Power to drill but doesn't work

[Fredstudio]

Would anyone have an idea why this boss 110v drill may have stopped working. I have taken apart to see if was a loose connection but can't notice any thing. I have had a volt stick near it and it picking up power all the way through. Thanks for any help

Power all the way through the drill press the button and nothing.

Power to here

useless.

Do you have a multimeter?

 

[Fredstudio]

I do yes

I do yes

Then use that for testing voltage. A voltage stick can show static charge as well as mains voltage. An electrician I was working with said he put one on a wooden coffee table and it lit up.

Are the brushes free to move in their holders and making contact with the commutator?

 

[SUNRAY]

I do yes

In that case as a starting point do continuity measurements and look for 0Ω (zero ohms) across the three points shown as lines in brown. blue and white:

By that I mean put one probe at each end of the line.

OF COURSE IT GOES WITHOUT SAYING THAT SUCH TESTS ARE DONE WITH POWER OFF/NOT PLUGGED IN.

Sorry just realised this is 110V so it'll be a yellow plug.

I was literally about to ask you about this, will it still work, presumably it will.

Where are the brushes on the drill please?

Thanks so I test continuity at these points without the power on?

So, to answer your question, yes

So between the two white wires I got 0ohms well 00.6 is that close enough. I can't get a reading in the live and neutral incoming I think I'd need to pull the wires out.

Good, that points to the brushes being OK.

Try a dress makers pin or something similar to reach the metal contact beside the wire, avoid removing them unless you need to.
