I have a BMV 712 installed and want to replace the Power Cable, the cable from the battery to the shunt that powers the shunt circuit board. It has a fuse holder in it that is not very weather proof and the fuse and contacts are all rusty. I cleaned the contacts and it is working but would like to replace it. Does any one know if replacement power cables are available? If so how do I purchase one? Thanks for any help/suggestions. -Don
