Tron chaser,
Was an AT myself, VA-46 Cecil Field.
At least one of the solenoid control lines should have 12v or whatever they're using for control voltage. You'll have to back-track to find where it comes from and where it's getting lost. The "mode" switch should just change the terminal connections on the xfmr for the various taps. Control power to the solenoid likely comes from the timer switch, before that, you're gonna have to hunt it down. Look for the obvious first, broken wires & corroded connections. Just fixed a little wally world special for the neighbor, corrosion on the little voltage regulator PC board ate a bit of the copper foil and opened the connection - some cleaning and a drop of solder put it back in business. You're getting 12vdc from somewhere which means whatever is preventing the output is likely not a major problem. If it's the timer switch that's bad internally, some of them old ones can be carefully opened and cleaned and/or repaired without too much hassle. If not, you can get a generic twist timer switch at any decent commercial electrical/electronics supplier (do not go to radio shack! I've yet to see anything they sell that's worth bringing home let alone paying for)
