How do you tell which side of a coil is positive?
How do you tell which side of a coil is positive? When you hold the coil so the plug wires are to the left (like standard shovel or evo mounting, mounting holes at the rear), the negative side is on the top and the positive is on the bottom.
What side of the coil does the condenser go on?
The capacitor is connected to the positive terminal on the coil.
What is primary side of ignition coil?
The Primary circuit includes battery voltage (B+) terminal attached to a 12-volt current source and a ground (B-) terminal attached to a power transistor that controls primary current flow. To create a spark, the transistor is commanded by the PCM to form a magnetic field by grounding the primary coil.
How do you identify primary and secondary coil resistance?
Connect one terminal to the positive side of the coil, and the other terminal to the negative side. Take the reading from the meter. The reading should be between one and four ohms, depending on the type of coil and the vehicle from which it came. The higher energy the coil, the lower the primary resistance will be.
How many ohms Should a coil have?
Most coils should read between 0.4 and 2 ohms. Zero resistance would indicate a shorted coil while a high resistance reading would indicate an open coil.
What would cause a ignition coil to get hot?
Wear and tear is a common reason for ignition coils failing. It causes degrading of the insulation between the primary and secondary coil windings and the primary coil. The reduction in insulation can cause the coil to overheat. An ignition coil will get warm in use but it should not burn you or be too hot to touch.
How do you check a spark without a spark tester?
An alternative method to check if a spark plug is firing is to remove the spark plug from the engine. Plug the spark plug on your ignition coil. Ground the threaded part of the spark plug to the engine block. Crank the engine and see if you are noticing any spark at the spark plug tip.
