club car DS wont charge

[Bubba11]

Have a 48volt Club car DS, the individual who owns it has a Modz Max 48 charger for it. battery pack reads 46.7 volts, when you plug in the charger it will kick on then will blink red/green which indicates bad battery. load tested batteries and they checked ok but one, replaced that battery. plug charger back in still blinking red/green. i did notice that the obc has been bypassed. black wire from receptical going to main negative. i also noticed that the grey wire has also been placed on main negative, should the grey wire be ran that way?

Thanks

My gray wire is just clipped off at the charger plug receptacle.
I think it was used to tell the OBC a charger was connected.
Try disconnecting the gray wire and see if it works any better.
My ModZ Max48 has been working fine for the last 5 months without the gray wire.
