NC Scroller Posted August 1, 2015 Report Share Posted August 1, 2015 I am blessed to own several scroll saws. The other week my favorite Dw788 blew the fuse. Put in a new fuse and the same results. Tried a slightly big fuse and pop. I am a kinda handy guy but not an electrical engineer. I can ready a meter. I need help determining the issues. I am guessing it is the motor or the circuit board. Any one have suggestions on how and what to test. For the record I got this Model 1 in a yard sale 5 years ago. It had never been used and i paid $125. The saw now has lot of hours so it really does not own me anything but stll I really like how it cuts. Quote Link to comment Share on other sites More sharing options...
amazingkevin Posted August 1, 2015 Report Share Posted August 1, 2015 Look at the motor brushes first. oneleggimp 1 Quote Link to comment Share on other sites More sharing options...
ike Posted August 1, 2015 Report Share Posted August 1, 2015 I agree with Kevin , if they are ok take a volt meter set it on residence hold one cord to a wire of the motor and tthe other to the motor frame this will test the motor for a short, which is usually the problems with the motor.. you should get no reading on the ohm meter.

heppnerguy Posted August 1, 2015 Report Share Posted August 1, 2015 Could maybe have a wire that is not fastened well or has come out of a holder keeping it in place and caused the wire to rub against a moving part and could have worn away a part of insulation on the wire causing it to short out. Just another idea to look for. A meter wil show if there is a short in any specific wire. Good luck Dick Heppnerguy Quote Link to comment Share on other sites More sharing options...
