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 get F03 sometimes when the charger thinks the battery is full or even if there is another charger with a higher voltage than the Vector on the battery. In that case, I must start the Vector first and get it running and then start the higher voltage charger.Try knocking the battery voltage down a bit and then start the charger.

Please do not toss them in the trash Yes they can very easily be repairedOpen 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

I just now hooked it to a battery that reads 12.0vdc, it displayed the F03. It does know when it has been hooked to a battery, because it doesn't display the F02 that it does if started when not hooked to anything.

I don't have a lessor charged battery to test with right now, but will crank the mower a few times (with the kill switch on) and see if I can get the battery down a few tenths.EDIT - I just cranked the mower starter until the battery read 10.4V, and started the 1097. It did it's F03 thing......

Could try and fool it back to being normal. Start it and then clamp on? When on and showing F03, change amp settings up and down and turn on and off, change battery type.Sometimes with the old 27DCs after they were FUL and I wanted to do more, I would get an F03 but not if I just used the 2 amp setting and not the higher settings. Once it started ok in 2 I could then ramp it up. Seems like F03 is for almost anything, not just for what it is listed for. Weird.

Just saw your reply. I've never tried to take one apart, but it sounds like a good project for these last few weeks of winter.

I had to chuckle at that, because that's exactly what I just did (and felt kinda silly doing it) with no good results.

I wish I had all the other old 1097s here to see if they all still would act exactly the same way under all tests, but I don't. I think I remember some (one) of the others as being intermittent in the beginning, before failing solid.

I was just hoping someone here had a ready answer on a repair or mod that would make this charger useful again.

Thanks for the replies anyway.
