I've recently acquired a TAF, it was dirty (but running) so I took it apart and have been cleaning it.
I have not cleaned the playfield yet, however, I have cleaned and reassembled all components in the cabinet and the backbox.
Without reinstalling and connecting the playfield, can I run individual component diagnostics? Simply to check the components I have reassembled so far. Should I even attempt it? Or is it a bad idea even to hook up power w/o the playfield?
Thanks!
