They are placed in a hostile, hot environment and cannot be expected to last indefinitely. Another mode of failure is a shorted or open winding. This exhibits itself as a "dead spot" on the commutator. If a brush lands on a dead spot the motor wont turn at all. A third failure-mode is a faulty pinion engagement. Sometimes the pinion assembly gets stiff or stuck due to lack of lubrication or wear. Starter motor rebuilding or replacement is required for all of these problems.

Use a 25-65 watt iron for most work, and a 150-250 watt one for large cables, or an 8 oz (225 g) gas-heated iron. Working safelyDisconnect both terminals of the battery before doing any work on wiring other than testing. Whenever you work on the car, watch for any part of the loom coming loose from its clips, for there is a risk of it getting trapped or burned. Always replace wiring in its clips.

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.

The AWG doesn’t have high current requirements, but the board house doesn’t give you a discount for using less copper, so you might as well opt for large (= low-resistance, low-inductance) traces if you have the room.

Grip the cable, connector uppermost, in a vice or self-locking pliers, so that the connector rests on top of the vice and cannot slide down the wire when soldering. Inside a bullet connector. Apply solder on the top of the connector, and let it melt and run down inside. Trim off the protruding strands with wire cutters.

Some can carry more than one board hence allowing the processing of multiple PCBs simultaneously. Other designs have adjustments to support both the primary and secondary side processes.

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.

Dithering the stepper signal at a higher frequency than the motor can respond to will reduce this "static friction" effect. Because windings are better utilized, they are more powerful than a unipolar motor of the same weight. This is due to the physical space occupied by the windings.
