Club Car running slow

jeff0181

I have a 2004 48V DS electric Club Car (at least I think that is the year and model based on the serial number starting in AQ0422) with 6 Duracell GC8 48v batteries.

A couple of months ago the golf cart started to run weak, wouldn't get to top speed and can barely make it up small hills. I keep it plugged in and the charge is reading 55.6v. All battery terminals are clean and battery terminal connections are tight.

Any advice on areas that I can start to troubleshoot would be greatly appreciated.

How old are the batts. ..?

30 minutes After the charger shuts off, what is the pack voltage ?
&
What is the volts on each individual battery ?

The pack voltage of 55.6v was read with the charger indicating that it was off. Had been so for a bit when I measured it. Lowest individual battery read 9.3v. Batteries are just under 2 years old.

Try this speed sensor test...

You can do a simple field test if You have a voltmeter on the cart.

Drive up the hill that it can barely go up, if the voltage gets below 42v, you need to check the batteries.

If the voltage does not drop below 48v, check the motor cables (A1 and A2) for heat.

If the cables are cool, You need to check the MCOR to see if it has the proper range.

30 minutes? You will still be reading an inflated surface charge...

As mentioned by Sergio in lieu of doing an actual amperage load test which requires specialized equipment the reading of the voltage while under load is one of the best tests one can perform.

Another effective test would be after the charger has completed the charge cycle. Remove said charger and allow batteries to rest for at least 8 hours and upward of 24 hours. Then measure battery voltage as a pack and individually too.

After charger shuts off ,
how long should you wait so Not to be reading surface charge,
12 a 24 hours?

teecro

As I commented at least 8 hours and preferable 12 to 24 hours later so that the surface charge has dissipated, a 100 % fully charged 8 volt battery should read 8.5 volts after 24 hours of pure rest...

Thanks

Tired that today. A little bit of chirping from the buzzer and resistance was noted. Thanks for the link and pointing me toward the right direction.
