Guess it depends on if it’s a model of a right-hand drive vehicle or left hand drive. But the “right hand rule” is the same regardless of which side the driver sits on. It;s the one on the gith if you are standing on the vehicle facing the front, which is either obvious in the case of most cars and trucks, or may require a little inventigation with some locomotives, especially first generation road switchers, since some railroads ran them ith the long hoods forward, and others ran with the short hoods forward. If they are ACCURATELY decalled, one end with have an F or 1 on the frame at the front.
Just by looking at the wheels on your model, it would appear that it has dual wheels on only one end, that would be the back. Making the “right rail pickup” the one on the stack side.
The rail pickups technically don;t matter, it’s the polarity of the motor wires. Assuming the thing moves forward when the right rail is positive, then the orange wire from the decoder should go to the side of the motor currently connected to the right rail. If it goes the wrong way, you can either unsolder and move the wires, or adjust CV29 to make it go the right way.
I just installed a Loksound decoder, keep alive module, speaker and working lights in two of those models !
The right hand pickup from the wheels is grounded through the chassis. You can see where the motor itself has one brush grounded to the chassis. You need to remove the ground lug from the motor. The orange and gray wires from your decoder will go straight to the motor. The black wire will attach to the two wires coming from the wheels and the red wire will attach to the ground on the chassis.
Nice truck really … but just can’t understand the reasoning behind those funky wheels ! I plan on doing a wheel swap with a set of Herpa wheels and tires when I get some extra time.
