Hi All. I am wiring up a flow controller and like the berk I am, got my + and - mixed up briefly. Realised after about 1 second. Swapped round and am getting The following display 99, 0, bat, oc. The 99 doesn’t display again just the bat, 0, and oc. Battery is fuller charged. Any ideas?
Hi David. Re read the first sentence of my post 😅. No fuse.
