There are 2 resistors in series with the blower motor fan on a Non A/C car and three in an A/C car. They are used to control the speed of the fan, low and medium speeds. The fan is directly connected in high speed.
How did you hook up the alternator output to the battery? Sounds like you directly connected it from the alternator to the (+) terminal. The stock ammeter measures current flow through the charging wire connected between the (+) terminal of the battery and the main power distribution terminal on the horn relay. The stock alternator connects to this point on the horn relay as well. If the alternator output is connected anywhere else you will always measure a discharge condition on the meter it will be most noticable with the lights on or the fan in high speed.
