DO NOT run it anymore (not even 10 seconds) till you swap the reg. I'm assuming you have an OE type electromechanical type reg? Your parts house has a Wells VR 706 (iirc) electronic replacemnt reg (does not look identical to OE) and mrrandyj at aol dot com has an electronic version with an black cover that does look identical to the OE electromechanical ones for $29 to your door. Reportedly you can swap your current cover to an electronic parts house replacement reg but I ain't sure which one that is.

Without further testing, I wouldn't assume the problem is the regulator. A high current draw or direct short somewhere in the system will cause a perfectly good alternator and regulator to charge at the max rate.

What further testing do you suggest John?
Do those voltage readings at the VR and alternator at idle indicative of charging at the max rate?

Don't be surprised if you have a bad connection at either the bulkhead connector or the connector on the steering column. Look at the heavy red wire at both connections. Look for discoloration of the plastic. Pull them apart if possible and check them. I had the same problem on my 71 Challenger and I changed everything out. Regulators, alternators, had it to two different shops, nothing. I was under the dash one day just looking around and saw a brown streak in the connection for the steering column to the main harness. I bypassed the connector and that took care of the overcharging problem. Remember, these connectors are 45 alomost 50 yrs. old.

I checked the voltage at the battery before starting it was about 12.75V . While idling the battery voltage was 17.50 - 17.62 volts ( seems high to me ) .
I checked the voltage at the regulator at idle and it was 6.8-7.5 volts. I checked the alternator at idle and it was about 7.8- 8.2 volts
Double check your readings.
It is impossible to have 17.5 at the battery with 7.8-8.2 at the alternator.

Those are blue wire ign1 field terminal readings as opposed to a alt batt stud reading and they are low cuz they were taken at idle (alt ain't puttin out) whereas at a higher RPM the field terminal (blue wire circuit) voltage readings would be in the 17+ range (as would the entire electrical system) from the alt putting out what it is capable of & the bad (full fielded) reg telling/allowing it to put out all it can.
Ok he didn't specify that, but if so, 1. he is losing 1V between the alt and reg. 2.The ign side of the reg should be close to battery V or 17V,
You say the readings are low because the alt is at idle and not putting out yet his battery V is 17+ ????

Oh OK I see what you are sayin cuz he does state that his batt voltage is 17+ at (normal/slow?) idle

Never had a weather related problem with my points type regulators that I recall. But the farthest north I ever was running this system during the winter was Memphis in 90-91. Yeah, it snowed there.
They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.
