Dead Bosch GWS 8 115

[baffle]

Hi folks, long long time no post from me, but there again I've not been doing much in the way of steel work in recent years.
Been trying to get some maintenance done, and one of my Bosch grinders has died. No smoke or smell, it just falterered and stopped. I tried it again the following day and it turned on fine and then stopped and will not restart. I've continuity tested it and the flex is good, the switch is good and power is getting to one of the brushes (brown wire) but not to the blue. The brushes are fine and the motor spins freely. I think this might relate to the suppressor but I'm not sure. Any one any advice? I could try to bypass the suppressor?
Thanks in advance.

I bet one of the cores in the lead is broken.
Disconnect the lead in the grinder (after disconnecting from the mains) and give each core a pull and I guarantee one will come away.
Only think keeping it working in the insulation keeping the cores in close proximity.

Thanks for reply, appreciated. Have tested cores and they are sound.

I'd cut each end of the flex back 2" and re connect them. It's a very common failure. That at least eliminates the power cord.

Pretty sure my favourite grinder is a one of those. Brilliant little thing bar one annoying issue. The switch.

That's the first place I'd look. In fact if I was even wondering about a problem like yours, I'd just buy a replacement switch - from Bosch (!) and swap it out just in case.

If you do, do me a favour and post a link to one, I might just do that with mine anyway. Sometimes it latches, sometimes it doesn't and it is so awkward (I find) that sometimes I have to wrestle with the blasted thing.
