Sunbeam Model 7019A burning out extension cords
Hello, I'm looking for some guidance from someone who has restored or repaired a mower like the yellow Mastercut at the top of this thread. Mine is very similar, 12 amp, but says Sunbeam, not Mastercut across the front. I picked it up before the garbage truck did & I've used it for about 10 years.
I use it 3-4 times per year to cut the crabgrass at a vacation home.
Only problem I've had is keeping the extension cord plugged in. About a month ago, the female end of the heavy duty 50 foot extension cord that I've used for 10 years started smoking where it plugs into the mower. Used a different extension cord to finish mowing and put a replacement end on the cord.
Trying to eliminate the problem of the plug falling out, I got the bright idea to make a short extension cord that would stay attached to the mower in case the taking it on and off was part of the problem.
Did that and the next time I was mowing, everything was working fine so in addition to mowing I was mulching lots of leaves for about an hour when my new little extension cord started smoking at the female end, where it attached to the mower. This time in addition to killing my little extension (which might not have been heavy duty enough), the male "plug" on the mower is also burnt.
Am I correct that the male "plug" in the handle switch are actually called leads that can be replaced?
Does anyone know what might be causing this problem? I guess the mower is at least 30 years old but I can't find any info about it online. Handle/Power switch is similar to photo below.
Many, many thanks for any help or information!
