Examine the flywheels on the motors. A PS2 upgrade requires that one of the flywheels has a sticker around it with black and white stripes.
Did you install the battery charger? Molex 2 pin type. The PS-2 upgrade would be a 2.4V AA type battery. The PS-1 a 8.4V (9v) type. G
No, I did not install the battery charger as I don't think I have one. Where is the battery charger port? What port is used for PS2 versus PS1? thanks.
It is where you put it. Look at your MTH upgrade instruction. PS-2 3V is a molex two pin port. PS-2 5V is round. But PS-1 and early PS-2 5V do not have charge ports. G
