Two-year-old Black & Decker 19"

anything that runs on 240 volt power should only be repaired by a licensed electrician

Sounds like its burnt out. Or shorting out.

You should use a heavier duty extension cord. clear the black and scrape away and test again with a heavier cord.

no problem make sure it's unpluged and remove the screws that hold down the cover clean out and replace everything back on..good luck

Go online if you have a computer and type in Black & Decker 19" electric Lawnhog mulching Mower owners manual. I had good luck finding manuals that you can print right out.

All set, figured it out.

The rectifier is a flat plate with 4 posts that attach the electric wiring inside. You will need a flathead screwdriver to remove the four screws holding down the cover on your mower. on top where all the wires run (you will probably see one burned) There is a screw in the middle holding down the plate, you will need to replace the plate and resplice the wires that may be burned.

There are a few sellers on ebay for this switch (search for 681064). Some only ship to the USA.
According to some websites, Sears also uses the same switch for their Craftsman electric lawn mowers.

I have a Black and Decker Electric mower #M2370, which I would like to use this year before moving to a condo. Last year, the mower was stopping and starting depending on how the lever was positioned. I suspected the wiring so I removed the on-off switch lever. The wiring appears intact. Part of plastic inside the lever maybe broken. Can i use the mower without the lever by just pushing the black button?
