Wire And Connector Repair - Ford Ranger Maintaince And Repair Manual

Never use an ohmmeter with power applied to the circuit. The ohmmeter is designed to operate on its own
power supply. The normal 12 volt electrical system voltage could damage the meter!
1. Isolate the circuit from the vehicle's power source.
2. Ensure that the ignition key is OFFwhen disconnecting any components or the battery.
3. Where necessary, also isolate at least one side of the circuit to be checked, in order to avoid reading
parallel resistances. Parallel circuit resistances will always give a lower reading than the actual
resistance of either of the branches.
4. Connect the meter leads to both sides of the circuit (wire or component) and read the actual measured
ohms on the meter scale. Make sure the selector switch is set to the proper ohm scale for the circuit
being tested, to avoid misreading the ohmmeter test value.

Wire and Connector Repair

Almost anyone can replace damaged wires, as long as the proper tools and parts are available. Wire and
terminals are available to fit almost any need. Even the specialized weatherproof, molded and hard shell
connectors are now available from aftermarket suppliers.
Be sure the ends of all the wires are fitted with the proper terminal hardware and connectors. Wrapping a wire
around a stud is never a permanent solution and will only cause trouble later. Replace wires one at a time to
avoid confusion. Always route wires exactly the same as the factory.
If connector repair is necessary, only attempt it if you have the proper tools. Weatherproof and hard
shell connectors require special tools to release the pins inside the connector. Attempting to repair these
connectors with conventional hand tools will damage them.
