My friend has a Tristar MG1 vacuum. The cord was chewed by her dogs. I repaired the cord, matching black to black and white to white. It now sparks and trips the circuit breaker. I don't understand. I used wire nuts and electrical tape. I cut the chewed portion out so there would not be any shorts. Could this problem be inside the vacuum that we don't know about or is there something else I need to know. Thanks, kat
Chances are that there is the tiniest fray of one of the wires touching somewhere. Since you have already made a good repair with nuts and tape, feel the length of the cord for other bite marks where a puncture might short the cords. If you find such a site, **** the sheath lengthwise, tape the wires and replace them in the sheath, then tape the sheath closed.
