Hi 1sweetride,
Thanks for the information. I wasn't able to try it this weekend, but I was able to find some comparable resistors to use (50 and 20 ohms, 1/4 watt). I was working on fixing my HVAC controller - replacing the potentiometer and modifying the case. Good luck with your troubleshooting.
Sincerely
-Jerry
PS. I noticed you mentioned you have/had a 68 mustang. I have a 67 mustang that I'm replacing the old points ignition with a solid state add on from C.J. Mustangs.
