Electricity - «blood» engine management systems
Your Focus, like any other car, depends on electricity to drive: its subsystems, such as engine management, fuel injection or lighting, are completely dependent on electricity. With such a strong addiction, it is not surprising that many drivers associate unpleasant experiences with the trio of battery, starter and alternator. The reason for this is often under the hood, ie. in the workplace and in the peripheral nodes of these three main actors. For clarification, it should be said that the working conditions there are far from ideal. It is sometimes too cold, sometimes too hot, it can be damp or everything can be completely wet. Many consumers of energy are in unprotected places, so failures in the operation of on-board electricians are preprogrammed. In addition, sometimes batteries capitulate to bitter cold or extreme heat.
Most on-board electrical faults are easily fixed
After reading this chapter, you will no longer have a compelling reason to capitulate to «dead» switch or lamp not working. It often happens that only one wire connection has broken or the contact has rusted. Many on-board electrical problems can be easily fixed, even if you are not a professional electrician and do not have ambitions to become one.
