I think I have a bad starter relay/solenoid? The relay has 4 posts, 2 big and 2 small. I know one comes from the battery and the other goes to the starter. One of the smaller ones is a ground and the other not sure. I want to test to see if it is even good using my ohm meter. I took the relay off of my ski and want to know if I just test it by hooking up one (+) and one (-) lead from my ohm meter to each of the small posts only? How do I test my relay to know if it has continuity or if it is good or bad? Also, how do I correctly install the relay on my ski. Again I know what the posts are, but does it matter how I hook up the smaller posts? Thanks
