To help solve your problem, a description of what the golf cart is doing will be necessary.

There are several people on this board who work in the industry that should be able to point you in the right direction once they know which direction you need to go.

I have two in particular. both club car 48 v electric.one 99 model does nothing at all when accelerator pressed. 48 v across batteries no low voltage at motor a1 a2 f1 f2 when depressed previous tech diag. solenoid i replaced no change. this cart was working fine previous tech replaced steering box and went to move it then it wouldnt move. 02 model shudders when pedal depressed 48 v across batteries. have 48 v at a1 a2 0v at f1 f2. replaced speed controller,tried known good solenoid and accelerator switch no change.

48v across batteries is 45% state of charge. That is a low pack voltage which can cause the shutter issue on you 02 and could possibly be the cause of the 99 not moving as well. You need to charge the battery packs on both carts and go from there.

if your getting a shudder when trying to move look for a junk battery......either 1 or more could be failing under load....makes no difference if it holds voltage check each one with a load on them..........................

these batteries were replaced on the 02 within past 2 months will load test and charge though to confirm thanks

those batteries were bone dry and 3 load tested bad filled em up and cart started moving put on charger will retest in morning. thanks got to remember basics first.

If they were bone dry, chances are they are toast and wont hold a charge

Brought em up and they are holding right now.The 99 turned out that the obc was not grounding solenoid supplying power to controller,jumped to ground and it ran.Replaced obc and problem solved. thanks for help
