Shudder
Im working on a 97 ez-go 36V the batteries were completely dead when it came and I had to charge 2 at a time till I got the normal charger to kick in and then it charged them to 38 volts. 4 hours after I disconnected the charger it was at 36 Volts so the batteries are not good . but when I push the accelerator the motor shudders and then it will start to move. if I mash the throttle it just shudders. I check the drive splines on the motor and they are good. Could the Inductive throttle sensor be bad ? I noticed its not centred with the plunger does that matter ? I checked the voltage at the motor and its the same as at the batteries .

Re: Shudder

Re: Shudder
Monitor the battery voltage when it "shudders". I bet it's dropping. Sounds like bad batteries to me.

Re: Shudder
Looking at your pics the plunger would be closer to the left side than the right. and it doesn't look square with the plunger. I think the batteries too but I want to be sure. I think when it shudders it reads 28 volts.

Re: Shudder
28v? Just junk batteries, no need to waste time diagnosing ITS with batteries like that.
