"Pulsing" voltage, RPM drop with load.

lighter not switched in 67 at least
Thanks! I was wondering about that. I thought it wasn't, but then recently was working on something that was..

edit: yes and should be a red wire in '67. My car was a little hacked with an aftermarket a/c probably done in the 60s, and then what I did in 80s. Hope to clean it up this year.
Just checked a '73 Dodge FSM and cigar lighter is not switched then either. I'll correct my post. Thanks.
