Most of the time when I run into this problem it means there is a malfunction in the actual unit itself. More than likely you will need to replace it.

My same symptoms are - after starting charge, Red light is on, then second light turns On. Then for a long time nothing happens. And later I have all three LED flashing.
I replaced battery and nothing changed.
Imeasured Power Supply voltage and found it 24.2v instead 28v as it stated on the label.
I opened it up and found that the three-lid chip marked 431 is faulty.
431 is a voltage shunt, which sets and controls output voltage.
You can use AIC431CUS or TL432 (TL431 has different pinout).
I replaced mine and volatge back to 28.25v and charger is now working as it should.
You can also use any TO-92 431 chip - there is enough room for it.
Good luck!
It's only a few months old though! And I have lost the receipt. Looks like I'll be buying a new one, thanks though.
i take mine off the charger just for safety seasons dont like leaving things plugged in after its charged.
