The new harness and voltage regulator resolved the charging issues. Next up was swapping out the failed turn signal assembly. Man, these old cars are so easy to work on. It took longer to clean up the column parts than it did to actually install the new parts. Another item checked off as both directions work as they should.

The truck also has a very old under dash switch that had me puzzled originally. But I noticed it was wired in series with the turn signal wiring and turns out to be an emergency flasher. It looks like it was a GM accessory part as it has a bowtie on the knob that lights up/flashes. And with a new flashing unit installed, it also works.

Next up is a stuck fuel gauge (stuck just below 1/4 tank). Based on what I read, this is probably a sunken float. But I am going to do some other tests tonight to confirm the wiring is good.
