It's been a while since I've posted here, but I'm sure the advice is as good as when I used to check in more often. I've been trying to locate the cause of my battery draining. I'll drive the car one day and by the next morning the battery is completely dead. I just replaced my horn relay, and discovered that when I hooked the battery back up, the new horn relay makes a clicking sound as soon as it's energized. One of the wire terminals on the relay had been hot enough to melt the plastic around it as well. There's still a spark at the battery terminal when the battery cable makes contact, so I know the problem isn't fixed. I was just wondering if anyone had an idea where to look next, given this info. Do you think there could be a short in the horn wiring in the column? Oh yeah. The car is a 67 vert, automatic, originally 326 but now it has a 400.
