Most coils should read between 0. How is it measured? Set the multimeter to measure resistance ( ohms ). Connect the positive lead to the positive terminal of the coil. Learn the signs of bad ignition coils and how to test the coils yourself with.
Place one test lead from the ohms meter on the negative post and one on the positive post of the coil.
PerTronix Ignitors . Primary coil resistance hook up lead of the multimeter to the electrical tab and the other lead to the iron core. Measuring ignition coil resistance was once a popular test method. Then, an electronic control unit for the charging of the ignition coil took the place of breaker points, which by then were a technology that was three-quarters-of-a-.
For the type of coil found in the GX1- GX1Honda engines, the primary resistance value should be in the region of 0. A “standard” coil will have an internal resistance close to ohms on its primary windings. Bosch coils are made in a number of countries, with varying amounts of primary . Therefore, never measure the resistance. A working ignition coil will give a reading of between 2.
