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

I have owned three Vector 1097A chargers over the last eight years and they have all developed the same.... failure? Trait? They give false F03 errors. One I returned under warranty, one I threw away and the last one I still have.

Is there something that I'm doing wrong (abusing or misusing) with these chargers. Is it coincidence, just bad luck or what?

I can charge my riding mower battery with my old HF 10amp charger and it will charge okay, but if I then attach the 1097A it will read the battery voltage okay, and I can initiate a charge cycle, but it will run for a couple of seconds, step the charge rate down to zero and display the F03. It does this with any battery (in any state of charge) that I try.

Can these beasts be repaired, or do I just throw it away?
  • 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.

    Dont'cha just love how they can take a simple charger and screw it up?
    LOL!

    Yes they can very easily be repaired
    Open it up and take a look close look at the large Capacitors
    If any signs of anything abnormal replace the part
    Parts available at DigiKey and typically less than $5.00
  • Hi I have one of those as well and it keep giving me FO3 code on any battery a try to charge. When you say to look at the large capacitor, do you mean a ciramic one or electrolytic one.

    After years of frustration I threw mine in the trash and my angst finally came to an end :) !!

    Replacing "caps" does not "fix" everything, the charger is falsely seeing/sensing a battery voltage higher than it should.

    That error is most likely the "processor chip" and or other ICs in the unit and no amount of caps you throw at it will fix that. Seriously doubt that you are going to buy an off the shelf processor for that device.

    These chargers super impose high frequency voltage spikes into the DC voltage of the output, chances are those same high frequency voltage spikes are causing the false high voltage detection.. The question becomes why and how. Chances are you would need an oscilloscope to view the waveforms and voltages but without any diagrams or notes on what you should see it is going to be a guessing game. It would take a lot of detective work to reverse engineer the how and whys of that device and even then the question of the possibility of a repair being successful is not assured.

    Sometimes you can make a device so smart, it becomes dumb.

    Those "smart chargers" are basically a throw away device, they are not built very robust nor designed to live a long life.

    Chalk up another win for the old school tried and true "dumb" charger, they just plain work.
