Before cutting out damaged wires, make sure that the colour coding is the same at each end of the damaged section of each wire, and that it is not so discoloured that it is unrecognisable. If there is any chance of confusion, label both ends.

Test each mended wire with a circuit tester and battery, connected to the nearest connectors either side of the mend. Re-wrap the exposed section of the loom with self-adhesive or "clingfilm" PVC insulating tape. Put some layers between the exposed section and adjoining wires - not merely a cover over the top - then fit the loom back into the car. Reconnect all terminals and clips, then test all the electrical components involved.

There may be some resistance that feels like removing magnets from each other. Underneath the cup of all outrunner brushless motors is a series of coils. On some motors, between the coils, are hall effect probes. Hall effect probes detect the spinning magnetic field and provide a pulse out of the brushless motors to the electronics. From this pulse the electronics can precisely control the speed of the motor

SMT fixtures are rigid PCB carriers that allow manufacturers to load single or multiple irregular boards, and then take them through the standard processing machines. This makes it possible to carry out tasks such as automatic mounting of electronic components, infra-red reflow soldering, wave soldering, automatic testing, etc.

Making repairs to the loom Use a circuit tester to check if single wires are damaged. The wiring loom itself seldom goes wrong, but after other repairs have been made, a cable may be trapped and its insulation cut through, causing a short circuit.

Use a wire stripper to remove about 1/8in. (3 mm) of insulation from the end of the wire. Lay the bare strands in the inner section of the connector. Use crimping pliers to tighten the two small tongues firmly around the insulated part of the wire. On the other side of the connector, push the wire strands back and down flat. Hold the connector blade upwards to avoid solder running into the spade part.

The datasheet goes on to say that "the nRESET pin is internally connected to VDD with a pull up resistor of 50 kΩ." So... why are there two options for how to configure the nReset pin when it is not being used? Why not just recommend that it should be left floating (since it is already pulled high internally)? And, if there are indeed technical reasons for when the pin should be externally pulled up to VDD (for better noise immunity, as an example) then let us know what those technical reasons are.

A lousy wiring job will keep your electrical accessories from operating at full potential—and that means subpar performance. Many people are intimidated by the prospect of wiring a vehicle. But a proper wiring job doesn’t have to be a scary task—we’ve put together a few tips to help make the job a little bit smoother.
