sarv-3 alternator regulator

Postby lubr on Mon Mar 14, 2016 10:08 am

we have a nordhavn 64 with a smart alternator regulator v3 controlling two hydraulicly driven alternators. they are meant to be operated one at a time. both are showing the same symptoms in that they will cycle on and off in about 20-30 second intervals. the cycles go something like this, there is no output for a few seconds then the amps ramp up to 25-30 amps then there seems to be a momentary spike in amps just as it drops to zero again for a few seconds. nordhavn has gotten rid of this type of system on their newer vessels, looking for help trouble shooting this problem.serial #SARV3-24p-2.6-k06410016

Cycling is caused by wiring issues such that alternator current shift the battery and ground reference points the regulator sees.

A shortcut that is sometime taken by an installer is to connect Ground and Alt. Ground at the regulator and use one wire to connect the two wires to ground.

A second shortcut is to connect the wire(s) as some intermediate ground instead of taking them to the battery per the wiring diagram.
