If the ammeter is discharging then not, somethings pulsing, like the turn signal. With key off the charging system is cut off, so when it's on, it's pulling current//discahrging. Apparently a short other corrosion related issue might be there or faulty signal flasher. Check the dial frequency and see if it's about the turn signal time span. If not, it's something else.
I'm not a fan of screwing around with old wiring. The diagrams are on here, it's not that big a job to rewire the critical stuff, at least you know it'll work.
Test the horns first. Pull the lead wire off and hot jump each one. If they growl, they're probably OK, just clean them up. If no sound, they're shot. Good place for critters to hide stuff or water to sit. Then work back to the relay. The horn relays are readily available so I wouldn't screw around if it's rusty. I'll donate the one I'm not going to need, if necessary.
