I have a tac 20-03 that is giving me problems. It runs down on slow speed and it's momentarily pulling in vc3a and vc3b and dropping it. I don't have an ims CPU anymore so it's a little more tricky. It appears selector is doing everything as it should. All other relays seem to be doing the norm. It appears that it is constantly getting a down slow signal. All I have are a set of prints. Any help would be appreciated.
