1976 merc 115hp inline 6<br />been having batt troubles, but i cleaned the terminals real good, think that may have been a problem...BUT...<br /><br />at fast idle, about 2000rpm, im getting 12.71 volts at battery terminals<br />im also getting 12.71 volts at rectifier<br /><br />with engine OFF, i get 12.9 volts at batt terminals...<br /><br />why would it be higher voltage with motor off, is my recitifer gone the way of the do do bird?
