Club Car 48 Volt Slow Accelerator Response

[Paparick]

What would cause slow response to the accelerator pedal? If I press the pedal fast it doesn’t get all the power. If I press it slow it gets all the power And it start to stutter(seems to lose power) Any idea’s? Also my Alltrax control switch to 50 power. I have a brand new 48 V motor brand new batteries that are six months old. Very confusing.

I'm having the same issues. Mines a 1995 Club car DS. I switched out batteries with another cart I have with newer batteries and 4ga cables, and same results. I was told to switch out the motor that the motor may be tired. I also was told my speed sensor needs to be replaced. I noticed its much slower on hills than my other cart as well. Bottom line, still confused.

Well without knowing for sure what you have it's probably just a tired old series cart no speed sensor.

I would think the same if I didn’t replace the motor and the battery cables and the controller. All new 6 months ago. it just starting doing with a few weeks ago. I guess. Back to the shop it goes. Also I have a 1993 DS. And it has a Alltrak 500 amp controller with a high speed high torque motor.

What measurements have you done voltage wise where did you do them something is not passing voltage to the motor wires controller solenoid batteries

And frankly taking an old series car and putting all of that money into it an AC kit with a new wiring harness would have been your better bet now you're into the 30s with much less drain on the battery.

Measurements are 48 Volts at the battery. I have not tested under load yet that is todays mission.

True but I Don't need that much speed. If I can’t figure it out, I’ll sell it and get a newer one.

Could it be the MCOR box?

I will check that. It is possible

My thoughts exactly, you want to check the wires coming from the solenoid to your battery to make sure they are not corroded first. Then you may want to do a voltage test on it but if it's an older cart just buy a new 48v solenoid with resistor and hook that up. If the issue still persists, speed sensor - mcor replacement.

Thanks Argonaut. I replaced all the wiring starting at the batteries to the motor. Solenoid was replaced as well. At this point I am going to just replace the speed sensor and see if that works.
