thanks everyone, nice manual jkh, and jk i did find a power supply on eBay for 225. one of the other cars has a power one power supply that was wired to the drive, so either way i will get it replaced and see the outcome. of course ill be on vacation for the next 10 days, so it will have to wait. Kone indicated that they have a upgrade for that drive, has anyone out there upgraded this drive
