2012 48v TXT issue

I'll start by saying that I'm not new to ezgo's, but I am new to the delta q 913 charger. I recently picked up a 2012 48v txt with 2014 Trojan 8v batteries. The cart ran fine the first couple of weeks. I haven't used the cart I about 10 days, and it has been sitting in the garage connected to the delta q 913 charger. I have not paid attention to the led lights on the charger. Yesterday I had noticed that the GFCI in the garage was tripped, which in turn caused the outlet that the charger was plugged into it function. I unsure how long the GFCI was tripped.

Anyways, my wife took the cart around the neighborhood today, and it left herstrandedafew blocks from the house. She described that the cart seemed to be losing power, and she would let off of the throttle then get back on it and eventually the cart had no power.

Water levels are good in the batteries.

I plugged the cart in today, and the lights shown are as follows
Yellow Light on 4 bars at top
Yellow Light on half battery icon(4th from bottom)
Yellow Light on squiggly line (2nd from bottom)

1 1/2 hours later, the lights shown are
Yellow Light on 2 bars (5th from top)
Yellow Light on half battery icon(4th from bottom)
Yellow Light on squiggly line (2nd from bottom)

30 min later
Green light on full battery (3rd from bottom)
Yellow light on squiggly line (2nd from bottom)

The light is green at the plug connection on the cart.

Turn the key on, put the cart in FWD, I hear the solenoid click, but the cart doesn't go. Prior to charging, the solenoid would not click at all.

Thoughts?
