I have a Mercury 2016 150Hp outboard SN 2B202320. The battery went dead. I charged it up and put an amp meter between the post and the negative lead. it was drawing 2.5 amps. When I disconnected the 2 wire lead to the alternator the draw went away. I connected the battery and put the meter between each of the pins and their corresponding contacts and saw no current draw. I then checked the voltage on the contacts there was battery voltage on one. I turned on the key and saw battery voltage on both. I removed power cable from the alternator and did a continuity check between each of the 2 pins and the terminal of the alternator to ground. There was no continuity. I connected everything up and ran the engine at 2000 RPMs and I read 14.5 volts. So I am having trouble believing the alternator is bad. Does anyone have any suggestions on what else I can check? Any guidance would be greatly appreciated. Thank you.
