I would definitely check the exciter wire at the splice near the RF
headlight. On both of my T44s, I replaced this with a solid weatherprof
crimp. Also measure voltage on the alternator ans starter posts. One of my
cars had a large drop across these cables and I ended up replacing the one
from the alternator to the starter. Cleaning the terminal connections may

I presume that means the regulator ain't regulating properly, but the dreaded wiring "weld" in the passenger footwell is passing on its voltage without any resistance.
