If the coil is overheated it can easily short.
A short within the relay coil itself.
Different ways to induce current in a coil are as given below:(1) If a magnetic field is changed round a coil then an induced current is set up in the coil. It can be done by taking a bar magnet and bringing it closer to the coil or taking it away from the coil.(2) If a coil is moved in a magnetic field, then again an induced current is set up in the coil.(3) If a coil is rotated in a uniform magnetic field, it may also cause an induced current in the coil.(4) If we take two coils and insert them over a non conducting cylindrical roll then on changing current flowing in one coil, an induced current is obtained in the other coil.CommentYou don't induce a 'current' into a coil; you induce a voltage. If that coil is open circuited, then no current will flow. If, on the other hand, the coil is connected to a load, or its opposite ends short-circuited, then the induced voltage will cause a current to flow. Remember, current will only flow if there is a load, or short circuit, and the value of the current will depend upon the value of the induced voltage and the resistance of the load or short circuit.
If the current passing through a coil is too large, it can overheat and potentially damage the insulation around the wire, leading to a short circuit. This can cause the coil to fail and may pose a safety hazard.

That's an interesting problem i would test the coil, if that's not the problem i would check the wires for a short and high restance,
A broken coil spring will cause the effected corner of the vehicle to drop. A broken ignition coil will cause the engine to misfire (coil on plug application) or cease to run.
When an ignition coil goes bad the car will not run right, or not at all. An intermittent coil will cause shudder, or a jerking motion. When the coil has no output then the cylinder that the coil feeds cant burn the fuel and cause power.
Covering an electric oven coil with aluminum foil can obstruct airflow and cause the coil to overheat. This can lead to potential safety hazards such as short circuits, electrical fires, or damage to the oven. It is best to avoid covering the oven coil with any material to ensure safe and proper functioning of the appliance.
Maybe the coil is not good ?
Temperature can cause damage to the ignition coil. Temperature which is above 150 degrees Celsius can cause a great damage to it.
I would hazard a guess and say that it is a bad coil.
I have replaced the coil and distributor cap.
