I have an atv spot sprayer I got about 4 years ago. It has nor seen
alot of use. My dad was using it and he said it quit spraying. I looked
at it. When you put 12 volts to it it might turn an 1/8 inch and
releases when voltage is removed.

I took the cover off. There are two magnets on the end. Two springs
came out of it. I dont know where these springs go. Now it wont move at
all.

How can I tell what is wrong with it?
