Any way to know witch transistor on the node 8 is responsable for the right flipper?

Quoted from bobukcat:

You should be able to trace it fairly easy with an ohm meter. Turn the game off, clip one lead to the coil for the flipper and then start hitting the tab of each transistor on the node board. If you use diode test or other audible alert for 0 ohms it will make it a little easier.

Nice, are they easy to replace, my right flipper had a problem when i start the machine, got stuck on up and starting to get very hot, ive remove the connection of right flipper(ORG GRN) and ive use to the same wire of the upper right flipper (YEL BRN) to connect to the flipper and it works just nice, but of course i lose the ability to make Stage Flipping because i use the same transistor for both.

Quoted from bobukcat:

I wouldn't leave it like that, you're pulling double the current through a single transistor that way and it likely won't last long. I've never worked on a Node board so I can't answer how difficult it is to change the transistors but I suspect it's pretty doable.

Yeap i dont pretend to leave it like that, just a temporary "fix" that i pretend to solve as fast as i can

Ive seen on the manual and looks like that nodeboard 9 is the same as the node 8, can i swap them just to have sure that problem is on the node 8 board?
Thanks in advance
