This means whatever voltage that enters the primary coil is multiplied by 100 times in the secondary coil for external uses.<\/div>\n<\/div>\n<\/div>\n<div>\n<div id='gallery-4' class='gallery galleryid-13 gallery-columns-2 gallery-size-thumbnail'><figure class='gallery-item'>\n\t\t\t<div class='gallery-icon portrait'>\n\t\t\t\t<a href='https:\/\/commons.princeton.edu\/59-tiger-cub\/wp-content\/uploads\/sites\/79\/2018\/08\/IMAG0490.png'><img loading=\"lazy\" decoding=\"async\" width=\"150\" height=\"150\" src=\"https:\/\/commons.princeton.edu\/59-tiger-cub\/wp-content\/uploads\/sites\/79\/2018\/08\/IMAG0490-150x150.png\" class=\"attachment-thumbnail size-thumbnail\" alt=\"\" aria-describedby=\"gallery-4-326\" \/><\/a>\n\t\t\t<\/div>\n\t\t\t\t<figcaption class='wp-caption-text gallery-caption' id='gallery-4-326'>\n\t\t\t\tIgnition Coil\n\t\t\t\t<\/figcaption><\/figure><figure class='gallery-item'>\n\t\t\t<div class='gallery-icon portrait'>\n\t\t\t\t<a href='https:\/\/commons.princeton.edu\/59-tiger-cub\/wp-content\/uploads\/sites\/79\/2018\/08\/ignition-system-coil.gif'><img loading=\"lazy\" decoding=\"async\" width=\"150\" height=\"150\" src=\"https:\/\/commons.princeton.edu\/59-tiger-cub\/wp-content\/uploads\/sites\/79\/2018\/08\/ignition-system-coil-150x150.gif\" class=\"attachment-thumbnail size-thumbnail\" alt=\"\" aria-describedby=\"gallery-4-327\" \/><\/a>\n\t\t\t<\/div>\n\t\t\t\t<figcaption class='wp-caption-text gallery-caption' id='gallery-4-327'>\n\t\t\t\tInside of Coil (http:\/\/auto.howstuffworks.com\/ignition-system3.htm)\n\t\t\t\t<\/figcaption><\/figure>\n\t\t<\/div>\n\n<h3>Spark Plug<\/h3>\n<div class=\"left\">\n<div class=\"row\">\n<div class=\"cell\">The spark plug is what ignites the air-fuel mixture in the engine to start the motorcycle. To do this, the spark plug requires a very high voltage (provided by the coil) to force the electrical current to jump across a gap. It also has a porcelain insulator to ensure that the spark happens at the tip.<\/div>\n<div>\n<div id='gallery-5' class='gallery galleryid-13 gallery-columns-1 gallery-size-thumbnail'><figure class='gallery-item'>\n\t\t\t<div class='gallery-icon landscape'>\n\t\t\t\t<a href='https:\/\/commons.princeton.edu\/59-tiger-cub\/wp-content\/uploads\/sites\/79\/2018\/08\/IMAG0487.png'><img loading=\"lazy\" decoding=\"async\" width=\"150\" height=\"150\" src=\"https:\/\/commons.princeton.edu\/59-tiger-cub\/wp-content\/uploads\/sites\/79\/2018\/08\/IMAG0487-150x150.png\" class=\"attachment-thumbnail size-thumbnail\" alt=\"\" aria-describedby=\"gallery-5-328\" \/><\/a>\n\t\t\t<\/div>\n\t\t\t\t<figcaption class='wp-caption-text gallery-caption' id='gallery-5-328'>\n\t\t\t\tSpark Plug\n\t\t\t\t<\/figcaption><\/figure>\n\t\t<\/div>\n\n<h3>Distributor<\/h3>\n<div class=\"left\">\n<div class=\"row\">\n<div class=\"cell\">The distributor is a very important part as it contains the cam, the condenser, and the contact points. As the distributor cam rotates with the engine, the points are pushed apart at specific timings to break the electrical circuit, which eventually causes the spark in the spark plug. The condenser stores current and discharges it as part of the electrical circuit. We measured the condenser to be 265.7 nF.<\/div>\n<div>\n<div id='gallery-6' class='gallery galleryid-13 gallery-columns-2 gallery-size-thumbnail'><figure class='gallery-item'>\n\t\t\t<div class='gallery-icon portrait'>\n\t\t\t\t<a href='https:\/\/commons.princeton.edu\/59-tiger-cub\/wp-content\/uploads\/sites\/79\/2018\/08\/IMAG0489.png'><img loading=\"lazy\" decoding=\"async\" width=\"150\" height=\"150\" src=\"https:\/\/commons.princeton.edu\/59-tiger-cub\/wp-content\/uploads\/sites\/79\/2018\/08\/IMAG0489-150x150.png\" class=\"attachment-thumbnail size-thumbnail\" alt=\"\" aria-describedby=\"gallery-6-330\" \/><\/a>\n\t\t\t<\/div>\n\t\t\t\t<figcaption class='wp-caption-text gallery-caption' id='gallery-6-330'>\n\t\t\t\tDistributor\n\t\t\t\t<\/figcaption><\/figure><figure class='gallery-item'>\n\t\t\t<div class='gallery-icon portrait'>\n\t\t\t\t<a href='https:\/\/commons.princeton.edu\/59-tiger-cub\/wp-content\/uploads\/sites\/79\/2018\/08\/IMAG0493.png'><img loading=\"lazy\" decoding=\"async\" width=\"150\" height=\"150\" src=\"https:\/\/commons.princeton.edu\/59-tiger-cub\/wp-content\/uploads\/sites\/79\/2018\/08\/IMAG0493-150x150.png\" class=\"attachment-thumbnail size-thumbnail\" alt=\"\" aria-describedby=\"gallery-6-329\" \/><\/a>\n\t\t\t<\/div>\n\t\t\t\t<figcaption class='wp-caption-text gallery-caption' id='gallery-6-329'>\n\t\t\t\tInside of Distributor\n\t\t\t\t<\/figcaption><\/figure>\n\t\t<\/div>\n\n<div class=\"picture-component\">\n<h3>Wiring Harness<\/h3>\n<div class=\"left\">\n<div class=\"row\">\n<div class=\"cell\">The wiring harness connects all the wires and allows electricity to flow throughout the bike&#8217;s electrical units. We were able to use a pre-made wiring harness as a template. We still had to make extra wires, using soldering techniques to connect separate wire tips. We also had to make sure there was electrical contact on the frame to ensure proper grounding of the entire electrical circuit. This consisted of scraping paint away from from the frame so that there is metal to metal contact.<\/div>\n<\/div>\n<div><img loading=\"lazy\" decoding=\"async\" class=\"alignnone  wp-image-331\" src=\"http:\/\/commons.princeton.edu\/59-tiger-cub\/wp-content\/uploads\/sites\/79\/2018\/08\/IMAG0482-1.png\" alt=\"\" width=\"929\" height=\"523\" srcset=\"https:\/\/commons.princeton.edu\/59-tiger-cub\/wp-content\/uploads\/sites\/79\/2018\/08\/IMAG0482-1.png 460w, https:\/\/commons.princeton.edu\/59-tiger-cub\/wp-content\/uploads\/sites\/79\/2018\/08\/IMAG0482-1-300x169.png 300w\" sizes=\"auto, (max-width: 709px) 85vw, (max-width: 909px) 67vw, (max-width: 1362px) 62vw, 840px\" \/><\/div>\n<\/div>\n<div class=\"clear\"><\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Alternator Rotor and Stator The alternator generates AC current to charge the battery and power the bike&#8217;s electrical units.
