thanks dj. I will try the switch test tonight. the claw optos are a hssle to get to as every single ramp has to come off to get to them. also they are definately closing before the claw gets to its end position when it does fail. ive also read that some people had re-seated the roms as when the claw fails the claw countdown stays at 9 and doesnt countdown! so i might reseat all of those tonight as well as the seller swapped the original roms with the swear roms. hopefully one is quite seated properly.
