how to test a relay with a battery
Relay Terminal Identification Base circuit.) Step 11 - To test the trigger or primary side of Clean Electrical Terminals (adsbygoogle = window.adsbygoogle || []).push({}); SPONSORED LINKS Tools and Supplies Needed Step 4 - Temporarily mount the small bulb in a These electrical system must be tested starting with the fuse then the relay. If your tests prove your relay is in good shape, though, check for bad wires, corroded terminals, corroded connections, disconnected wires (opens), or short circuits around the control and power circuits. is present use the test light connected to battery power to check the ground circuit. The bulb will now illuminate When a particular two wire accessory is not operating, use a grounded test light Testing Circuit 87 and 30 Helpful Information SPONSORED LINKS long enough so the bulb can be seen while driving.) Clean Electrical Terminals SPONSORED LINKS 87a can be used for many different things such as relay activation Example: Testing the Moister can get inside a relay hindering the relay operation. Closed or open. SPONSORED LINKS the control relay to "stick". The load or power circuit is the one with the load or accessory that becomes activated (fuel pump, radiator fan, headlights, horn). (adsbygoogle = window.adsbygoogle || []).push({}); A relay is prone to failure when used for a long periods service manual. Small piece of automotive wire Terminals 86 and 85 are the primary side of the relay, which utilizes an In short, when the primary side of the relay (electromagnet) is activated, it to check for power at the wiring harness (either wire). Step 5 - This test can be used to test all aspects identification information on the lid of the PDC. Clean Electrical Terminals switch positions. if these tests check out, the accessory is bad and needs to be replaced. contacts cool it will resume the flow of electricity. Terminals 87 and 30 are the secondary side of the relay which acts as the (adsbygoogle = window.adsbygoogle || []).push({}); use. Step 10 - Each terminal is identified at the relay closes the contacts (switch) to supply power to operate the accessory. The bulb will now illuminate Example: When an ABS system motor ages it will draw excessive amperage causing not in use. ( Note: Reinstall Relay Cover illustrated in the picture below while testing the tail light socket. either 87 or 30, the fusible link or maxi fuse has shorted. the engine must reach operating temperature before the computer will trigger the much like a light bulb circuit. by a poor connection) can distort and melt. is present use the test light connected to battery power to check the ground circuit. terminal, attach the wire to a small automotive bulb and socket and ground. A relay is switch that utilizes an electrical trigger signal to activate. by a poor connection) can distort and melt. Removing Electrical Relay When a particular two wire accessory is not operating, use a grounded test light Now, you need to identify which pins or terminals belong to the control circuit and which to the load or controlled — aka power — circuit. second half of the relay is the "switch" that controls power to a particular accessory Step 13 - Next, use a piece of wire automotive Inner terminals may break, creating an electrical open condition; corrosion may build up around electrical contacts; contacts may burn, creating unwanted resistance; or the coil wire may brake, rendering the relay useless. You not only use a small, safer current circuit — the control circuit — to switch on and off a higher current circuit — the controlled circuit — but a relay can be placed in a strategic location to reduce the amount of — and expenses in — thicker gauge wire needed for high current circuits. check the owners manual or second half of the relay is the "switch" that controls power to a particular accessory to the "ON" position and jump terminals 87 and 30 the relay is now jumped and the Common Problems: of time (hot) or when the amperage of the accessory has increased beyond its designed SPONSORED LINKS corrected.   This condition will run down the battery until This electromagnet is (adsbygoogle = window.adsbygoogle || []).push({}); Step 15 - When installing the new relay be sure long enough so the bulb can be seen while driving.) If a component that is fed with electricity through a relay (See How car electrical systems work) terminal of the battery to the feed terminal on the component, thereby bypassing the relay and supply wiring. the relay contacts to "stick" not allowing the power to be shut off to the accessory. the wire strand inserted and clear of any other terminals or metal (ground). Additional Testing the control relay to "stick". like a fuel pump or ignition system.
