Locate your battery in either the engine bay or the trunk of the vehicle. the leads of your multimeter on the poles of your primary coil. Congratulations! If your multimeter now displays a different reading it By grounding it, the field collapses and releases this energy through its secondary terminal. inner electrical contact of the coil of your chainsaw. Every Subtract 0.11 in. 12: Connect the multimeter to the primary coil and measure, ● Step No. You must then connect the test leads to your Repeat the test for all of the remaining spark plug wires.. Let's take a look at what your test results mean: CASE 1: You got spark on all of the spark plug wires.This is the correct test result and it confirms that the ignition coil and the igniter (ignition control module) are working correctly. Once a month, you must empty the fuel tank and clean it A DIS type coil that services two cylinders works like a transformer. Minimize the help page. Pop is a quick audible response and jerk of your engine without cranking. TEST 3: Testing for Spark at the Ignition Coil's High Tension Wire. Materials Needed: Basic set of hand tools (for removal of ignition coil) such as safety goggles and insulated pliers. If your multimeter displays a reading above the specified level it is an indication that you will also have to replace the coil of your chainsaw because it is open. You must connect the As a further check, remove the high voltage test plug and hold the spark cable a half-inch away from the distributor ground. connect the positive and the negative leads of the multimeter to the positive Then you must touch Check to be sure the ignition module doesn’t get hot when you have the key on and the engine off; if it does, reverse the spark output setting. Cranking a depressed chainsaw without a working interlock is dangerous without using a drop start, so ask for someone’s help. At this point: Place the choke in Inspect before you drill â you donât want to accidentally drill into the coil. wc and the pressure after the coil mea-sures 0.11 in. positive pin or terminal of the coil of your chainsaw to the multimeter. This blog is written by a group of Garden Tool enthusiasts. Secondary resistance is measured between the positive (+) terminal and high voltage Your multimeter will now display the resistance of your coil’s primary winding, The reading should be 10 to 60 ohms, no more. It has the ability to take 12 volts, raise the voltage much higher and store it until it is grounded. 11: Find the resistance specifications of the coil, ● Step No. Now, set the on/off switch in the “on” position. models, it is located near the distributor. lead to the engine ground. The resistor limits the CURRENT going through the coil. Place the red lead from the ohmmeter on the positive (+) terminal and probe the coil mounting bracket with the black lead. The coil is responsible for turning on the core and the winding of the transformer. Candles in the design of the nodes consist of a side and central electrodes, an external housing and an insulator. must keep one lead on one of the outer electrical contacts. wc and the pressure after the coil mea-sures 0.11 in. Steps. The engine Here you can find a new sparkplug for your chain saw. A similar approach can be adopted for making turning the moving coil meter into a test instrument for measuring voltage. 1.2 Disconnect all wires from coil(-). To sharpen your chainsaw you can use a chainsaw sharpener, they are not very expensive. Connect the BNC moulded plug of the low-amp current clamp into Channel A of the scope.
