had 12 volts power till the engine started then it dropped power......Don't know how or why......I changed to a different keyed power source and started the car and Bingo....15 volts.....everything is working perfectly now.......Sheesh !!!!!!!.... Drove the car about 50 miles and temp stayed at 185 and alternator charged perfectly......This Car stuff is hard sometimes........LOL

:thumbsup:

For future reference any pink wire will be ignition switched 12 volts.

I’m glad you were able to get it figured out. It always seems like the small things in the end that take the most time and give the most frustration.

I am wiring mine up following the info from Dirty Dingo https://www.dirtydingo.com/shop/mobi...path=4&pID=108

I bought a 4-wire harness and am using the C & D wires since I do not have a warning lamp. I also want it to sense the draw when my fans kick on.

How does your ride feel with the new setup?

Insane.......More than enough power for a street car.......Yet, keep your foot out of it and it rides and drives very good !!!!!!

Sweet!! Just how it should be! Very happy for you! :thumbsup:

Update.......No pictures but everything is finished......A/C charged and works perfectly.......Had a couple water leaks, all fixed.........then the car went for Tuning........Larry at ASSC did a great job.......he had some issues that he resolved getting the 4L70E trans computer and ECM to work together......The biggest issue we had is when driving the car normal everything is perfect.....But.....when he got the car on the Dyno, and put it under load.....the 2 small intercoolers (all I could fit in the space available) weren't enough to keep the AIT under control and the ECM pulled timing from the engine due to the water getting hot..........even with that the car made 544H.P. at the tires.....Since it's just going to be a street car I think it will be fine the way it is........my only other option is to put another intercooler under the car with a fan........
