    Default Tach/Trim problem 85 Evinrude 150

    I had an intermittent tach problem and tested the regulator/rectifier and found it bad. New rectifier is on and the tach appears to be working ok accept when I trim the motor up or down then the tach will show a decreasing reading. I am not locating a bad ground or a short. Any suggestions?
