I just got a Mint in the box MTH MP15AC switcher.

It wouldn't run and had bad battery symptoms. Would re-start whenever the direction button was pressed on the Z4000.
After charging all night, it only read 1.5 volts.
I swapped out for a BCR and it now runs. At first the volume kept cutting out in conventional mode. Found the volume pot was turned off. I don't know why it starts with volume? I always run command and have to learn these things.
Anyone got a CSX MP15AC they want to trade or sell???
