T&E and Split relay back feeding
The T&E makes a lot of sense about the conduit. I have seen some cable in terrible shape that has not been anywhere near these types of environment. What is the price increase for this type of cable?
How about back feeding from the main battery to the leisure battery when you turn the key to ignition position? I had left my old van standing for weeks with a small light draining the leisure battery. When I turned to ignition the main battery drained into the leisure battery, draining the main battery and melting the relay. Any products available to prevent this from happening? The ultimate cost of this was two new batteries and a new split charge relay system.
