Lorne, so what I think we can say for sure is that the Horn relay is the center point for all circuit power to the fuse block. There are several connections on the two large tabs of the horn relay. Disconnect all connections except the one to the battery. Check for drain. Re-connect those connections one-at-a-time and see if the leakage occurs again.
Then follow it to the next point which is the fuse block. That fuse block has two pieces and if old and fragile. My 67 OEM was in bad shape with corroded terminals both inside the car and on the firewall side. If you break something, it will be hard to repair but you have to keep searching. The problem could be inside this clam shell fuse block. regards mike --- On Wed, 7/23/08, Peebles, Lorne (Services) <[EMAIL PROTECTED]> wrote: > From: Peebles, Lorne (Services) <[EMAIL PROTECTED]> > Subject: Re: [Chevelle-list] alternator charging > To: "The Chevelle Mailing List" <[email protected]> > Date: Wednesday, July 23, 2008, 10:33 AM > I had the wire harness opened up from battery over to horn > relay area > all the way across the rad support.
