OK, we are making some progress! So that component shown in photo has 4 colored stripes that look like (right to left) BROWN - BLACK - something - GOLD. Is the something BROWN, RED, ORANGE, or ?
And is/was there any possibility that with the 9V battery test that the lights might have been on but VERY DIM? By very dim I mean maybe you need to turn off the room lights to see it.
