I have a Delta 36-978…everything was fine last night and when I went to do my next cut I lost all power. The breaker and outlets have power, so it has to be somewhere on the saw. I unscrewed the switch and all seemed well there.

I did press the overload button but nothing seemed to happen.

Any suggestions where I should look on the motor?

do you have an ac meter? did you check to make sure power is going through the switch? I know you said that you unscrewed the switch and it seemed ok – but I didnt get from that if you meant visually – or if you actually checked it with a meter.

another thing to try is to take the belt off the pullies, let the motor run on its own (given that it does start) this will take the pullies, and blade assembly off the equation.

I do not have an ac meter…I took off the switch to check to see if something loosen up. I will try the belt thing next.

With no electrical meter troubleshooting an electrical motor can be tough. You can use a jumper wire across the switch terminals to check the switch itself. Not familiar with your saw’s motor but if there is a capacitor and it has either failed or gotten weak then a meter that can test the capacitance would be needed. Of course the worse case scenario would be that the motor has failed.

Is it set up for 110V or 220V?

Mike, since the motor looks to have a capacitor sounds like that’s what’s bad. You can disconnect the saw from the power source, and take off the cover to the capacitor and see if it smells burnt, or looks like its melted, those both are good signs its time to replace it. If you don’t have your owner’s manual, here’s a link to it for you.,36-978%2036-979.pdf

If you feel comfortable doing it, turn it on and give it a spin using the belt. See if it takes off.

Mike how goes it with the saw? If it is the capacitor I was at the Milwaukke Habitat For Humanity Restore the other day and they had a bin of motor capacitors for $3 and $5. Thet were 15mfd and 24mfd 400V. If one of them is the right value and that’s the problem I could pick one up and send it to you.

yahoo it is fixed!

My friend’s father came over with his meter and found out it was in the switch. Somehow grease go inside it…cleaned it, fired it up and away we go!

Be careful messing with the capacitor as they store electricity and can shock you after the power is off.
You might already know this but just a reminder. good luck

You got that right Dennis, that how the high school electrical teacher keeps his kids from sleeping in class, yes its mean and dangerous but I don’t think he’s had a kid sleep in his class that last couple years.
