To start - I have a 97 225hp yamaha saltwater series OB. I suspect I have a bad volt reg, but I wanted to get a second opinion before purchasing a new one. The conditions that i'm getting are, 1)no engine rpm readings, but the other functions of the gauge are fine. 2)batteries were "dead" only after sitting for a week. 3)while underway, when i trim the motor and/or tabs, my voltage readings go from 13.2 down to just under 10v-depending on how long i utilitize the controls. The batteries were replaced last summer, and they do hold a charge while out the for day. Any comments or advise will be greatly appreciated. Thanks in advance...
