it depends mainly on the gap between pickup and magnet and of course on the speed of rotation. It's around +5v -5v at 1200rpm to +20v -20v at 6000rpm. Again it varies a lot depending on pickup coils... Just look at the scope trace: ruclips.net/video/nyDhEBxqRsg/видео.html it's +1volts and -1v but the gap on this bench is larger than a real engine.
What are the voltage values you're getting?
