A friend of mine who owns Jason's Bug Ranch in Winter Garden Florida has taken me to task to restore a old SNAPON MT-665 unit to full service, for which there is no schematic to be found anywhere, broken parts had to be fabricated, and other wonderful adventures along the way.



Heres the trailer for the project. After a head start the videos are buffered enough to start posting next week.

It would be nice to let us know what a Snap-On MT-665 is in the title.

I think Mr. Rubin wants us to keep our criticisms to ourselves.

The videos have started to be pushed onto youtube for a few weeks ive just gotten around to posting the links here, as i try to stay ahead. Edited in a way to also keep this dry troubleshooting event entertaining, having no schematic and no documentation on this unit. note that I am editing Part 8 and am way past anything you are viewing at this point.

Just a reminder to keep it civil.

Sun Electric was purchased by SNAP-ON in 1992. For the older Sun equipment Jaidinger Mtg. co http://www.jaidingermanufacturing.com/has many of the old repair manuals with schematics and troubleshooting manuals. It's possible they would have this info for your MT-665. You might want to give them a call.

I sent them an email, we'll throw it and see where it lands....

Most of the work was trace by trace to get through. and find out signal flow. Some was debuging more painful than others.

I'm a late comer to electronics but have been following this forum for years. I may have missed other threads but this is the first time I've seen the use of a neon bulb to test flyback transformers. Will this work for all flybacks?

Yes, the neon bulb will work. In the TV shop we just used a screwdriver to draw an arc.
