My irf610 just completes the circuit regardless of the gate signal. My LED indicated if it's flashing at the frequency of the gate signal. The gate signal is about 10 volts peak to peak AC square wave. I have tried off setting the gate signal so that it would be DC pulse but still nothing. I thought maybe I burned my mosfet so i tried a brand new one, still didn't work. My signal is coming from a function generator and its negative terminal is grounded to the power supply's ground which is grounded to the wall outlet.
my switch is wired with the simplest setup possible:

My power supply is 24 volts and i have 110 ohm resistance so it should be giving approximately 20mA current.
It worked 3 weeks ago. I have no idea why it's not working now. I've been at this for 2 hours. It's very frustrating because I am trying to get this done so I can move forward with the circuit I am suppose to turn on and off.
Please don't give me a long pdf of everything about transistors I am only wondering in simple terms what the problem is.
Thanks.
