The next chapter shows you how. The thought now is there wire from the K5 relay to the key has corrosion or is broken. Repairing broken leads, too. The starter relay is a small vehicle, and perhaps the reason why car owners often neglect it. When you start your engine and release the key or stop pressing the starter button on a modern vehicle, the circuit is supposed to close, which will discontinue power to the starter motor. Now, the starter motor used in most vehicles is a power-hungry device. Today, I go out to leave and the car won't start. A weak or dead battery can cause symptoms similar to those of a bad starter relay, and you want to rule that out. autoDisplay: false, It is one of the starter relay problems that need immediate attention. Use a wrench to remove the nuts that attach the leads to the posts on the relay. Iron core– the iron core magnetizes when the coil would around it is energized. Here is how. The cylinder types of starter relays feature connection posts. They include the following. However, the orientation or polarity does not matter as long as the relay does not use a diode. The manual will also help you find the relay if it’s location is not the one described here. Smart Car Wiring Diagram - Collections Of Wiring Diagram for Smart Car Best Ge Z Wave 3 Way Switch Wiring. Hot this week. Next, we look at how to fix starter relay problems. In the fender-mounted relays, this is the “I” terminal. If that does not happen, the reason could be a failing starter relay. Installing a new one is clearly worth the cost. If you have a fender-mounted starter relay, you will also need wrenches and sockets. Locate the relay. In some automotive applications, the starter relay works together with the starter solenoid to operate the starting system. The hard part when replacing this component is when shopping for one. If you cannot find the relay in your vehicle, consult its manual. That is because it can lead to damage of not only the relay but also other parts of the starting system. To test it, use the following procedure. Relay too old– starter relay failure does not need to have any identifiable cause. K2: Electric soft top. With the right tools and knowledge of what wire to connect to which terminal, the process to change a starter relay should be easy. new google.translate.TranslateElement({ In motor vehicles, a starter relay uses the small ignition switch current to close the much heavy-duty starter circuit. They are essentially a mechanical switch that is worked by an electromagnet. 99 A starter relay goes bad for various reasons. This is crucial not only because of size constraints, but also because an over- or under-sized starter could damage your Smarts motor. It closes contacts that switch on the starter motor. On one end of the core is an armature or plunger that closes contacts to work a switch. SMART ORIGINAL . SMART 450/452. It should indicate a small value to show circuit continuity. One of them is the starter relay, a small but crucial component of the starting system. That is because one of the small terminals of the relay is usually ground. Set the multimeter to read Ohms or resistance. Energize the primary side of the relay by completing the battery’s circuit and read the resistance. If that happens, nothing can possibly be fixed in most cases. Listen for any sound. The pins that register a high value should be the coil connections. A fender mounted starter relay has wires mounted on its connection posts. An old relay will have parts that are deteriorated to a point where they cannot work effectively. In that happens, we recommend that you use your car’s manual. But contrary to what some people think, the two names do not mean the same vehicle part. Fender-mounted starter relays are mostly the cylinder types. The contacts should be made of highly conductive and hard-wearing material, among other properties. There are many factors to consider, such as brand, starter relay price, and more. Installing a fuse box starter relay is a straightforward process. When starting a vehicle, different parts are involved. Starter relays that attach on the fender wall may not be difficult to find. If it does, check the cables and connections. The starter relay location may vary depending on the vehicle type and model. The starter relay prevents this from happening by allowing the starter current to bypass the ignition switch. The other end is where current enters the solenoid and contains the various connectors. The biggest threat to a starter relays lifespan is usually the contacts burning out. Order Starter Relay for your vehicle and pick it up in store—make your purchase, find a store near you, and get directions. Their identity is usually indicated on the cover of the fuse box. The relay switches a circuit that works the starter. Brand new battery fully charged, starter motor and solenoid works fine when connected direct to battery. These relays often have more than two connections for the primary side. Both the removal and mounting processes of the relay are different for the cylinder and box-like starter relays. No click. 0.6 (55CV) - Gasoline (from 01-2000 to 01-2004) 0.6 (61Cv) - Gasoline (from 01-2001 to 01-2004) In it, you will find all there is to know about the starter relay: what it is, its location in a vehicle, how it works, and its function. Contacts– these close the switch on the secondary circuit. Like most other motorized or powerful electric devices on your car, the starter doesn't draw its power directly from the switch used to trigger it. The ignition switch comprises delicate parts and very thin wires. } If the amount of current required by the motor were to pass through it, a lot of damage would occur. With the gap between the contacts of the starter circuit closed, the starter solenoid receives voltage from the battery and current flows through its coil windings. In fuse box starter relays, the ground is terminal 86. The wires and other parts of the switch would melt from the resulting heat- even vaporize. It means a relay that needs replacing. As it tries to close and open the contacts, you will hear a series of clicks. Corroded contacts–corroded contacts or connections cannot pass current in adequate amounts. Excessive heat– when too much current passes through the relay, it causes the contact to melt, leading them to stick together. Source:, The main parts of a typical starter relay include. You may also use a blower to remove dirt or microfiber cloth the clean the surfaces of the relay. layout: google.translate.TranslateElement.InlineLayout.SIMPLE The iron core becomes magnetized, causing the armature to move and close contacts. When you turn the ignition key to the “start” position or press the start button, the ignition circuit closes. Chapter 3: Symptoms of a Bad Starter Relay, Chapter 5: How to Replace a Starter Relay. It should not exceed 5 Ohms. When the engine has started, a reverse action is activated by the driver by turning off the ignition. Almost gone. Apart from starter relay buzzing or clicking sound, the engine may fail to start. SMART 450/452. Car is an Astra H 1.7 CDTI 2004. If it fails, check the wiring to ensure every cable is connected to the right terminal and that it is firmly attached. The two small terminals are the coil connections with one marked “S” and the other “I”. This symptom can show a starter relay is bad, but also a dead battery. Many people mistake the starter relay for the starter solenoid, thinking the two to mean the same thing. Replacing a starter relay is easy, and almost every vehicle owner can do it. The other big posts are the starter circuit terminals. Shop from the world's largest selection and best deals for Smart Car Electrical Relays.
