Ignition coils are made up of two coils of wire situated on top of each other. at 3,000rpm °BTDC 37 at 8,000rpm °BTDC 37 . PET-9000 Parameter #1 357 #2 07 . Use of any coil that is not compatible may damage the MSD and void the warranty. The winding ratio of primary to secondary winding is 1:100. The primary winding gets the juice together to make a spark and the secondary sends it out the door to the distributor. Primary coil resistance Ω 160 - 200 . You can test the resistance of the coil using a voltmeter and measure the Ohms (resistance) across the +’ve and –’ve terminals. These coils are called windings. Also, mount the coil so the coil wire is as short as possible to keep resistance low. In this test, you pass a small electric current through the wire and measure resistance with an ohmmeter. The Ohmic resistance of the coil is about 0.2-3.0 Ohm primary and 5-20 kOhm secon-dary. Pole shoe air gaps mm(in) 0.30 - 0.40 (0.012 - 0.016) Ignition timing at 1,000rpm °BTDC 34 . If the spark plug ignition cables are getting faulty, it will have a much higher than normal resistance which causes additional voltage to be generated by the ignition coil … Typically, the ignition coil can go bad over time due to either long-term wear and tear or due to bad spark plug ignition cables. Moss Motors Tech department shows you how to test your coils Ohm rating. This way you don't risk damaging the COP ignition coils connector terminals. All of the circuits can be tested without having to unplug the Coil-On-Plug ignition coil. The Makeup of the Coil . Carburetor The low resistance helps to produce up to 45,000 V. Circuit Descriptions Of The C-O-P Ignition Coil Connector. One winding is the primary winding, the other is the secondary. Secondary coil resistance kΩ 1.2 - 1.8 . These are gener - ally found on late model DIS or coil-per-cylinder ignitions. A standard coil should read around 3 Ohms or around 12 volts Caution: Coils that have an internal power transistor are NOT compatible with MSD Ignition Controls. In this case, the following method is helpful: Connect a voltmeter in series between the secondary winding of the ignition coil and a battery. Flame Thrower II coils have lower resistance, 0.6 ohms for use with Ignitor II ignition systems as well as many other high-energy ignitions. If a spark plug or plug wire is open or has excessive resistance, the ignition coil's output voltage can rise to the point where it burns through the coil's internal insulation causing a short. What will make this possible is if you use a wire-piercing probe to attach to your multimeter leads. In the case of a conventional cylinder ignition coil, … The insulation in many coils can be damaged if output exceeds 35,000 volts. The technical structure can vary, depending on the ignition coil‘s area of application. To find out for sure, use a multimeter to check the voltage on the positive wire of the coil with the ignition on. Note: If a high-voltage diode is built into an ignition coil to suppress sparks, it is not possible to measure the resistance of the secondary coil. If the coil is intact, the resistance is a measurable number in the order of 2,500 to 5,000 ohms. It's impractical to uncover the coil and examine the wire; fortunately, there's an easier way to find a break -- a continuity test.
