BRILLIANT! You, Freyguy are a gentleman and a scholar. my U7 is on an IC socket and is therefore much easier to remove. I indeed have +12 on pin 1 and when I remove U7 and power up, I have +12 at pin 2. Furthermore, the signal at pin 2 looks like a PWM signal ... drops to 0V DC more and more as the throttle is applied. So, it looks like U7 is the culprit.

New one is on order.
Got my fingers crossed - I'll update once it is replaced.

Thanks again,
Michael
