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
