hi, i am after a basic type schematic to controll the speed of a 12 volt
dc automotive cabin fan .

seems to be a bit of a problem in these saab`s.

any schematic using a mj11032 or mj11016 darlington would be good. if
not any electronic speed controll schematic will be fine.
the original darlington is rated at about 25 amp , seems a bit excessive....
these darlingtons i have are rated at 30 and 50 amp.

thanks, mark k
