Got a Gottlieb Big Brave a couple months ago. New to working on pinball
machines and am learning.
One flipper was weak / buzzed, some lights were out, and the center bonus
lights would have two (seven and eight) light up at the same time. I
resolved all of these issues by installing part of a flipper rebuild kit,
changing bulbs, and fixing one bent connection resulting in two wires
touching each other on the stepper unit.
The remaining ones are that the lower lane lights (both sets on left &
right), the rollover disc lights (all 3), the pop bumper lights (2), and
the bonus target lights (regular target lights work) do not light up. They
should light up at certain points to indicate bonus scoring opportunities.
The bulbs are fine. The scoring appears to be working fine. E.g. the ball
going over a specific rollover may score 100 points and later score 500.
It appears the machine is completely working except the lights noted never
come on.
Anyone know what I should check / look for?
I bought a schematic and understand most of it but not the part where is says NOT 3D in reference to the circuit that controls all of the issues noted above.
