[Tumbleweed]

hello everybody,  at last a result , not only does it start 1st/ 2nd/ kick it also stops on the button,thanks to all your help.   I have cleaned/ scrubbed/ filed the earth all to no evail , taking note of how important the earth is ,i tested the carbon brush with my trusty  tester and a current wouldnt pass thro so i found another carbon fitted it  and hey presto problem solved (thanks for your offer ken) , wilko can rest now. what i cant understand is its the same brush that was in befor i had it repaired and it worked, they perhaps pack up suddely,     once again thanks everybody, great learning curve  tw

TW,
            Possibly a film of grease has impregnated the brush and caused the high resistance.
Maybe a bit of a rub with an abrasive on the working end may fix it.

Love it when someone gets a result.

Has the old brush been carved from some sort of resistor?

I had a Mag that somebody carved a pickup brush out of plastic?? I should have suggested another brush!

 Yeah, but if you had it repaired, how can you be sure it's the same brush that it had?? Maybe the repair shop got some bits 'mixed'..?

Good onya TW, great to see it's sorted.
Many moons ago I replaced the earth brush (same problem, couldn't stop it) with a carbon center of a C size battery. It lasted for about 10 years.
Cheers
