Sent my Cab 2 to Lionel and they replaced it with a used unit. Not quite as nice looking as mine (which looked new). Battery charging worked ok for a couple of weeks. Now when I put the Cab 2 in for a recharge, I get alternating flashing red (good) but within about two minutes it goes to both flashing red at the same time. Batteries do not charge. I put a meter on the batteries and all show about 1.2 volts.
I suspect the charger is bad? Or is the circuitry in the Cab 2 bad?The room is about 65 degrees, so batteries shoild not be warm.
