cooling fan problems
heya i've had this 93 escort for over a year and the cooling fan has never worked as long as i've had it. basically, i didn't want to deal with it so i hooked up a light switch which sits in my cup holder. recently i've had charging issues and i would really just like the electrical system to be in its virgin state. along with the charging problems (FTR: on an alternator that tested at 15.5v when removed from the car opposed to 13 when installed) my temp gauge reads innaccurately. sometimes it's 3/4 of an inch past the "H". i'm sure this is due to a fautly sending unit. i guess my question is what the hell switches the fan on? does the sending unit go to the gauge and then from the gauge to the relay or whatever switches the fan on? because there's just 1 wire that comes from the sending unit.
