Have a High Speed that burnt out lane kickback solenoid . replaced solenoid and the little square relay switch box under it, checked wires, roll over switch, replaced burnt Q7, Q3, SR5 and all transistors and resistors on mpu around it that were iffy. It now works but stays energized constant and cant figure out what drives it or what to replace next. I have to unplug the blue wire on the little square relay to deenergize it so it won't burn again. any help would be very appreciated. Everything else on game works perfect.

How is this a different question from the one you posted yesterday? https://pinside.com/pinball/forum/topic/high-speed-out-lane-kickback-help

Please don't post the same question twice. It's hard enough keeping up with all the traffic on the forums without people duplicating content.

You're gonna wanna double check your work first. Make sure the coil is wired properly, make sure the transistors aren't installed backwards, make sure there's no bridged solder joints, and that you put in the right parts.

If everything seems good, then you might have a problem with the resistor bank SR4, and/or U17
