Default Alarm system transformer + power supply (would both go bad atonce?)

That's a very nice find, especially since three things appear to have been blown
when I turned the power off without turning off the generator:

1. The ELK TRG140 16.5V AC transformer secondary windings are now open
2. The D135A battery-protection board cap is apparently blown
3. The Radionics D2212B alarm circuit board is apparently malfunctioning

The test of the Radionics board was to hook the battery directly to
the power and ground leads. That drew 98ma and the alarm system merely
beeped an incessant single beeeeeeeeeeeeeeep for the entire time that
I left the battery connected.
