generic tempstar furnace

my air cond wont blow. no output from 24v transformer. replaced transformer and still had the same problem. metered the input had 120 between black and white but still nothing from 24v side. if i connect the black primary and then ground the white to simulate a neutral i can get the outside unit to go but no blower. the neutral returns to a relay thru a jumper board. do i have an internal neutral problem, blower motor problem or is the relay associated with the problem?

What about the contactor in the outside unit. If you push on it, does it fire up, when there is a call for a/c? Also, the capacitor can go bad, is that bulging? It looks like a soda can.

neutrals NEVER go thru a relay. post a pic of the wiring or look at the original wiring diagram on the back of one of the doors and wire it back to original specs.
