Thanks For the info guys!
Here is what I have so far... I downloaded the manuals for my Fluke on the internet, ( It was purchased on Ebay, no manuals included). Just as I thought., It does measure duty cycle!! Here are the results from my examination:

Duty cycle with ignition at position 2, engine not running= 69.4%

Duty cycle while engine running pre operating temp. = 51.2%

Final duty cycle above 80C operating temp. = 18.1%

I attempted to adjust the idle adjustment screw but the duty cycle stayed the same the whole time!!! Yes, I did make sure I depressed the adjustment screw so that it was enguaged. I also waited the 10 seconds for the reading to correct itself......

Any suggestions??

Thanks for your help!!
