If an outlying part of the loom with few wires has been damaged, it may be simpler to replace each wire to the end of the loom instead of inserting a section. If so, use the old, damaged wire as a guide to the length of the new. In an open area of wiring, join old and new with snap connectors.Fitting new wiring Fit a rubber grommet when passing wires through a new hole in the bodywork. When you fit accessories you must use large enough cables. As far as you can, route the new wiring along the course of the existing loom, using the same clips and grommets.

Although this device uses an I2C interface with communication speeds up to 1 MHz, two of the eight pins are dedicated to Alert (pin3) and nReset (pin 6). The Alert pin is intended to be connected, if desired, to an interrupt pin on a microcontroller. According to section 3.5 (ALERT Pin) of the datasheet, "The output of the pin depends on the value of the temperature reading relative to programmable limits," and its function is "explained in a separate application note.

What is commonly referred to as microstepping is often sine–cosine microstepping in which the winding current approximates a sinusoidal AC waveform. Sine–cosine microstepping is the most common form, but other waveforms can be used. Regardless of the waveform used, as the microsteps become smaller, motor operation becomes more smooth, thereby greatly reducing resonance in any parts the motor may be connected to, as well as the motor itself. Resolution will be limited by the mechanical stiction, backlash, and other sources of error between the motor and the end device. Gear reducers may be used to increase resolution of positioning.

As the motor rotor turns, a sinusoidal voltage is generated proportional to the speed (step rate). This AC voltage is subtracted from the voltage waveform available to induce a change in the current.

The current in a winding needs to be reversed in order to reverse a magnetic pole, so the driving circuit must be more complicated, typically with an H-bridge arrangement "however there are several off-the-shelf driver chips available to make this a simple affair". There are two leads per phase, none are common.Static friction effects using an H-bridge have been observed with certain drive topologies.

A micro controller or stepper motor controller can be used to activate the drive transistors in the right order, and this ease of operation makes unipolar motors popular with hobbyists; they are probably the cheapest way to get precise angular movements. For the experimenter, the windings can be identified by touching the terminal wires together in PM motors. If the terminals of a coil are connected, the shaft becomes harder to turn.

The ease of loading and unloading the PCBs, as well as the ability to handle multiple PCBs, are important in high production lines. In addition, fixtures should provide thermal protection to the heat sensitive areas of the PCB.

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.
