Howdy!
I have a PS2 Premier ABA E-8 that confounds me. The lead A unit runs fine and the tether to the B unit and REAR A unit is good. The problem is that the REAR A unit isn't running in FORWARD. It will run in reverse no problem. Could this possibly be a battery issue?
Thanks .... Mark

Mark,
It's not a battery issue. When the rear A unit is on the track alone and not connected to the lead A unit, does it take off in reverse by itself? If so, the odds are that it's a defective slave board in the trailing A unit.

Hi Barry: No it only goes in reverse when plugged into Lead A + B units. It will go in sequence: Neutral, no forward, neutral, reverse. Mark
Bad Slave board most likely. Can be fwd fet, or the logic chips. Any abnormal rise in current when trying to go in FWD? G

Thanks G.....No, No abnormal rise in current. Puzzling. Regards, Mark
Had the same thing happen to one of the AGHR Kids' PS2 UP Coal turbine. Unit goes fine forward, but intermittently won't go into reverse. Suspected the slave board was going south. Was thinking of installing a PS2 board in it, eliminating the forward tether and consisting it with the forward unit.
Other thought was to pull the slave board from my Proto-2 FT ABBA set (thus ditching the tethers) and use that.
