i have a 78 johnson 70hp. on the power pack the three coil wires wires go in line 1 2 3. when i have all three connected only 1 will spark. if i disconnect 1 numbers 2 and 3 will spark. ive double checked all my connections and grounds to make sure nothing was crossed. can any one please let me know what im missing. im guessing which i really really dont like to do but im stuck that its a bad power pack but its $100 for a guess. is there anything else i can do to verify the problem. thank you in advance for any info.
