How can I prove whether the motor has burnt out on my electric circular saw?
I know how to use a multimeter and so I`ve checked the continuity of the L & N from the mains plug to each brush tip ( on the commutator) ( via the On/Off switch) and all is OK.
There is low resistance / short circuit across the brushes looking into the motor windings .
Does that mean the motor has burnt out as I thought that there would be an expected low resistance across the comm anyway.
How can I prove it?
Any suggestions?
TIA
