I was just reading up on it, and the Hot Spark web site says:
Quote: If the charging system voltage, measured at the coil's + terminal, is more than 14.0 volts at any RPM level ... [a] ballast resistor should be wired between the coil's + terminal and the red HotSpark ignition wire. Too much voltage can damage the ignition module ![Open in new window](javascript:CaricaFoto("http://datsun1200.com/uploads/photos/24525.jpg");) Internally regulated alternator is a little tighter on specs, but still goes over 14.0 volts. By the way this is for most all cars, even new cars, as they use the same lead-acid battery chemistry There is no red X, these are the two "options": * wire up ballast resistor in between IGN and COIL + * no ballast resistor wired up between IGN and COIL + For racing w/o an alternator, the "optional" no-ballast would work fine. Otherwise use the stock 1200 wiring (with ballast wired up) ![Open in new window](javascript:CaricaFoto("http://i297.photobucket.com/albums/mm219/ddgonzal/Datsun+1200/engine/E-Series/Distributor/WiringDiagram.jpg");) Attach file:  WiringDiagram.jpg (35.14 KB)
