If you have a bad plug on a lamp cord, also called zip cord by some old timers, you can go to the hardware store and buy a replacement. Cut off the old plug and follow instructions for installing the new plug.
If you have a frayed or broken wire, you are better off buying a new cord, or if length isn't a problem, cut off the bad part and install a new plug on the remaining wire.
If you are dealing with a simple extension cord, your are usually better off economically and from a safety standpoint to just buy a new cord and disposing of the old cord. If the cord is hardwired into an appliance the techniques described.
Appliances cords are made of stranded wire because of the flexibility of these types of cords.
Most lamp wire is parallel #16 conductors.
By "clear insulation," I assume you mean the type of wire used in some lamp cords. If so, the hot wire is the one with the smooth (non-ribbed) insulation.
Electrical cords are insulated to prevent the electricity from going from one wire to the other wire without first going through the lightbulb or electrical device. Electricity is lazy. It would rather jump from the hot wire to the neutral wire and go back to the power plant without doing any work than have to go through the light bulb and do some work. You would still have to pay the electric bill.
50 amp 3 and 4-wire.
All are wires firmly seated? Did wires get crossed upon installation? Defective wire? Defective plug? WRONG Plugs?

Mark and remove plug wires. Remove spark plugs and install new plugs. Reattach plug wire to correct plug.
Possible vacuum leak or defective plug wire.
Defective spark plug? Defective plug wire?
You need to know the current to determine the wire gauge.
Most lamp wire is parallel #16 conductors.
Provides a way to keep cords organized
electrical = broken / rubbed wire. or defective pump. plumbing = broken pipe or bad check valve. either way you are hiring a plumber to correct problem.
You could have an ignition problem, such as defective spark plug wire or distributor cap or if it's an older car you might not have resistor spark plugs. I have also seen cars with defective alternators do this, as you rev the engine the noise seems to go to a higher frequency.
