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.

Where they run through a hole, the sharp edges are lined with a rubber grommet. Sometimes the loom is divided into sections joined by multi-pin plugs and sockets, so that it can be removed and refitted section by section.

A stepper motor is a polyphase AC synchronous motor (see Theory below), and it is ideally driven by sinusoidal current. A full-step waveform is a gross approximation of a sinusoid, and is the reason why the motor exhibits so much vibration. Various drive techniques have been developed to better approximate a sinusoidal drive waveform: these are half stepping and microstepping.

Since the finite-impulse-response (FIR) filtering is a common operation in DSP, we will continue our discussion based on examining the difference equation of an FIR filter. This simple example will show the typical properties of many DSP algorithms. After reviewing the problem of handling the incoming samples, we will discuss the circular buffering as an efficient solution to the problem.

Brushes are used to create electrical contact to the commutator segments and when current is fed into two of the four brushes, it flows through all the loops of the armature and shoe windings and out the other two brushes. This creates a magnetic field around each loop. As the armature turns, the loop will move to a position where the current flow reverses. This constant reversal of current flow allows the armature and field coils to repel each other and spin the motor. The greater the current flowing in the coils, the greater the magnetic forces, and the greater the power of the motor.

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.

Care should be taken when depaneling the perforated-tab PCB array; otherwise, an incorrect method will splinter or tear the solder-mask or active surface layer. The ideal breakout method should not cause any damage to the board or transfer stress from the PCB surface to the components.

When the plunger is pulled into the coil all the way, the pinion fully engages the ring gear. When the ring gear is fully engaged, engine cranking begins. When the engine starts the hold-in coil will cut out and the plunger will move out, retracting the pinion and opening the starter switch.
