300SD power antenna won't stop running...

When I went to lunch the other day, I noticed my antenna motor was running down the battery when I got in. I could hear it running before I got in.

I took the cover off today and played with it. The antenna goes up and down ok, but the motor never stops running until I play with this little black cog and copper prong thing.

Right now I just left the antenna up and unplugged it.

Any idea if that cog is replaceable or should I be looking at other parts on the inside?

I will try to get pictures of it posted.

It's either the shutoff built into the motor or your antenna switch is stuck.

I am certain it has to do with whatever shuts it off. It seems the little black plastic cog might be a little worn and I guess I will play with it some more.

As soon I get a chance I'll post a picture.

Here is a picture...

I don't I don't know how to draw arrows and things on pictures...but what I have figured out is that by playing with the little copper "thing" that is on the black cog above the big wheel it will turn off the motor. I think it is out of alignment.

Is there a rebuild kit for this thing?
