I am using the LS1 coils, and I did = have a 15A fuse blow on one set of (3) coils. It apparently happened on = startup (I don't recall doing anything behind the panel that may have caused it), = and apparently under the right conditions, a high draw can occur when things = are turned on. The engine, of course, still started and ran on the other = set of coils, but I could tell something wasn't entirely cricket. I have looked for slow-blow blade-type fuses, but have not found them. Just as a reminder, the estimated loads are useful in sizing wires, but circuit protection is selected to protect the wire; not the load.

I even looked in the RX7 manual to see what size fuse Mazda used. It just says the fuses are listed under the cap.
