@gunrunnerjohn posted:If you have an 18.6 volt input with no load, then to get max voltage, just crank the remote up to 22V. It's in Barry's book, but it's a fairly long explanation as I recall. Sometimes there's so much detail in his book that it's hard to find a simple fact.
John, wanted to circle back and thank you. I'd have been pulling my hair out wondering why I was seemingly experiencing voltage drop inside the TIU.
Cranked her up to 22V and got 18.5V on the tracks to match the 18.5V at the output terminals of the transformers. I checked every piece of track and was spot on except one which looked like it had bad/loose connections. I fixed 'em and now they're all up to 18.5V.
