I found that Q1 in the output circuit had failed. Got good pulses to the base lead with not transistor. Replaced and it works fine. The shock is a bit much for my 10 y/o

The instructions were "OK", however the parts list that jumpers be installed at R20 & R21. This is for the 4 pawn version. I had the jumpers on at first and got 4 flashes. Then all of a sudden...nothing. I am getting pulses out of the timer, but the copy of schematic is not real clear....
