I just picked up a 1990 vintage Hunter F111 4 wheel computerized
alignment machine....price was right it was free. Cost 30K new, and
has 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.
