To turn on the cab light and magnet 4 has to be connect to power, which is 6. This is done on the switch in the middle of the controller. In your photo 4 is probably on the opposite side from where it should be as it going to the upper and lowers switches, which control motor direction and the clutches.
In the photo there is no way for me to see how the buss bars are connected to the switch blades, so it is hard to tell how it should be wired from the picture. I would suggest you look at how it operates and figure out where the errors are.
To make something happen the motor has to run and one clutch has to be energized. The motor is a double wound field arrangement so to make the motor run one way power one field, to go the other way power the other field lead. The motor field leads are 3 and 5. At the same time either hoist or rotate has to be selected by energizing one clutch coil or the other. The clutch coils are 1 and 2.
Power to everything is 6. The magnet and light are 4. So exclusive of the the 4, the push buttons should make up four combinations, 1-3, 2-3, 1-5 or 2-5, each connected to 6.
Just a guess is that 1 and 4 are reversed from where they should be. Just be sure that 3 and 5 do not get energized at the same time. That could burn out the motor.
