Comfort Control working as it should

[Christian Doerk]

Hi friends,

after checking all the functions of my Comfort Control of my 1964 Fleetwood, everything is working as it should. The control of the temperature is working really well, except one thing... 

When the car is in idle on a traffic light or driving very slowly, the voltage of the alternator drops about 1.5 volts and the transducer does its job correctly and is switching to warm. On a hot summer day this is not very funny. I always have to shut off the A/C. If I raise the idle a little bit, the voltage regulator raises the voltage from the alternator again and it's switching to temperature, set before. This is the normal behavior, isn't it?
What I currently still couldn't find out if anyone else has the same issue. Shouldn't be there are voltage regulator in front or in the Comfort Control Amplifier to make sure you always have the same voltage?

Or probably the original voltage regulators always charged the battery when the engine was running? Don't think so, right?

I now will put in an additional 12V, 20A voltage regulator directly in front of the amplifier to make sure the voltage never drops and will always be stable at exactly 12 volts.

I'll keep you up to date.

Mr. Doerk, 

Your question is beyond my level of expertise and I am not near my manual.  I write only to suggest or ask if the hot idle compensator for your carburetor is functioning?  I believe it should raise the idle speed when the car is at a stop so as to avoid this type of issue.  Vacuum leaks are also perennial candidates for causing similar issues and there’s no shortage of areas in which they can occur.  

Wish I had more insight to offer but hope this helps to either to fix the problem or eliminate a one or two possibilities.
