08 Bad Boy Buggie need advice to trouble shoot

[eWheelz]

My research on this cart has provided some guidance as to where to start looking for the issue. This cart was fine until it just stopped driving in my back yard a few weeks ago.

The controllers blink four times to signify a lose connection somewhere on the controllers and or fuse box located under the cup holder. I cleaned all connections on the controller and fuse box and yet I still have the same four blinking light condition.

Also I did load test all the batteries and we have 49.8v on across all 8- 6v batteries.

Not sure where to check or test next, please advise. Thanks in advance!!

sorry this is late but you don't have enough voltage across the batteries. i will not work on a BBB if it won't fully charge above 50 volts.
