Hi all this is my first ever boat. 1986 mercury 45 classic 50 on a 1987 bass tracker. I've noticed that when I'm running WOT for an extended amount of time (5 minutes+) my battery level goes to 18V. I've read alot of posts that say anything above 14V is bad. I replaced the rectifier with another one assuming it was a bad rectifier/regulator but that did not solve the issue. It still puts out 18V when running. Thoughts on the issue? It might be that the rectifier part of the circuit is good but the regulator is not doing its job.
