green means good
Great for my toro z4220. I Liked how the light was light when it had power. Easy to tell when it quit.

Fit on my Case 70XT skid steer…. It’s handy having the light on the relay so you know if it’s working or not!

Didn’t make a difference
Maybe I got a faulty one. But I just thought it really didn’t work, checked the ground and everything was still getting power but got nothing from this. I returned it with no problems.
