Had a chance to do some testing on the MC. Here are some of the #s. Battery rested 12.4 vdc, remotely located coil installed spring of 2011 is 3.3 ohms and EI. After a 30 minute run under load the coil + readings, 13.38 @ 900 rpm, 14.07 @ 1600 rpm, 14.2 @ 2000 rpm. All are producing above the 4 amp upper limit. I did not have a way to check coil temp but I can say it was never to hot to keep my hand on it. Very subjective I know.
Other thoughts:
I ran for years on my old coil before it failed this spring. Many hrs at 2000 rpms. No idea what resistance it was. Prier to the spring trip I did some "spaghetti removal" and connection cleaning. Also about 7 days before the failure, the morning my wife flew into Marsh Harbor of course, my old 4 way, off/fan/fan-ign/ign switch died and as I rewired I eliminated the switch and several feet of wire from the ignition wiring.
Any harm in just putting in a 1 ohm resistor? That would easily cover my high, 15 vdc, Edit "estimated" reading but would only provide 2.92 amps at my lower,13.15 vdc, reading with the spare coil that is 3.5 ohms. Dan S/V Marian Claire
Edit: I should point out that I normally cruise at 2000 to 2400 rpms.
