I have a 86 Mariner, 75 HP, 4 cylinder. No fire to 1 & 2 cylinders. Did all the checks. REPLACED SWITCH BOX. Hooked up all wires except the black with yellow stripe (kill circuit, I think). I have .01 volts on this wire (yellow with black stripe) when key switch is in run position. Zero in off or start position. Is this normal or do I have a switch/wireing problem? I do have fire to all cylinders now but have not tried to start it. Sure would appreciate any thoughts, coments, or expert advice.
