okay, so I know that L-jet uses the point pulses to fire injectors...my main relay is working, so what connections do i need at the coil?
i already have the tach wire, the point wire at the neg and nothing at the positive.... but i have a brown wire and two black wires joined to one both sets of wires having 12VDC on them....what gives? b |

so, with a test light.
mount one side of test light to positive side of coil mount the other side to ground. Key to on position. if light works you have power to the coil. I know you did this with the multi meter...just do it with a light to both test the light and double check your readings...you may read 12v, but if the light is dim, you dont have enough amps... Points/condensor testing now take the test light lead that is connected to the positive side of the coil and move it to the negative side of the coil remove the HD coil wire to the dizzy cap remove cap and turn motor by hand. the light should light up every time the points open.. test all four dizzy cam lobes to make sure you have no short in the dizzy. if that is not the case, if the light does not light , and the points are clean and there is no crap in them, you need a condensor. you can confirm the condesor test by putting the test light inline. Unplug the green wire going to the negative side of the coil. put the test light in that circuit and turn the motor over by hand with the key on. the light should light, if not, you have a bad condensor. Coil testing. Put everything back together,,, rotor and all. (please tell me that you have a rotor...I have forgotten that more than once...) Pull the coil wire from the center of the distributor cap. hold the coil wire 1/8 inch away from a good ground. this is the leather glove part (it does hurt) turn motor by hand if spark is blue/blue white/white you have a good coil If spark is yellow and strong, you will need a new coil, but it will work for now If spark is weak, or no spark, you need a new coil.
