guys, I need to make a fan speed controller for my condenser.
improvized kasi yung aircon radiator, it is bigger and it has two huge fans. the aircon was really cold, but later I realized the alternator could not take the load on idle thus killing the battery sooner... (increasing idle is not good enough)

adjustable, or permanent medium or even low speed ok lang sa akin.

I am thinking of buying this resistor?



can I hook on them directly? or are there any better and more convenient part that I could just salpak "series" them and go...?
