Any advice?
99 Mercury 150EFI is charging 15.6-16.7 volts at 3/4 throttle. Charging 12-13.8 at idle - 1/2 throttle.
Both rectifier/voltage regulators have been changed, did I just happen to get a bad one out of the box or is there something else that could make it charge to much. Any ideas would be much appreciated.

All fishermen are legends in their own minds! Ranger Boats, Yamaha Outboards, Humminbird Electronics,Motor guide, and all the tackle in the world.

Measure with another meter to rule out instrument panel meter.
