How to judge the ignition coil

Core tip: ignition coil removed later, first with a multimeter to measure resistance. Primary resistance is generally a few ohms, big for open circuit, 0. Subprime 5 ohm below is electrode short circuit, namely the high tension line end to any junior has thousands of ohm resistance between specific models.

Can also use wire cut two primary short time to touch the electric shock bottle of two electrodes, touch when there is no distinction between positive and negative, disconnect the instant high tension line end to any one primary line end should be weak cremation occurs is normal ( High tension line end to the primary line end keep about 2 mm gap] , no burnt out general often burn ignition coil has two reasons: 1. Coil quality is bad. Ignition module quality is bad
