I have a Karcher power washer which was left outside over night. An animal chewed threw the power cable and so is unusable. I was wondering how to re-connect the power cord together, safely. I do not want to cross wires and use electrical tape. I was thinking of using a connector, but unsure of whether to use a two pinned or three pinned connector.
You can install a plug on the cord to replace the one that was chewed off. Choose one with the same number of prongs as the cord has wires (2 or 3). Be sure to attach each wire to the correct terminal! Splicing the cord is also OK, and tape would not be a problem if applied properly, but I prefer to use heat-shrink tubing. When I do a top-grade splice, I first twist the wires tightly together without making a tail, then I solder them.
