First, let me note that the time that a coil is pulsed while in diagnostics is different than the time it's pulsed in game play. Each coil has a "game play pulse duration" programmed into the software. But during test, they may all be pulsed for a fixed duration. Makes sense...doesn't it?
Next, have you measured the actual voltage at the weak coil.
Compare that voltage to the voltage for another coil like the pops or slot machine eject.
Any difference?
