Hi guys, I installed a 4-pin, 40A relay to make the starter work, but it sounds like it's only activating the gear but it's not turning.

Maybe I connected something wrong?

I connected it the same way as in the picture.

So I have to do some grinding on the metal in the red circle, and about a foot away is the engine, in the blue circle. The engine is coated in grease and oil from a leak, is it a fire hazard to use a grinder so close, and if so, what can I do to block it off?

Thanks.
