no ac ripple on power supply, stragnge thing is i have only see it happen in the up direction. ran it down as many times as up, an only faults in the up direction.
guess sometimes thing just don't make sense, time to start changing parts. Looks like power supply first, will keep you posted. thanks half pick, did see the wiring change on some paper work i have, looks like the change had already been incorporated. but ds5 coming on does say power supply problem so guess i will have to keep it simple and change it out
