Help, voltage regulator ?
Hello Folks, This questions is regarding a 1961 evinrude 75 HP serial number 03158 ,model number 50927. I believe everything is wired correctly. I have rewired the ammeter by connecting the #10 brown wire from the rectifier to one side of the ammeter, the other side of the ammeter is going to the fusebox where the temp warning light,ignition/power lamp, tachometer lamp, cigarette lighter and navigation lights will be connected. none are currently wired into the system as the former owner disconnected everything for some reason, so there is currently not much of an electrical load. A possible reason for disconnecting everything is that the system is currently putting out between 40 and 50 volts. if i read the manual correctly the test for the regulator is to ground the field terminal of the regulator and the voltage will rise to approx 40 to 50 volts.Well i checked the field terminal(blue wire) to ground and it showed continuity. I disconnected the reg. and checked the wires to the alt.Blue wire to ground --no continuity, red wire to ground-- no continuity, red to blue 4 ohms. Field terminal of the reg. to the regulator case showed continuity. My limited skills say it's a bad regulator. Advice please
