I have an older (Model 1113.236400) Sears 20 in scrollsaw which needs some
TLC. It is a variable speed which uses an encoder on the motor. Does
anyone know where I can get a wiring schematic for this saw?

Thanks.

i checked www.sears.com and looked up parts via model number
113.236400 and found that your owners manual is available for $7.49 from
sears... buy it if you dont have it...

Since you're looking for a schematic I assume the TLC required is because the
saw doesn't run.

I see from the Sears parts list for the saw that it uses uses a "control
board". Any schematic will most likely show the inputs/outputs, but will not
show the printed circuit breakdown. Sears also has a nasty habit of using an
acid wash to remove the manufactures ID's from the chips, making it very
difficult to repair the board, forcing you to order a replacement board from
them. If you suspect the control board may be the culprit check to see if you
can identify the parts used (manufacturer's part numbers). The control board
from Sears runs $150.

I ran into this problem with a Sears dishwasher and the bad circuit board was
90% of the cost of a new dishwasher.
