I am in the process of upgrading my battery charger to a ProMariner ProNautic 1230p.
I am a little confused about the two chassis grounding wires. “boats bonding system”?
This is the installation instruction;
3. Ground - This is extremely important and often overlooked. There is one common battery ground with the positive battery connections on the ProNauticP. There is also a “Chassis Ground”.
a. Battery Negative - As shown in the diagram, this is connected to a bus bar or terminal stud (not included) that can handle, at a minimum the amperage of the charger output (1260 = 60 amp minimum). This conductor shall be of equal size to the DC positive conductor chosen above. The battery negative terminals are connected to this bus bar or terminal stud.
b. Bonding Stud A.K.A Chassis Ground - This stud is connected to the boats bonding system as well as the bus bar or terminal stud mentioned above. This conductor is permitted to be one size smaller than the DC positive conductor chosen above; in the case of a DC to the case fault, this conductor is critical in carrying the fault current to trip the fuse or breaker, the AC ground CAN NOT handle high DC amperages.
