I found a Metabo angle grinder and it's super dead. Turning it on does nothing. No crappy running, humming, sparks or smoke. The brushes are ok, so is the wiring to them. I tested the switch and that's fine too. It could of course be the motor or armature, but I've got one thing left to try. The grinder has a speed controller. What I want to know is: can I get rid of the speed controller and just hook up the switch to the brushes? I have had plenty if cheap crappy grinders without any speed control and they do exactly that. It's just a switch and a capacitor. IF I can get away with it, I should probably wire a new capacitor too right? I have a couple lying around from said crappy grinders. Those grinders are about 1000W, the Metabo is about 1400. Is that an issue?
I've posted a picture below of the insides. I think the red wires are feedback to the speed controller.
