problems with FAV solenoid - no work, but getting very hot! ::fixed::

[softic]

oooh... Richard, I am very sorry - I was typing my replies from Blackberry mobile and mistyped the voltage!
The voltage on PIN 1 is 0.1V on idle and from 0.5V to 1.4V on throttle after threshold is reached (I lowered down the threshold for more easy testing).

So there is NO 12V, but 1.4V maximum... sorry for this misleading typo
What to do in this case?

Do I get it right, that you use PIN 1 as transistor opening control voltage?
Or it is something else?
