My TIU signal on a few pieces of new, cleaned gargraves was 9-10 on all channels. Whew. But I do have a USB scope and a laptop, I suppose I could get my geek on and look at signals.
Now, am I correct in my reading of this thread that the PSX-AC boards damage the TIU to eventual failure by virtual of doing their job (surge protection)? IE the more derails, fat fingered car handling you have, the more it damages the TIU? Is it only when the TIU is used passively? Or both active and passive setups? I have 4 major power blocks, and PSX-AC boards between my Z400s and the track. I like that they kill power when there's a short, but restore it when the short is fixed. Very handy for operating. But I don't wanna kill my TIU. And I'd rather not open the dang thing up and do surgery...
Sorry if this is already asked and answered...
