Check and clean the terminals at the threaded junction post on the horn relay. I've had this problem before and cleaning those terminals helped a lot.

If the alternator plug terminals are "l l" then its externally regulated. If it has "- -" terminals then its internally regulated.

All 1970 442s came with internally regulated alternators.

Is the new one open face like the factory original?, or just a generic rebuild.

I hope you kept the old one and didn't turn it in as a core.

Because when people are looking for/at W cars, they like them to have all the original parts. All parts removed from your car are valuable.
