Ignition System Diagnostics and Repair

Go Kart Engine Diagnostics: Solid State Ignition Failure Detection

I even have had multiple instances in which I had a few dramatic screw ups arise on my move kart engines. One time I had a sequence snap and the chain made a ferocious clunk after which fell off the pass kart. The funny thing is that the engine kept strolling, and I had to close it off.

I replaced the chain and ran into a weird trouble. The engine might no longer begin.

This is wherein maximum of us, with NO engine experience simply throw up our fingers and kick the pass kart and go away. Then we throw it in the back of the pickup and bring it over to “Smokin Joes Lawnmower Repair.” There we spend about $2 hundred to have the engine constant.

I am here to inform you forget approximately going to “Smokin Joes.

First of all a simple knowledge of ignition systems is needed. (I am assuming which you apprehend the Otto Cycle or four cycle engine principle, so I will dispense with that SnoozeVille clarification)

Ignition systems are basically partial turbines. The flywheel has a magnet, and the Magneto has a coil of wire in it.

The principle behind electric current is that after a wire (a simple twine ) is handed thru a magnetic area that an electric current is brought on into the wire.

And conversely, whilst a cord is prompted with an electric current it gives off a magnetic area.

The Magneto (the tool that the spark plug cord comes out of) has a coil of wire in it plus a center of iron to attract or listen the magnetic flux lines into the twine.

The cord then gets an instantaneous leap in power as the magnetic field within the flywheel passes by it. The unexpected increase in power is focused as excessive voltage which is released as a spark within the spark plug.

The timing, or the firing of the electricity to the spark plug is regulated by way of circuitry. This particular circuitry is activated by means of a small magnetic sensing transfer (which seems like a small cylinder of steel tucked in with the coil). When the magnet passes by way of the magnetic field turns on the transfer. The switch then releases the coil strength into the spark plug.

The spark plug is nothing greater than a glorified leaping bridge for energy. We all are acquainted with this static discharge while we scrub our toes against the ground and the attain out and touch anyone. A spark jumps when we get close, like .125 inches and nearer.

The design of the spark plug is to hold the strength remoted up to the bridge. Once the electricity from in the back of shoves real tough, it forces the electrons in front to jump. Kind of like getting pushed off of a bridge.

So the white a part of the spark plug is non-conductive and an insulator. The metal element is isolated from the rest of the spark plug and most effective becomes integral while spark completes the circuit or jumps throughout the space
