How can you measure the effectiveness of an ignition coil?
If you have access to a piece of electrical equipment called an ohmmeter, which measures electrical resistance, you can measure the effectiveness of your ignition coil in a definitive, quantifiable way, rather than in the somewhat subjective way described above.
How are the coils set on a car?
Most commonly these run lengthwise, but there are transverse variants as well; in either case they may be lined with wood or other material to cushion the load. The coils are set on their sides in the trough, and stops may be applied across the trough to keep the coils from shifting.
Where are the electrical contacts on an ignition coil?
Position the leads of the ohmmeter on the poles of the primary coil. The distributor will have three electrical contacts – two on either side and one in the middle. These may be either external (jutting out) or internal (sunken in) – it makes no difference.
When was the first railroad coil car made?
Load shifting, damage, and awkward loading and unloading were all problems, and since so much sheet steel is transported, a specialized car was designed for this use. These cars started to appear in the 1960s. Early examples include the Pennsylvania Railroad G40 and G41 class cars, built in 1964-65.

How does a crankshaft position sensor work on a car?
From the get-go, all but the most primitive EFI systems employed a crankshaft position sensor, also called a crank angle sensor (abbreviated as either CPS or CKP), to tell the car’s electronic control unit (ECU) where the engine is in its rotation cycle, so it knows when to fire the fuel injectors and time the spark.
What should the resistance be on a Delco ignition coil?
This reading of 8.84 does indicate that the coil’s secondary windings are not putting out as much voltage as they should; the minimum acceptable resistance reading here should be 11.00, with approximately 13.5 being normal. Here’s the primary reading on the new replacement GM Delco coil before I installed it.
