I'm finishing up the last bug on a Williams Toledo. The playfield lights for Extra Ball (1 in each inlane) and the spot arrow & 500 point lights for #6 and #7 targets are all blown. I swapped in new lights assuming they were just burnt out, but when the reset bank fires these lights all go super bright and typically blow out within 1-2 bank resets. Is it possible that there is a short from through the 115v bank reset bar to these lights?
Extra Ball is a tough one to troubleshoot because it's controlled through the A, B, C, D relay AND the #6, #7, or #8 relay based on jones plug adjustment. I'm confused because looking at the schematic, I'd almost expect #8 lights to have the same affliction, blowing on reset. But thinking back, the jones plug was originally set to a different adjustment and only the Extra Ball and #6 lights were blowing. I have it now on the 7 setting and both #6 and #7 are blowing + EB.
Any thoughts or pointers on what to look for on this one?
