Paul,
Yes, C1 and C2 are for arc suppression while C3 is what's called a shock protection cap in double insulated tools. I think you missed the decimal point in front of my number. So my .25 uf is about right.
I'll read the links.
Any thoughts on the shock protection cap? I can't find any info on that name or by any other word combo I've tried. Yet.
It will be at least a week before I'll be close to needing it, maybe more!
Thanks,
Pete
Another edit: I know the caps aren't necessary for running. It will run fine without them. But I think that the brushes might last longer with them.
