PeteVS Grease Monkey Registered: 12/15/10 Posts: 10 Loc: Morris County NJ	My brother and I are "harvesting" a '79 Caprice for the engine and whatever else is worth taking. It has a 3 wire alternator which must mean that there's a regulator lurking somewhere under the hood? Under the dash? We got the main light and engine harness out pretty much intact (except for cutting the wires running down to the starter.) All of the wires ran to the BIG plug next to the brake booster. It's a real rats nest under the dash, but I haven't found a regulator yet. Thanks for any help here! _________________________ Don't never get rid of nuthin!!!

Im suprised it wouldnt be built in, into the alternator. Your traditional regulator and generator system would have been "off the scene" WAY before '79. Atleast i would have thought. Again, i could be wrong Edited by OilSpot (07/15/11 07:39 PM) _________________________ In my shop, quality is a standard, NOT and option.
