I have tested my regulator on the 682. The test guide on the OCC site shows 13.7 volts max output but other test I see on the net say 14 to 15 volts max. My regulator is running 14.5 to 16.5 at WOT and almost pegging the gauge. Ive actually tried two different regulators with the same results. Occasionally the tractor will blow the 15 amp fuse in the dash. What is the true maximum and were do I start to solve the issue if 14.5 to 16.5 is to much volts?
