Reply to "S Helper F7 ABA unit and cannot get it to run"

One suggestion is the the unit has a Dallee Locomatic card in it that will only respond to signals supplied by a Locomatic controller. S-Helper supplied many of their early F3 and some F7 units with the Locomatic option until DCC became more popular. You can open up the lead A unit to check to see if such a card is in it. If so, you have the option of removing the card and losing the sound (or installing a DCC card at some point) or getting a Locomatic controller from Dallee Electronics and controlling the motion, sound, and classification lights on an S-Helper F7 unit.

If the lead A unit does have Locomatic control and the other A unit and B unit do not, you will have to connect the B and trailing A units to the lead with the tiny MU electrical wires that S-Helper provided.
