I am getting consistent voltages across the battery in the 15.5-16.1 V range. This voltage is reached before 1000 rpm and maintained at higher speeds, which suggests the regulator is regulating. I realize there is temperature compensation and that specified regulator voltages can be very close to 16 in cold weather, but it seems excessive, and I would think a full battery would bring the volts to the low end of the range for a given temp. Also, my ignition coil is getting hot if idled long enough (stays cool at high speeds). I am concerned that the high voltage is taxing all of my electrical circuits needlessly.

Things I have checked/done:

1. Installed new battery. Old battery worked fine but tested bad at the local parts store.
2. Installed new regulator. Old crusty regulator was delivering the same voltages.
3. Cleaned battery ground connection and terminals.
4. Checked wiring from gen to reg, polarized gen.

Do you think the regulator needs to be adjusted?
