Looking for a jumper spot negative side for my pcb board. Mistakingly knocked off the negative pad for the motor to push and pull the game discs Update (05/30/2022)
from this pic the black or negative pad is gone. Can’t find a good tracer. But your right it’s just the ground from the negative side of the motor of the disc drive.. looking to jump or place the black or ground in a place to complete the circuit. Thank you
Check if there is continuity between negative and board ground, it is possible that the negative is just ground. If not, you need to find the output positive/negative of the motor driver and jump the wire from there.
