So I bought an '87 FC GXL a while back, and I've been working on getting it drivable. It does drive now, but the "add coolant" buzzer was going off, and the light on the dash was on. I sorted that out a mouse chewed the wire. The light on the dash is gone, and the buzzer has changed. It was very annoying before, but now it's pretty polite, not nearly as loud, and there are no lights on the dashboard. I was wondering what would be a good place to start looking.
