Ironing out all the bugs on my pinbot, last issue is the MB is not working, ball wont lock in the lhs, spits it out after 30sec's or so, you can lock it in on the rhs no probs, shoot the new ball into the lhs lock nothing happens, 1min later lhs ball comes out,

basically i have done these checks all good,
solenoid test both sides,
switch edges test,
wiring continuity check from switch 25, 26 to IJ10 in the BB,
is it safe to say the issue is in the main CPU board

had a look in the quick search nothing there,
any info would be a great help

Well i didn't use the ball for the switch test, used a long tool to reach down the switch through the Visor, because when i tested it the visor was closed & targets was up so i poked a tool through the gap,
after reading your comment i tried it again with the visor down & pushed the ball up under the visor onto switch 25 & Holy Cow the switch did not register removed micro switch & adjusted it

I Appreciate your comment ufopinball, was just about to yank the board out to be checked,
thanks again for your input, you learn something new everyday
