The cord that runs from the motor to the switch on the handle of my Black and Decker Electric lawnmower model mm675 has bare wires where it passes next to the pivot point on the handle. Actually it is worn where the latch stops the handle. I think I can replace the cord myself but was wanting to let you know of this problem. It seems like a design flaw and potential safety hazard.

the blade goes on first, then the washer and the nut, Tim

The "wedge" of the plastic lever wears, so you need to replace the lever or build up that section of the lever. Some cyanoacrylate (Super Glue / Krazy Glue) and a piece of a zip tie will work.

I would look in my owners manual and get the part number for the height lever and order a new one. You could also try and wire the height lever so it can not move. I am not sure how it engages but you could may be try and bend the lever so it is tight and won't move. Just a couple of ideas.

Good luck

I assume you mean convert it to corded, connected to the mains; cordless is electric as well.
It is possible but there are conversion losses as compared to using a 'native' AC corded mower motor.
It also depends on why you want to convert it. If you find the battery unit underpowered, adding a 12v power supply and cord will not solve that, it will just extend the run-time to continuous, assuming the motor does not overheat, as it is probably designed to match the battery run length for on/off cycle times.
You could consider trading, or selling yours and buying a corded mower.

change a new blade. when was the last time the blade gotten changed?

It sounds like you have a loose connection somewhere in the motor

open up the top cover of the mower & inspect the armature commutator & brushed if not broken.also checked for loose connection on the rectifier,extension terminal on the switch handle then the switch the last to checked ig any burnt on the terninals too. this are common probel may occur if mower not running.
