Debe,
You were right about the voltage spikes. The DIP102s fried today on me I was trying them on a 33hp Johnson 1965 with purple coils. The small wires on the coil didn’t need to be switched to produce fire which was a good thing I just screwed them in and bam I had fire until I started engine then they died. On that particular motor it does have they 2 wires that go to points that when connected together kill the motor. I attached 2 modules with BD649s outside the flywheel using alligator clip jumper wires and the spark returned even with the other modules under the flywheel hooked up. I was frustrated and it was the end of the day so I stopped. I do have the 2SD1071s on hand I will try them in a couple days to see how they compare with the BD649s just need to take a break for a few days. Thanks for your help.
Rudderless,
Thanks for your insight as-well. i think I may mount my modules outside the flywheel also so I could switch them easily if they fail or just for testing especially on the 33hp since it already has 2 wires leaving the magneto area to kill the engine I will just re-purpose them for my needs to run the modules for testing purposes. I also have heat sinks I can use.
I did take pics but I am going to wait to post them once I figure out what I’m doing lol.
I have noticed that the brand new Black OMC coils that marine engine sells have not killed my Nova 2s but I haven’t ran them more than 8 hours in a 9.5hp 1967 I have them in. Possibly those coils might be better for running Nova’s and home made modules. I have also ran Nova 2s with the light green colored OMC coils made in Germany and they haven’t killed the Nova’s either in a 5.5hp 1960.
