Your 48v pack is DEAD at 45.5v. Not enough to power the motor. You need to charge each battery with an automotive charger for a while until the cart charger is happy with the voltage it "sees" when you plug up. Then the cart charger can finish the job. Be sure the plates are covered with distilled water before any charging is attempted.

Its time to get a hydrometer with single float and temperature correcting scale on side and check each cell for bad batterys after waiting at least one hour after charging. The two batterys ( #5-#6 ) under drivers seat seem to go bad first for some reason?
Sounds like some new Trojans are heading your direction?

batteries are 3 days old but when you bypass the relay in the charger it comes on cables are on right it ran good then it died thats when this all started happening buy i will try the car charger

SORRY HAD NOT SEEN YOUR POST ABOUT 3 day old batterys until after making my post.#1 You should always charge "NEW batterys" before driving for first time and never let them get much below 75%-80% at most until charging for 10-20 charges.
#2 Do as Gornman says and use 12 volt auto charger but monitor condition often as 8 volts batterys dont like 12 volts for very long.
#3 Sorry to say that NEW BATTERYS are some times defective, in the case of Trojans thank heavens not very often caompare to some other brands?

I think you've got a bad on-board computer or a bad charger relay. 45.5 Volts is more than sufficient to make the charger turn on. Check the fuses behind the charger receptacle and the #10 red wire running to the main positive post on the #1 battery (Pass Side, Rear) Make sure all that looks good. If so, you'll either need a charger relay or an OBC.

checkyour charger on another cart to see if it works.........make sure you don,t have a charger problem.....................................

no guys i have two chargers they both work if you by passthe relay in the charger it turns on but when i plug it to the car it does not charge it i dont know why the other charger you plug it in you here a hummm but the meter does not move with the charger pluged in i put volt meter to the batteries pack and no different in the volts still 45.5 also the selenoid clicks when the pedal is actavated

i would lean towards the OBC being the problem and thats not uncommon for the cart and even more so if its a 1st generation OBC they did have issues with them....................................
