Arrived on site car was 100% non responsive. Hooked up the world tool and it was at rest on 1st floor both normals good and t1u was high t1d low so everything ok with where the car was. Fired a call to the second floor and the inputs for up,upa went high and wye for a second then delta and it showed it was in high for phase. Not a single relay picked on my mb board and the starters did nothing and it went into fault F after a min or so. We just replaced the mf io and the cps io boards a couple weeks ago. I’m at a loss I can’t believe I lost a board already. Any ideas are appreciated. Thanks in advance. It’s a 2 stop hydro. Powers good up to MB/p3-1 and rp is picked i swapped the relay for shits and gigs.
