Re: mercury 4.5hp 1980-location of white wire?
Lets try one more time, look at the the wiring diagram, The 2 charging winding hook on the ign module at the other end of the module where 1 end of each goes to the outside screws and they are bonded together at the middle screw, which goes through a diode in the module and sends voltage to the outside terminal at the other end where the capacitor and green coil wire are attached. At the end that you are having a problem with there is 1 black wire going from ground to the inside terminal of the ign. module. The green wire from the capacitor goes to the outside terminal of the ign module where it joins the other green wire that to the coil. That leave the white wire from the coil it goes to the point stud. Any other way won't work if there are other wires get rid of them, with the exception of the wire from the kill switch usually orange and it hooks to the same terminal on the coil that the white wire is fastened to if the engine is so equipped.
