Seanwinder22 Posted July 12, 2022 Share Posted July 12, 2022 Hi everyone some help needed My starter battery in my motorhome the negative wire goes to ground earth but my leisure battery the negatives on this I followed which one is the solar & the otter goes to a mptt controller and the last to the Nord ne221 fuse board that is it I can’t find a negative wire that goes to ground is this a issue ?? I have noticed 2 positive wires come from the starter that run to the ne221 fuse board which apparently has a relay on the back for a split charge to charge the leisure battery & starter battery but no negative runs back to the starter battery I have found x2 negative wires on the back of the ne221 which that’s 1 of them that runs to the leisure battery I mentioned above the other I can’t see what area it does go another 2 positive wires come from the ne221 fuse board which goes to a 40amp fuse then to the leisure battery So I be running a wire from the chassis to a bus bar for any earth I need and a negative bud bar so all negative wires mentioned can also go to Link to comment Share on other sites More sharing options...
