I'm upgrading my fleet from Lionchief Plus to Legacy, and looking forward to getting my 990 Control System up and running! My layout consists of Atlas O 3-rail track. The 990 instruction manual states that I should connect the Command Base/Charger binding post to BOTH outside rails. Some online videos claim connecting to only ONE outside rail is sufficient.
Any thoughts/advice from the Forum on this for a novice Legacy operator..?
