I was hoping someone could help me with a problem I have with my 1994 Mercury 40hp 4 cylinder 2 stroke. The motor ran great to the fishing hole, then would not start to come back, towed back in. I have no spark on my plugs, used an inline spark checker, nothing on any four plugs. I have a CDI Stator, Trigger, Voltage Reg, and Switch Box, used their manual to trouble shot and hit a dead end when it came to the yellow/black kill wire. Using the DC scale on DVM I get 0.006 volt when I switch the key on and off, but a full 12volt when I am turning the motor over. Took this reading at the bullet connector beside the starter solenoid, separated the connector and connected to side that is connected to the switch box. With the wire disconnected I still "did not" have spark on my plugs, but I wondered about reading voltage while the motor is cranking over. Does this sound correct, what should I try next?
Thanks for the help
