The car is on the buffers trying to level up. Everything is coming on, LR and SVC outputs come on, but no UA output. LRU input is hot, US1 and US2 are made.125volts to the output board, can ground the UA output then the pump starts and the up slow valve is picked and the UA relay comes on. Only has 50psi at the valve but that's another issue. Safety string and the doors are made as well.
