Re: Power output loss
Original poster: "C. Sibley" <a37chevy@xxxxxxxxx>
Have you by any chance taken a primary strike? I'm
using the same .03mF Maxwell and it began to slowly
degrade after a primary strike. The coil was still in
resonance but just didn't have the power that it did
before. Replacing the capacitor solved it for me...
