Hi, Kyle,
I tend to agree with Dave -- every symptom you've identified with your Herbie
could be attributed to low voltage. So there is something in the system
causing a voltage drop (duh).
The aggregate of too much resistance in every oxidized terminal or loose
connector is the usual area of first attack. And since so many different
functions are being affected in Herbie, I would quickly get very suspicious of
the system ground. (I work on ambulances and police cars, which are notorious
for having a lot of added-on current-suckers. Ground problems account for
about 60% of the electrical problems I solve.)
Each component needs to be well grounded, obviously. Wiper motors, flasher
relays, lighting, horn -- especially if your car was repainted, be sure there's
a toothed washer at every attachment point requiring a chassis ground. And of
course: be sure any ground terminals (you'll recognize them by the brown wires
running to them) are paint-free. The turn signals atop the fenders must be
mounted with toothed grounding washers on their undersides.
Look at the main battery ground cable. Clean up its battery connection. Look
where it's attached to the chassis: clean and paint-free? Have a good toothed
washer there? Cable shoe polished clean? Any acid ever gotten wicked up into
the cable? Is it original naked flat braid or PVC-jacketed cable? If there's
any discoloration, replace it. If it's a vinyl-jacketed cable, replace it
anyhow. It's a cheap intervention that can work miracles.
Happy hunting. The grounding is just one area lots of us sleuths fail to
attend to very much, but it affects the entire car.

Wants to really go in first and second.
Wipers died in the down position. Was jerky and sporadic before dying.
Turn signals no longer blink quickly, just stay lit (indicator only, not actual
signals.)
He's a 66 standard.
Converted to twelve volts.
75 amp alternator
1600 dp engine.
single barrel carb, 30 pict series.
his battery did run down the other day.
Let me know,
Kyle
