other clues/hints as to where/what to look for regarding the surging
CC when ever the turn signals are activated? TIA.
Still say ground. However since the CC actuator in this
car is a servomotor, and that requires significant current
in order to be able to yank on the throttle, my money is
on
Does it surge when both sides are on or just one side?
I would check the taillamp chassis grounds, since the CC does pass current
through the stop lamp bulbs; a weak ground will allow current from turn signals
to backfeed quite easily.

I think this is why bad grounds are such devilish problems. The
continuity can look OK under the tiny current of a test meter, but under
actual loads you get current seeking ground in various other paths.
The usual advice is to take apart the ground connections, clean with
sandpaper or wire brush
See if it surges when you flick the headlights on and off.

Since a couple of ya' suggested that the surging CC in my '85 300TD is possibly
due to a bad ground, I checked the continuity of the brown ground wire in the
wiring harness which goes to the CC and also checked continuity to the
pertinent soldered pin on the CC PC board and continuity looks goo
Bad ground somewhere.

Grounds are dirty, or the alternator is weak. Those are my guesses.

After obtaining a '85 300TD from my brother last fall and the CC wasn't
working, I opened it up, resoldered the PC board, and got it working but hadn't
taken any trips until last week to notice this oddity. The darn thin surges
when the turn signals are in operation. Anybody got a clue? TIA.
