Message This is regarding the relay to my Snow Methanol system. When I run 15psi, I have the yellow wire off the relay disconnected from the positive terminal of the battery, and when running 18psi its reconnected. Last time it was connected for 18psi it was working fine, which was 3 weeks ago. Now when I go to reconnect it the pump doesn't turn on at my desired boost setting.
I then wired the pump's positive wire directly to the battery to rule out the pump being bad, turns out the pump is good.

My guess is the relay. Is there any way to test if this is the culprit?

Thanks
