Before I bury him, is he really dead?
 
Today I made about 20 cuts of 2x4 with my old Skill circular saw, not a very big project compared to what we've put it through in the past. I took a break, came back for some more and the saw won't start. I switched the plug to a different receptacle, and yet again the saw won't start. So I try a third receptacle, same deal.

Thinking it was the saw making the problems, I plugged in my jig saw instead, but...yup, doesn't start. Then I realized my good ol' circular saw must be at fault here.

So I checked the breaker, and low and behold, all three receptacles I had plugged my saw into were tripped. Did some more testing and I've established my ol' saw has short circuited somehow. Is it a goner, or an easy fix?

Is this a worm drive?

If the saw is worth fixing--start with the cord---that's such a common cause with circular saws---

Then check the brushes--next--the switch--

Worm drives are usually worth fixing---

I'm gonna assume this isn't a worm drive. If it was, you'd knoow it was worth fixing.

I'm guessing here, but...
High amp draw means either a short or a stall. Can you turn the blade by hand? Is there a sliver of wood jamming it? Bad cords, brushes and switches usually open, not short. Does the saw smell burnt/funny? The drive pinion on those Skil sidewinders is built onto the armature, so a bad gear may mean you get a new saw. A siezed bearing might be repairable.

I'll take a look today. Thanks for your help.

First, check on the price of new saws, the price of parts for your saw, and figure out how much your time is worth. How "dead" your saw is depends on all these factors.

Parts prices are usually designed to put you on the "repair/replace fence", and makers know better than any of us what those prices are because they have the resources to do the marketing studies.
