New to me little boat.
It's a 99 2450 Hydra-Sports center console. Twin 225's. Yes, she moves out. Yes, she likes fuel.
My bonding system. Consists of transom anode, port hull anode(underneath) all thru-hulls and drain plug. All are connected to the same main 8ga green wire via smaller green wires as they should be. This main wire stops in the console. It's cut there.
The issue is in the rear(transom) area. That main green comes to a ring terminal and I do not know where to connect it to?
I get conflicting answers to this.
1..Connect the main green to the Neg batt terminal.
OR
2..Connect the main green to a ground BUS.
OR
3..do not connect it to anything. As long as all the metal in the water is connected(bonded) to each other it's doing what it's supposed to do.
This wire is long and has been connected to something back. It appears to be the battery terminal from the way it's worn.
It was not connected when I got the boat.
any help would be great. |

My take on this is to connect all your thru-hulls to your external anodes, as in your option #3. As mentioned, connection to your battery neg' may help with lightening strikes and your external anodes MAY be acting as a ground plane for your VHF radio but I'm not well enough versed in radio technology to suggest this is the case. Buss bar or battery neg? Both the same IMHO.

Actually the least amount of connectors on the battery the better so the ground buss is a better choice it's also less apt to get corrosion if away from the battery. As far as radio it does help with HF or SSB not so much on VHF FM.

there may have been other gear that was bonded at one point in time, i.e. trim tabs, underwater lights, swim platform leg etc. |

That is what I want to use. The less leads on the batt the better to me. |

I would use the common ground bar/buss if it were me.
Even small amounts of DC leakage can cause serious corrosion/ damage.

no AC or batt charger.
It is a dual battery dual engine 12v system.
It may or may not have had a 3rd battery or battery charger at some point.
I can hook that green DC to the Neg at one of the Batts or a ground BUS that is located right there also. Either is fine just not sure which one to use. Maybe it doesn't matter. |

Never connect the bonding system to the AC green.
I would connect it to the battery ground bar or negative on the battery that way your engines are at the same potential as the bonding system. The battery is already connected to the motors for obvious reasons this will also help with lightning strikes. Does the boat have a battery charger or AC inlet for shore power? If so you might want to install an AC galvanic Isolator in the AC ground between the inlet and AC panel do not hook this up to the green bonding system. I hope the bonding wire wasn't cut due to a problem with one of the DC circuits in the boat if so you have some troubleshooting to do. |

The common for all these, small and large, seems to be the port underneath block. It has a anode outside the hull. It's not in my sight but my hands tell me they all meet here. Both those large 8ga come from this block.
I just want to know what that ring terminal should go to or anything if at all.
As it sits right now, all the wires are attached to this block/anode. |

You will get different answers, but here is mine,
All underwarer metals should be bonded together, and should have individual wires running from the fitting to a bonding plate somewhere convenient, usually in the engine room. Daisy chaining is asking for issues when a wire is compromised.
All battery negative wires should also run to the bonding block.
Hope this helps. |
