Sun MDT distributor tester

Get some square stock or find a old screwdriver that has the same size square stock for the chuck.

Do not hook up a 12V battery to it you will fry the power supply and meters, prob some lights also. No idea why they did it that way just a MDT thing back in the day.

The tach is driven almost like a points set up on the main shaft in a small round box. Is it thumping when it turns? Also did you get the books from the guy?

He is going to call me on Monday so I can run up and get them.I dont hear a thumping just what sounds like bearing noise but that has begun to fade to about 1/2 of what it was when I firt plugged it in. I cant read the silkscreen good but when I switch the knob from what appears to be 8 lobe to the left 2 positions the tach steadys. I will figure something out for square stock next. I have the battery on a charger now and will run it again this weekend to see if I can get the dwell meter working
