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.

Spread out the cuts across a bundle of several wires: if many joins are opposite each other their bulk may make it difficult to fit the loom into the car. If possible, replace wiring with new wire of the same colour. The new wire must be the right size: there are five sizes, depending on current rating. Repairs in wrapped sections of the loom are the only places where you may join wires by twisting them together and soldering the joint mainly because there may not be room for any other method.

I think that this approach results in an easier design process and a better board. The AWG layout progresses from left to right: from power input and communication input/output, to the power supply circuitry, to the processor, to the DAC (which is controlled by the processor and constitutes the board’s transition from digital to analog), to the analog signal-conditioning circuitry, and finally to the output connector. Parts that don’t have a specific position in the functional flow—such as the oscillator (U4), the DAC’s passives (C16, R5, etc.), and the voltage reference (U3)—are arranged near the components that they support.

Before you disconnect anything, make absolutely sure you know how to put it back. Number both sides of each connection with labels made of masking tape. If necessary, make drawings of cable routes and how clips fit. Use a craft knife or razor blade to cut away the wrapping from the damaged section. Take care not to cut into the plastic cable insulation.

Splices may be used within 30cm of a termination device when attaching to the pigtail spare lead of a potted termination device, to splice multiple wires to a single wire, or to adjust the wire sizes so that they are compatible with the contact crimp barrel sizes.

However, each new board design requires its custom fixture which can take between three and four days for a manufacturer to produce and deliver. As such, using fixtures can add up the costs and time to produce the PCBs.

The damage caused by overheated wires is easy to find; but if only a single wire has overheated and melted at some point, you may have to use a circuit tester to find the break. If the damage is in an open run of wiring, you may be able to mend separate wires without taking out a section of the loom. If it is in any part of the covered sections, you need to remove at least part of the wiring loom.

Push a screwdriver blade through the grommet carefully to enlarge it for the new cables, taking care not to damage insulation on existing wires. If you pass a cable through a new hole, fit the hole with a grommet. To pass wires up door pillars or behind trim, tape them to a piece of fairly stiff wire, poke it carefully behind the trim or up the pillar, and pull it through at the far end, bringing the wire with it.
