Ignition Coil Resistor Manufacturers Ignition Coil Resistor Suppliers Directory - Find a Ignition Coil Resistor Manufacturer and Supplier. Compatible Coils for Use with Hot-Spark Ignition. Applies to Hot-Spark 3-Series (red) ignition kits. Coil Warning: DO NOT use a low-resistance or an HEI-style coil. Before selecting a coil, check the coil primary resistance requirements as specified by the manufacturer of the ignition being used. This testing procedure is valid for most automotive coils. Using an ohmmeter, check the resistance between the side terminals of the coil. Ignition coil resistance questions Modular V8 (4.6L, 5.4L) I have no. 4 and 5 plugs misfiring. How to test an ignition coil This testing procedure is valid for just about any automotive coil. Ohms is a unit of measure for the resistance that a wire or coil has.
