It’s done. A little more residual pressure in the pump than I anticipated. However the oil was indeed low. i topped it up and the pump is quiet and it blows cooler than when I started. I certainly appreciate your help. Thanks for your time!

Thanks for the reply and assurance that I won’t lose my full charge. I am a little confused about the steps as when the oil plug/bolt is removed it will immediately purge the pump. Your steps say to purge after checking the oil level. I don’t see how that is possible unless I didn’t comprehend...
Hello all,
I finally got around to charging the AC on my sons 72 mustang. All went well initially, but after I shut it down and let it sit for an hr the compressor is making a grumbling sound.
I added oil initially before charging the system and it was at a level of 1”
After charging it was...
Just a bit of a follow up. My son and I are finally driving this car. 1-4th gear it does ok, but 5th is a straight dog. Anything under 70mph and It is gutless. I installed a 3:40 which I assume is out of a MustangII it was $50 so I figured why not. It certainly did’t help much. so now I am at a...
So….. Ta Da! It’s fixed. Turned out to be a cut green/red wire in the headlight harness directly under the radiator along the crossmember. I would like to thank each and every one of you for chiming in and offering advice. Your help was definitely needed.
I am attaching a picture of my...
I haven’t mentioned it because I assumed it was only one side of the idiot light and is a non player. Also it wasn’t mentioned as being that important Apart from naking the alt light illuminate. It does exist and is connected correctly. The diode that’s inline could be toast and I need to...
Frame ground and ground for the regulator reads 0 Ohms. Measured from negative battery terminal to frame and to regulator case. I have constant 12V on the yellow wire on connector C4 ( A terminal)
F terminal which is orange/ light blue is the field wire and does not have 12V on it key on or...
Ok with taking everyones suggestions, verifying and Ohming wiring, replacing alternator( it was bad out of the box) replacing regulator I still don’t have a charge. Now, one thing that I am thinking is the ignition switch is out of a ‘73. There are 2 different part numbers for 71/72 and 73...
At this point I am really at a loss. I appreciate all the advice guys! I have to work away from home this week so I will revisit the issue when I get back. I have the warning lamp. Full gauge package to include tach is down the road. I will have to do it all over again when I do.
I already mentioned they were wrong in the photo….
the “somebody” was me because I was trying to match the factory diagram. Like I said, in the wrong configuration (as shown) it charges. If I do it the correct way it does not charge. Rest assured it’s correct now.
If you are wondering what...
Thanks for the reply and troubleshooting suggestion, good idea.
I am attaching a picture of the way my C4 is currently wired. Alternator is new and as of yesterday a new regulator is installed. The photo shows my green red and yellow they way they were when charging and they are now swapped.
So, things are not as well as hoped. I am still having charging issues. If I run my wiring as layed out in the factory schematic found here it charges however, it also drains the battery overnight. the confusion is related to the yellow white and the green red on Connector C4 to the regulator. I...
Hello all, My son and I are finally driving the 72 Coupe! Everything seems to be working well apart from my charging. I am looking for a little sanity check to verify if I have the regulator connector wired properly my schematic does not have the F S A I on the regulator diagram so I went left...
