Cannon speed went from fast to almost no movement at all.
SOLUTION: I wish I had taken a picture of this before it was fixed! The big ceramic resistor (on the left of the picture just to the right of the two wrapped coils) was missing. It its place, however, was a #44 bulb! This bulb would get very bright right around the same time the cannon would basically stop moving. After discussing this with a very knowledgeable ASIC guy I know (thanks Charles!), I learned that light bulbs are very peculiar resistors. Specifically, the resistance will change as the bulb heats up. The bulb was very quickly heating up and the resistance was becoming very high. The end result was that the motor was turning very slowly because the resistance was so high.
With the help of rec.games.pinball I was able to determine the appropriate resistor. Strangely enough this information is not included in the T2 service manual. In case you are wondering, the board with the ceramic resistor and the two coils is called the EMI board. It should have an 11 Ohm, 5 watt, 10% sandohm (power) resistor installed at R2. Also, R1 and W1 are not populated.
I was unable to find a 11 Ohm resistor quickly, so I replaced it with a 10 Ohm resistor. Given the 10% tolerance, I doubt there is any noticeable difference.
