@Vernon Barry posted:Wire your Williams motors in series is one way to reduce your speed issue in conventional and lower current draw.Again, you are comparing an 8A capable ERR board, to a 4A board, in a loco known to draw higher amperage just because of the motors and factory gearing.
I'll concur with this statement, our single motored old school Williams 44 tonner easily draws over 2 amps pulling a modest 6-car freight load. You add an extra motor and a few more cars and the 4 amp limit can be found easily. It already runs like a rocket at 10 volts due to a poor gear ratio and there is no second motor to wire in series with to slow it down.
