Hi Noel, Robert

I get very confused sometimes when trying to post reply messages. At First it was as though I was not logged in and could NOT type anything, I think I ended up trying again as a new member then found the title but none of your new messages were displayed until after I had sent mine.

I thought those two capacitors looked like Electrolytics, something to do with the Rectifier perhaps.

Thank you, You were both correct, I had made a serious error wiring it up and I am an idiot for not doing a thorough check. good lesson for you Noel, when you get to the testing stage.I knew something was wrong but missing a wire was a dreadful error. My Bench grinder seems ok. I ran it four times on the Start Capacitor for no more than 5 or 6 Seconds on each occasion. perhaps I got away with it, I have read somewhere but can’t remember where, that more than a couple of Seconds running on a Start Capacitor can destroy a motors windings. I rescued that B&D 7″ 3 phase Bench Grinder a couple of years ago from a skip  the stones thrown in seperately and luckily they had put the nuts and washers back on the spindle. no idea why they threw it away, Although the tool Rests are missing, AS ARE THE END COVERS  does anyone have a grinder like this that they could take a picture of the tool rests for me, to give me a rough idea what to make
