2004 Honda 225 Alternator problems

I am having trouble diagnosing a alternator issue. The engine is a 2004 Honda 225. My starting battery has been draining down very quickly on the last few runs. I checked my alternator with a multi-meter. It is reading 2.78 volts directly at the alternator power post. When I remove the harness plug it puts out 12.87. I can only assume the ECM is telling it to put out the wrong voltage. I have checked all my connections and any possible failures between the starting battery up to the alternator. Any help would be greatly appreciated.
