I was messing with the Mars light and unsurprisingly, the motor is toast and won't move w/o a little assistance. I was mostly testing on the bench with variable ac power supply but after swapping in donor, found loose connection J123-4 blue/orange on driver board as well (fixed that).
The manual has the wrong voltages documented but this diagram from pinside thread clears it up.

While I had my donor out, I wanted to document the motor hack someone did on it. You can see my project getaway lamp on left that has lots of pitting from rust. Anyway, the replacement motor on right is a 12v DC motor. WMS went through a lot of effort to take dc power convert back to AC and add resistors to further drop voltage down for stock motor. This one needs it converted back to DC which is done with the diode wired to unused pin on J1-3 and then J1 and J2 are basically swapped in cabinet with 16v coming into J2. This puts @ -8Vdc to the motor which seems to work fine; even in the game there is only about 7.5vac at lamp. In game it might be different or the voltage drop is due to load of motor and lamp.
