rags Posted February 28, 2001 Share Posted February 28, 2001 Can someone tell me which wire is feeding the ignition resistor that is next to the coil on a 71 240? The wire colors are Black w/white stripe and green w/black stripe. I want to use the feed for a switched 12 volt source for the TEC II and I can't test it because the harness is on my kitchen table! A quick response is greatly appreciated by my wife. Joe Quote Link to comment Share on other sites More sharing options...
Kevin Shasteen Posted February 28, 2001 Share Posted February 28, 2001 Joe, What better place to "Soup" up parts of your car than the Kitchen? Tell your wife as per the JTR manual: The Black - white wire with the protective sleeve is connected to the ballast resistor, and the Green - white wire is connected to the other side of the ballast resistor while the "OTHER" Black - white wire "W/OUT" the protective sleeve is connected to the positive (+) side of the ignition coil. JTR manual doesnt mention a "Green -Black stripe wire....I'm sure its the same as the "Green - white wire". JTR manual says if your ignition/tach doesnt work then just switch the wires around & that is usually all that's needed to get the tach working. It does have one other reference. It says the Sensing wire on the 240Z is a whire wire that does a loop on the back of the tachometer; comes from the ballast resistor & goes to the positive (+) side of the ignition coil. Sorry-that is all it says. I have a 78 280Z so mine will be a little different. Maybe someone w/a 240Z can respond & confirm the info I gave. Hope that helps keep you out of the Doghouse!
