The watchdog thing depends on how long the watchdog delay is. It couldn't hurt to do a feed between waits or even disable the watchdog completely for this test.

Also, have you properly wired the solenoid breakout board? I believe there is a power cable that needs to be running to that for it to actually work.

If none of that works try sending messages to the DS through the DriverStationLCD class. That should be working again if you have applied the Feb. 9 update
