3-Hour Battery change

[petethepug]

You’ve been offered sage advice on swapping out -/+ battery cables as something that should have been done @ years at year 10.

Your CanBus operates on 5v. Any resistance in the arteries from the heart will trigger a gremlin, waste your time and peak your frustration. Start with new wires because you should spend time with bride, not chasing false codes.

As a purely preventative measure will go ahead and look into getting some new ones.
Hard to argue with your logic.

I assume this large positive cable with inline fuse is the primary culprit. There's also another that goes from it to the alternator for charging, plus the negative post to engine block cable. Are all of these problem prone, or mainly the pictured one?

Appreciate the advice!
