BTW....I'm running 18V into the TIU channels. That shouldn't be a problem for the Tester when it's plugged into the OUTPUT channel....correct?
I’ll let others field this, but I think thats OK.
And all outputs should be disconnected from the track while testing one channel?
Yes. The transformer (in) and tester (out) are the only two things that should be connected.
