I have a 1977 75 Johnson. I have replaced the rect. 3 coils, power pack and switch. Motor will not start with the new coils, put old one's back on it runs fine. The problem is the flywheel gets very, very hot. I do not have a volt gauge, but I think the stator is putting out to much voltage. I.E. the new ign. switch is now shorted on the kill wire just like the first. Adle 303 volts on rect. wires, 293 on sensor wires, 93 on brown and brown orange wires to power pack. Note new coils read 304 ohms between trigger and plug wire, old one's are open.
