Power to drill but doesn't work

[Fredstudio]

Thanks I'll try that tonight. If it is 0hms there any idea where to look next?

Where are the brushes on the drill please?

The brushes are the carbon blocks than connect power to the rotor. They press against the commutator, which is the segmented copper ring at the left hand end of the rotor (the bit that spins!) They are pressed against the commutator by the springs that push them into the brush holder

The connections to the brushes are shown in SUNRAY's post with the white line. If you don't get any continuity between those points ( turn the drill by hand whilst you check) then it's likely the brushes are worn or jammed in their holders, thus not making contact.

I personally have found the biggest failure in my powertools is the cable breaks as it enters the tool, with only one due to brushes - but that I put down to it having sucked in loads of brick dust. Others seem to have brush issues.
I've always made the assumption it's to do with the way the tools are used and abused.
Op has already replied with

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.

It could be the fault of course but I take to be a good sign.

As this is an 110v drill, has the OP confirmed there is output from the 110 transformer yet, with a meter? He should see 110v between the two poles, 55v between each of the poles and the earth connection at the 110v socket.

It's about 8 years old but hasn't had much use at all. Because I got Ohms at the white connections. This suggests the bushes are ok?

I don't think I have done that yet

But the transformer works with other tools.

When and how did it stop working? Maybe the motor is burnt out. Take motor out and follow youtube diagnostic videos for checking motor using multimeter.

 

[Fredstudio]

It just stopped working one day when I tried it. It hasn't had much use at all in 8 years. No real heavy use. Was used maybe 5 times a year.

 

[DiyNutJob]

Check motor following videos to rule that out as the problem.

I'll repeat this:

and suggest the continuity tests on the mains lead are easier than motor diagnosis.

 

[Fredstudio]

Thanks so that's test between the live and neutral as it enters the drill?

 

[SUNRAY]

no, test between the blue wire and the N pin of plug, then, test between brown wire and L pin of plug.

 

[Fredstudio]

The blue and neutral pin on the one 10 plug?

 

[Fredstudio]

Ah I'm with you so I am testing if there is conunity between the cable ?
