I’m trying to crimp ring terminals onto some wires for a project, but I'm not sure if I’m doing it correctly. Can anyone provide a step-by-step guide?

To properly crimp a ring terminal, start by stripping about 1/4 inch (6-7 mm) of insulation from the end of the wire using a wire stripper, taking care not to damage the wire strands. Select a ring terminal that matches the wire gauge you are using and ensure the terminal's ring size fits the bolt or stud it will be attached to. Twist the stripped wire strands together and insert the stripped wire into the barrel of the ring terminal until the insulation touches the barrel.

Next, use a crimping tool designed for the type and size of the ring terminal. Position the barrel of the ring terminal in the correct die or slot of the crimp tool, ensuring the terminal is positioned correctly with the wire fully inserted. Squeeze the crimp tool handles firmly until the terminal is securely crimped onto the wire, making sure the wire is securely held by giving it a gentle tug. If the terminal is not pre-insulated, use heat shrink tubing or electrical tape to insulate the crimped connection. Slide the heat shrink tubing over the terminal and apply heat to shrink it in place, ensuring a safe and reliable connection.
