    Pin ohms at 200k going from gnd read 46.9 next 34.8 and last 42.4 now you will
    know if it is a good resistor.

    old resistor, pin next to gnd read 7.3 , fan didn't run at start up, put in new
    resistor and fan ran so it looks like I can put car back together. cost $24.00

    I'll add to take most readings like that with a grain of salt, just because the thing is not, in fact, a resistor. It's a solid-state, pulse-modulating motor controller, and when you try to take "resistance" readings of something like that, what you get depends a lot on what your resistance meter does when hooked to something that ain't a resistor.
