I am running premix, previous owner disconnected vro system. I will try grounding the warning horn as well as the compression test this afternoon and I guess I'll proceed from there.
This may seem stupid, but every time I've compression tested I've done it cold, with water running and warm with water running just because the muffs we're going to be on there sooner or later...since I won't be running the motor for this test do I still need to hook it up to muffs?
