Does anyone have a 240Z with stock ignition that could take some voltage readings. I am having trouble getting my car to start. With the key in the on position the ballast resistor for the coil gets real hot. If I take the +/- coil wires off and check voltage I get about 12 V. When I turn the key to the start position the voltage drops to 8-9 V. Is'nt this backwords from what it should do. I thought you get the full battery voltage just during starting and then it should drop ot-8-9V after starting. The car will start for a short time and then start running real erratic and then die. I have changed points, condenser, coil, rotor, dist. cap wires, voltage requlator, checked timing. Has anyone else experienced anything like this. I was out driving one day and all the sudden it backfired and then died and now I can't get it to run again.
