'50 sidemount N, 12 volts.
So a few weeks ago I got the Pertronix electronic ignition. Fired up first time once I figured out how to mount it, runs good.
HOWEVER, after mowing for about an hour, current started increasing, from an initial 1 amp or so, up to almost 10 amps. I noticed that and ceased mowing.
My theory was, coil resistance was decreasing as it heated up, and I wasn't sure if it was the recommended 3 ohm coil, so I got a new Pertronix "40,000 volts" 3 ohm coil, and am experiencing about the same. After about an hour, current had gone from initial 1 amp or so up to about 6 amps. When I put it away, I checked the coil, and it did feel fairly warm.
Did not have this behavior with the points.
One year old maintenance-free battery, any ideas ?
