<p class="MsoNormal"><span style="font-family:"Arial","sans-serif"">By way of recap: When the points close current flows through the primary (12 volt) side of the coil. When they open the magnetic field around the coil collapses across the secondary coil
windings (high voltage) driving a high voltage current across the plug gap and firing the cylinder. At the same time the magnetic field also across the primary windings attempting to drive a current across the open points and creating a relatively high voltage
(perhaps 400 volts) which will want to arc across the open points and wearing them out quickly. To mitigate this a condenser (capacitor) is places between the points coil connection and ground which absorbs the “shock” of the current being driven towards
the open points and reducing the potential for arcing across the points allowing them to last longer.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial","sans-serif""><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial","sans-serif"">Question: Why would a larger condenser (capacitor) not reduce the potential for arcing across the points even more? What might be the down side of such an attempt???<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">I drive my car on multi-day cross-country trips and see the value in installing a modern alternator. The generators on our cars were installed 50 years ago,
and designed way before that to provide a fairly modest output [~20 amps, if memory serves]. The generator was barely able to supply the car’s needs as supplied, and modern use calls for additional and more power-hungry apliances in the car, such as headlights
that actually light up the road ahead…<o:p></o:p></span></p>

if it happens to fail, rebuild or repar are readily available. Note that none of this drives me necessiarily to any other modifications.<o:p></o:p></span></p>

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">So, when I was doing the job, I looked at pictures of other people’s installations. Nobody’s coil was mounted on the alternator as coils were/are mounted on the generators.<o:p></o:p></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">I didn’t mount mine on the alternator either.<o:p></o:p></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">Now, I’m wondering why everybody found ingenious places to put the coils and nobody ingeniously adapted their brackets to fit onto their alternator.<o:p></o:p></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">Do alternators get too hot? Do they give off some kind of magic death ray that fries coils or what??<o:p></o:p></p>
