I'll send you over three 18V motors Gary which hopefully you'll find some use for. They're from a different manufacturer and as far as I'm aware haven't seen the same type of failure before.

The same applies to anyone else who thinks they've got similar issues with the 24V motors, if you can either take a picture of the brush holders as Gary has done and message it to me or send the motors back to the address here with a return address included then I'll have the same number of 18V replacements sent to you.

Sorry about the thread hijack!
