Ok, first thing, I'm no mechanic.
2004 SS800, has had some starting issues lately. Sometimes it works fine, other days she's not happy. Turn the key, lights come on, the tach and speedo go up the dial and back. Hit the ignition....CLICK!
I figured out one day, that by turning the battery on its side, it cranks up. Weird.

I took the battery to a shop, they said it's ok. I tried to jump it with my truck, no go. Then (probably not a good idea) I removed the battery attached the jumper cables directly to the wires themselves, and still no go. So that says to me, its not the battery at all, yes?

I traced out the wires to the starter ( I think). It's a little black box, kinda round). This is the thing that clicks apparently. Ideas, anyone?
