[SEL] sun engine tester help

[Bernie]

alright, this may be on topic or off topic depending on how you look at it.

Im looking for schematics and calibration data for a sun electric engine tester model 1120. This unit was made in the late 60's

Problem is i cant find any.  I was wondering if anyone on the list came across anything like this before.  

Either that or does anyone know someone who works for Snap-On, sun electric, or EquiServ?????

This unit was made by sun electric, but not to long ago snap-on bought them out, and EquiServ does the repair work.

Any help would be appreciated.

Thanks
