I just picked up a 1990 vintage Hunter F111 4 wheel computerized alignment machine....price was right it was free. Cost 30K new, andhas EPROM upgrade from '06 when it was last used. It's a fairly compact and portable system so I'd like to fix it, but it's no longer supported by Hunter. Supposed to beep on power up and show a curser on the CRT screen. If I could find schematics for it would probably be a simple fix. Possibly just a DC power supply issue. Nice card rack inside with everything easy to get at. Display section seems okay, but no beep from the CPU board on power up, and no response to front panel push buttons. Wheel sensors and remote console power up okay. Tried cold start button on CPU board, with no luck. Pulled boards and cleaned card edges. Was working before being stored according to former owner. Anyone ever have or use one of these? If nothing else I got some nice sliding wheel turntables to use with my hand held camber gauge.
