OMG! I never got any notification of your excellent posts, Patrick. So I apologize if I appeared to be a jerk and not at least thank you for your thoughts. OK....

The Kirkham wiring diagram is on the 'net and I tried to download it into a pdf, which is attached.

1) The alternator I put in is a rebuild from O’Reilly, the voltage regulator a BWD, from O’Reilly, part number R400 (4wire). (Both for a '65 Ford Galaxy 500 XL) The old VR was a "2 KD ??7768" or something I can't recall off hand, tho' it's at home on the work bench.

The alternator now charges fine, according to the voltmeter and the ignition light on the dash behaves correctly. However, the problem is that the VR seems hot to the touch, even if the car has been sitting for hours.

1A) Even with engine off, and key off, the “field” terminal on both the alternator and VR are “hot”. Is this correct?? There is def’n current flowing between the alternator and the VR with the key off.

2) The car has two sets of fans, independent of each other and on separate circuits. Both fans operate manually with their own toggle switches. There is no sensor anywhere.

2A) The little, twin, front “pusher” fans are fine. No problems. Both fans run from the battery....the key can be in your pocket, engine off, and they will run.

2B) The big “sucker” fan operates with a relay and a toggle switch under the dash. It don't work now. I think the problem is the relay or maybe the toggle switch. Not sure if this is related to the foolin' around I did with the voltage regulators and alternators.

thanx steve
