For many years, mainland Western Europe has used a mains electricity supply rated at nominally 220VAC 50Hz while the UK used 240VAC 50Hz. In 1994, the European Union state members decided to proceed with a voltage harmonisation at 230Vac. This meant that consumers could be sure that a produc...
If your lawn mower won't start, the problem may be that the spark plug isn't firing. Sometimes, all you have to do is replace the plug, but if you've done that, and you've taken care of fuel and air circulation issues, it's a good idea to check the ignition coil for continuity...

Also check for discontinuity between N/C contacts and pole. As a final test, measure the resistance of the relay coil using a multimeter and check whether it is matching to the value stated by the manufacturer. If all the above tests are positive we can conclude that the relay is healthy....
When a relay is used to switch a large amount of electrical power through its contacts, it is designated by a special name: contactor. Contactors typically have multiple contacts, and those contacts are usually (but not always) normally-open, so that power to the load is shut off when the...
4. According to the technical requirements, regularly check whether the wiring of each electric furnace and controller is good, whether there is any stuck stuck phenomenon when the indicator pointer moves, and use the potentiometer to check the instrument due to magnetic steel, demagnetization, wire...
Check the capacitor is charge/discharge. Locate the digital multimeter on 1k. Connect the leads of this meter to the terminals of a capacitor. This meter will display some numbers, please note down. After that, it will come back to the Open Line. Every time it will show the same result...
Disconnect supply to motor control ( Main switch OFF )Replace fuse(s) if there is blown one(s), reset overcurrent relay2. check all motor contactors -wiring connections are tight -when closing contactor by pushing with hand -- all contacts closes and closed resistance is zer...
The most widely used overload relay is the thermal overload relay where a bimetallic strip is used to turn off the motor. This strip is set to make contact with a contactor by bending itself with rising temperatures due to excess current flow. The contact between the strip and the contactor...
