Cabling problem -- Cableguygreg???

NickWight

You may remember that I posted a few weeks ago about a problem that showed all the signs of being a failed house battery -- well, it wasn't! Briefly the situation now is that after much investigation and cursing it seems that we have lost a battery neutral somewhere and if I strap directly across from the house battery neutral terminal to the busbars that are located on the starboard side transom in the engine bay everything works as it should with no problems. The neutral cable that leaves the battery is larger than the one that arrives at the busbars and I assume that "somewhere" in between there is another connection, but without pulling all of the wiring apart in the engine bay, I cannot find where that might be.  Does anyone know where it is? This is on a 2008 280ec.

Hopefully someone on here can get you a wiring diagram.

Here is the wiring diagram, hope it helps.

I am not sure where the black from the battery goes, but I believe it goes to the engine block.

Thanks Aqua Aura for the wiring diagrams -- very useful! I'm back at the boat in a couple of weeks and I will investigate further then.

The diagrams are more logical then physical.  Meaning they show whats connected to what, but not where the actual wire runs or where to find it.  Still really handy to have.  I have the 342 diagram, but it still can't tell me where to find the other end of the wires connected to the ACC switch at the helm.

How many wires? I had 2 ACC switches and the those connected were the feeds, not the outgoing.

The wires for my ACC switch were only 5 inches long and had butt connectors already in stalled.
