UPS delivered my second GG-1(#1 is Green, #2 is Tuscon). I heard a load bang from my inclosed front porch. I seen the UPS truck drive away. UPS dumped off my new engine .
I set up my initiation track and added the engine to my list in the controller.
I read and reread over the instructions on how to install the pantograph.

One problem. What side of the GG-1 is the front. No clue given in the instructions. I toggled back and forth. The maker lights change from green to red and back.
Then I move the actuator backs apart. Then I carefully installed the (what I though to be the rear). Then I pushed the directional button and attempted to move the actuator blocks apart. They did not want to move.
I toggled the direction button several times. Nothing moved, the installed pan did not move.
Finally I was able to separate the blocks. I installed the Pan.
I placed the GG-1 up on my track. I applied power and pushed the “start up” button.
After playing around a bit. I realized and not mentioned in the instructions. There is a front and back, at “start up”.
The side away from smoke stack is the rear. That is the side ‘half’ where the access hatch is.
The pantograph did not work again.
I took the engine down and placed it on my initiation again. I removed both pans. I hit start up. I checked to make sure the blocks were apart. I moved them apart. I installed the pan.
Confusing
I pushed the “S2, MOP” button. This is what is displayed in the screen.
“F with an up arrow,” “F with down arrow,” “AUTO”,
