No it won't.Inside the coil are a lot of copper wires all insulated from each other.

If this insulation fails and the wires inside touch...the coil stops working.

The coil can be detached and tested using a ohmmeter. The leads are placed on the outside prongs of the coil, and the resistance is tested. The coil should show a resistance somewhere between 0.75 and 0.85 ohms.

What are the symptoms of defective coil?

A defective coil can cause an engine to run erratically or not start at all. Coils can weaken, causing insufficient spark. A coil can also breakdown once it heats up then work when it gets cooled down.

This is not true. If it gets too hot, it will shut down, but will not break unless you keep pushing the button or something to break it.

Usually when an engine overheats the distributor is the least of your worries. An overheated engine could potentially melt itself into a 300 pound chunk of scrap metal if it gets hot enough.

Why is there yellow goo on your oil cap?

You either have a cracked head gasket or your engine is not running hot enough on many short trips. Either way, it's a problem and it needs to be looked at. The goo also gets down into your engine and will eventually cause it to break down. Change your oil often to keep it from building up in the engine.


What causes a 17 hp engine to stop running when it gets hot?

More than likely the coil is breaking down and needs to be replaced. The other things that could cause this is that there may be debris under the engine cover that is keeping the cooling fins from blowing air accross the cylinder head. This will make the engine get hotter than normal and shut it down. If you remove the metal engine cover it should be obvious if this is the problem.


What do mitochondria break down?

Glucose, a type of sugar, initially gets broken down via glycolysis in the cytosol into pyruvate molecules. Mitochondria then break down the pyruvate extracting the electrons from them. The simple answer though is that mitochondria break down a sugar called glucose.
