Horn and ammeter problems
Hi,
I'm new here, but not to Corvettes. I bought my first one new in June of 1967. It was a Sunfire Yellow 350HP four speed coupe witb leather, power brakes, and tinted glass. I sold it two years later to exercise a stock option in the company I was working for, which netted me nothing. In 1987, I realized the error of my ways and bought a good original Goodwood Green '67 coupe with a 350 HP four speed, power steering, a vinyl interior, and power windows. At the advanced age of 65, I now think that Goodwood Green is a better color for a coupe than the yellow.
Anyway, when I bought the car in '87, I went to the local Chevrolet dealership and bought every new part I could find. This is the root of my current problem. I started a restoration on the car a couple of years ago. Being a "long-time" owner, I thought I knew more than I did, and wasn't quite careful enough when I took it apart.
My current problem involves the horn relay. The horns don't work (they will work if I "hot-wire" them) and neither does the ammeter. After looking at the wiring diagrams, I came to the conclusion that these problems were probably related. I have been messing with this for two weeks and am getting nowhere, so I thought I'd try here. Here are my problems. The horn relay I bought in '87 is part number 1115889; according to the AIM and the '67 judging manual, it should be 1115837. So much for Chevrolet having the correct parts in 1987. I did some searching on this forum, and it appears the original relay should have 2 screw terminal and 2 spade terminals. The later part has 3 spade terminals. Is the later relay a functional replacement for the 114837? If so, which of the spade terminals do you use? Also, the wiring diagrams show a 20 G Orange wire (fusible link) connected to a 16 GA Black and White wire that goes to the Ammeter. I have looked for the life of me, and can't find a trace of that wire, or any sign it was removed. The car has it's original wiring harness, and besides being a little brittle, everything else works fine; it doesn't appear to be butchered at all. You may not believe this, but I don't remember if the ammeter ever worked over the last 20 years, the needle was always around the middle, and the battery never went down. I am a bit hesitant in unwrapping the wiring harness to look for the missing wire, but if somone can assure me it's there, I'll look for it. In searching the threads, I see that some other folks had their relays mounted upside-down (cannister down). I had mine in that way because I thought it was right. The car starts, runs and charges fine, so I have to believe there is something simple wrong, but for the life of me, I can't find it. Any help will be appreciated. By the way, this is a March built car.
