To test the operation of both the ignition coil and the spark plug, connect the tester between the spark plug boot and the spark plug. Set the points too wide and the spark plugs don't get enough juice. You'll need these resistance specifications to compare them to your own test results. A. In these applications, the coil is built into the plug and into a singular tube to make a space-friendly plug. While you are at it, try wiggling the cables around with the voltmeter probes firmly attached. Crank the engine, just enough to inspect the condition of the spark. Be sure to wear splash-proof goggles. An ignition coil is an electromagnetic induction-type transformer that turns low electrical voltage from the battery into high voltage provided to the spark plug, which then sparks and ignites the air and fuel mixture inside the engines combustion chamber. Step 3: Disconnect the wiring harness for the ignition coils. If it still isn't right, try again. The points have a spring clip that acts to hold the points shut, and this spring causes the moveable point to snap back into contact with the stationary point mounted to the distributor plate when the cam rotates out of contact. If it's bad, you'll get a weak spark or no spark at all. Just treat them as individual points when setting them up and you'll be fine. Resistor on Mercruiser replaces 898253T24. Connect one lead of your ohm meter to the nut where the condenser and coil are connect to the points and the other lead to ground. If the battery needs to be recharged make sure to use a trickle charger, a charger that runs at no more than 2 amps. Ignition coils are made up of two coils of wire situated on top of each other. Testing a coil-on-plug (COP) type ignition coil is similar to testing other ignition coils. Much cheaper than a coil! Detach the air inlet tube from the throttle body. Some engines have an external resistor near the ignition coil. Then start the engine and watch the tester window. The changing voltage in the primary winding serves as the 'movement' needed to induce a voltage in the secondary winding. By using our site, you agree to our. If not, check the ignition switch or that side of the circuit or, in some applications, the crankshaft position sensor. The easiest and best method to pinpoint a problem on these coils is to do the #1 method of swapping the coil with a neighboring coil to see if the misfire moves to a different cylinder. Once you have them out, install the new ones but don't tighten the points completely, just snug them up. When the points close, the current through the coil primary increases from zero to maximum in an exponential manner, rapidly at first, then slowing as the current reaches its maximum value. I had the car towed to a friend's house (I was 800 miles from home) and set about diagnosing the car. Any spark plugs wires with cracked insulation should be replaced.
