Im running ms3 pro, im running my 2 step wire to ground side of relay as well as to a grounded momentary button that grounds relay, then have relay constant and 12v switch ran to a key on toggle switch and power going out to my t brake from relay, brake is grounded to case. If my relay is not powered the 2 step rpm stays activated, anyone know why?

Why does 2 step stay on when relay has no power

Re: Why does 2 step stay on when relay has no power
Should relay be setup to just trigger ground? I want to figure this out because i plan to run my nitrous off ms3 pro and dont want it spraying nitrous when its off

Re: Why does 2 step stay on when relay has no power
all of the switched inputs except one are meant to be ground switched to activate

Re: Why does 2 step stay on when relay has no power
Can you draw on a PC of paper how this is wired and post it?
As noted, ground inputs. My pro is wired with wire ground then to trans brake switch, from switch it can go to the relay and T off to pro for two step input. Mine is wired from switch to pro only and I'm using an output to trigger the ground side of my relay for bump box and delay setups
