Melted Voltage Regulator on '93 Supersprint - Anyone know wiring well?

[Tony]

Good morning,

 

Noticed a trail of sticky material under my alternator which migrated inside the alternator.

Required professional help to clean out the alt and replace the voltage regulator.

 

The tech said that if the small lead (Brown/Yellow) next to the two large leads was grounded, it would cause the reg. to overheat.

Sure enough, it shows about 54 Ohms.

That lead goes directly to Ignition warning light, Tach, Oil Pressure light, Water temp guage, heater switch, rear fog switch, on and on and on......

Seems to me that any number of those connections might be grounded on purpose.

 

Anyone have any experience with such situations?

I am not interested in going through the harness looking for grounded spots!

 

Really hope someone can help.

Been driving it like that for years until I noticed the mess.

Carbs back on, alternator replaced, ready to go. Except for concerns about wiring I'm ready to connect the battery and hope for the best. One more question though. With all lights off, key off, no other things on that I'm aware of, Should there be any voltage measured between ground cable and negative post? Even with all alternator leads disconnected I'm getting 12.68v. Would there be anything on all of the time?
