Emergency Electrician & Locksmith Services in Worcestershire

The vehicles we drive today are becoming increasingly sophisticated with advanced electrical systems that enhance and automate your driving experience. Unfortunately, when problems arise with these complex systems, fixing these problems is beyond the expertise of your general car mechanic. Auto electricians based in Worcestershire are the experts you need to contact to get electrical faults fixed, as they are equipped with state-of-the-art diagnostic equipment, which enables them to identify the source.

Common Electrical Problems With Vehicles in Worcestershire 

Engine control units are the computers that connect with your engine and decide almost all aspects of it. This includes horsepower, torque and how much fuel you need to pump. It should be repaired by a Worcestershire-based electrician if it goes wrong. Do not ignore an ongoing problem with the ECU in your vehicle as it will likely worsen if you do not fix it. The issue could be a simple fix for a Worcestershire electrician or something more serious.

How to Repair an Electrical Control Unit

There are several steps to repair an Electrical Control Unit. The first step is to identify the faulty part. Sometimes, a simple replacement can fix a problem without causing any further harm. For example, replacing the faulty cable can improve the function of the control unit. If the problem is with the software or hardware, replacing the faulty part with an alternate one can fix the issue. However, it is important to replace one part at a time. Replacing multiple components at once will make it harder to determine which part is faulty.

Problems with a faulty ECU

A faulty electrical control unit (ECU) can cause many different problems with your car. A bad ECU can cause a car to stall or even shut off. It can also cause reverse polarity jump starts. It is important to know what to look for to tell if your ECU is the culprit. Here are some of the most common symptoms of a faulty ECU.

First of all, you may notice a drop in the engine performance. A faulty ECM can throw off the timing and fuel settings of the engine, which can negatively affect engine performance. Fuel efficiency, power, and acceleration can all be affected by a faulty ECM.

Another symptom of a faulty ECU is a check engine light. While a malfunctioning ECU can be difficult to diagnose, it is important to check the light along with the symptoms. Other signs that your ECU may be faulty include stalling and misfiring. These problems can be intermittent or consistent, depending on the severity of the problem.

Dealing With Electrical Faults in Caravans

It is possible to experience electrical faults when you are using your Caravan. You may have problems with your Leisure battery or the wiring in your Caravan. You may have to check fuses or leaks. In some cases, the fault might be an exposed lead. When this happens, you should find a safe place to place the exposed end.

Checking for leaks

One of the most obvious things to do when dealing with caravan electrical faults is to check for leaks. Leaks in caravans can cause serious damage, resulting in mould, rot, and other problems. If you notice leaks, they should be fixed as soon as possible.

To check for leaks, you need to unplug the electrical system in your caravan. The plug should be straight and clean, without rust. Also, make sure that the cable is in good condition and does not have a ripped cover. Likewise, check the bulbs to ensure that they are working. If they are not, you might need to replace them or clean the contacts. If the leaks are small, you can apply a silicone sealant to fix them. This type of sealant is widely used by construction professionals because of its strength and elasticity. It can also hold up better against leaks than other types of sealants. But remember to use the right type of silicone sealant for your problem. You should use acetic cure silicone sealants for interior repairs, and neutral cure ones for exterior fixes.

In caravans, leaks usually start around windows, such as the front window, or along seams. You can use a moisture meter, which can cost as little as £10. The normal moisture level is about 10-15%, so a reading of 50% indicates a leak. Checking for leaks in your caravan is a great way to avoid further damage and costly repairs. Water leaks can lead to rusting pipes, buckled flooring, mould, and mildew. A cracked shower tray is a common source of leaks. To fix it, you can apply a waterproof sealant to the area, or take it to a fibreglass repair specialist for further assistance.

Issues With a Boats Electrical System

Four possible causes of most problems in marine electrical systems are poor maintenance, inadequate battery capacity or inefficient charging systems. Saltwater and water ingress are common, and contacts can be corroded quickly by saltwater. Connections that are not cleaned well or have loose connections will cause resistance to increase, which can lead to progressively lower power. It would help if you cleaned the contacts with wet and dry paper until they are shiny. Find out if there is evidence of water intrusion and remove the source. Be sure not to mistake a dead battery for one that has just run out of juice. Although an old battery might give acceptable voltage readings upon charging, these will quickly fall when even a slight load is applied and eventually become flat again.

Fault Finding

It is important to use logic as much as you can to avoid failure. Sometimes it takes a lot of persistence to find an obscure problem, and however, it is easy to ignore an obvious problem. If the navigation light is not working, check for a fuse or circuit breaker. The problem is likely to be caused by a bad bulb, and it can be easily replaced if it has blown, as indicated by broken filaments in the glass case.

A voltmeter can be used to determine the voltage at the contact points of the lamp unit if the bulb looks intact. You will need to trace the wiring to find the fault in the circuit if power is available at the switch panels but not a unit. This will vary depending on each boat, as some may have multiple joins in their wire. A boat with separate green and red pulpit lamps will be equipped with a junction box at the bow. This is where power from one supply panel can be split to provide the required energy to each lamp. A junction will also be provided for the supply of the stern lamp.

To check if a part is in danger, a meter can be used to measure its resistance (O). To make the component work, the electrical current has to flow through it at its most basic level. A small amount of current is passed through the device to be tested by the resistance function. It records an infinite resistance if no current is flowing. This indicates that the component does not work. Before testing for resistance, components should be disconnected from 12V power supply.


Most marine engines have a belt-driven alternator that produces between 40 and 60 amps, and this same belt drives the freshwater circulating pump. Maintaining the charge of the battery is crucial by checking the condition of the belt and the alternator. Although alternators do not require much maintenance, it is essential to maintain the correct tension of the belts so that the battery can be properly charged when the engine runs.

  • Belt tension adjustment:Alternators usually have a link adjust bolt and support bolt. These two bolts can be loosened to adjust belt tension. Once the bolts are loosen, you can swing outboard your alternator as long as it is still attached to its support bolt. First, tighten the link adjust bolt and then the support bolt. You should tighten the belt enough that your thumb can push it down 12mm.
  • When they are not tightened enough, worn belts - alternator belts should be replaced. Keep at least one spare.
  • Charging Test: To test that the alternator charges correctly, use the instrument panel or digital voltmeter to check the charging status.

Alternator Problems

If the electricity within the alternator is not being used to charge a battery, it can cause rapid failure of electronic components. This could happen if the battery switch is not turned off while the engine is in use.

Alternators, like all parts, can wear down and become ineffective. To determine whether the issue is with the regulator, wiring or alternator, you will need to troubleshoot it.

  • Battery not charging: If the battery is not charging, it could indicate a problem with the wiring, the regulator, or the alternator.
  • If your batteries are not charging correctly, it could be due to a problem with the wiring or loose alternator belts.
  • Overcharging of batteries - This could indicate a problem with the battery or a defective regulator.
