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?

Theses controllers are very sensitive to wrong  polarity , give Ian Shepperd a ring at spring controllers , Ime guessing it’s blown the circuit board or something.

Did it blow the fuse first that should protec the unit

Hi David. Re read the first sentence of my post 😅. No fuse.

Hi David. Re read the first sentence of my post 😅. No fuse.

First sentence of your post says 'Hi all'.

You don't say anything anywhere about you had no fuse. But like Splash said, I'd get in touch with Ian Sheppard at Spring.

Ok. Second sentence. “Berk”.
Opened up the front and there is damage to the board where the wires enter. Pretty sure it’s toast.

You've blown a capacitor on the circuit board.  A buddy of mine can usually fix them for a small fee.

Who is this guy David? Is he local to here?
