Milkman Posted April 18, 2019 Report Posted April 18, 2019 Unsure why won't start seems to have No spark also their is a random plug unsure what it goes in too Quote
altezzaclub Posted April 18, 2019 Report Posted April 18, 2019 (edited) Yeah, looks like there is a wire missing off the coil +ve. The ballast resistor drops 12V down to 9V for the 9V coil, but it gets bypassed when you're cranking. So the +ve coil side has two wires, one straight from the key for cranking, and one from the ballast resistor for running. Then the -ve goes to the dizzy, and to the tacho if you have one, and often to a capacitor to get rid of radio noise. Get a test light or a multimeter and find the wire that is +12v when the key is on cranking, it should be red, that goes on coil +ve. Check that the wire from the ballast to coil +ve is live when the key is just on ignition. Check where the coil -ve wires go to. You only need the one going to the distributor really. With the points open and the key on ignition, you should get a spark across the points with a screwdriver. There are wiring diagrams on here. See how you go... Oh, that purple wire just goes around the engine bay to the other side I think. Edited April 18, 2019 by altezzaclub Quote
