B&D - Vector Battery Charger False F03 error codes.

I realize your problem is not intermittent, I only mentioned mine and hope it does not get consistent like yours. But that does seem to be a fairly common problem with these vectors and I hope someone finds a fix for it before mine dies like yours. I sure like that charger except for that problem. By the way the only time I have seen that error is on my lawn mower battery.
