ok went back to job and checked selector/magnet alignment and swapped all relays that could have been part of this problem. basically just tried to move the problem as i didn't have any of those type relays with me. however problem continued. I remembered that at some point i should lose the voltage on ntsb as it fires low. As it turns out i was never firing ntsb. i jumped it out and it worked. high speed was back so i took jumper off and its still working. my guess is something has moved very slightly and a new terminal back up scan is in order. without a cpu w/ ims and possibly an adj. manual I'm still flying blind. i am contacting liftwares tomorrow re ims
