If current is going to the distributor points but not to the spark plugs, what could be the issue?

When current reaches the distributor points but fails to reach the spark plugs, one likely issue could be a defective rotor arm. The rotor arm plays a crucial role in directing the electrical current from the ignition coil to the proper spark plug at the right timing. If the rotor arm is defective or damaged, it may not properly transfer the electrical charge, leading to a lack of spark at the plugs.

The effectiveness of the ignition system relies heavily on the rotor functioning correctly. If it cannot make the necessary connections or is not aligned properly, the ignition system will fail to ignite the air-fuel mixture in the engine.

Other potential issues, such as a defective ignition coil, a blown fuse, or a faulty battery, could also affect the overall performance of the ignition system. However, these scenarios would typically result in no current reaching the distributor points at all, rather than just an interruption in the path from the distributor to the spark plugs. This distinction reinforces why a defective rotor arm is the most likely culprit in this situation.
