2008 EZGO PDS Cart

Owenr · 01-06-2012, 05:06 PM

I am using the charger that has the meter on it. It don't have no type of modes on it. Will check cables and voltages in a couple of hours. No, I not washed the cart in 3 weeks.

Owenr · 01-06-2012, 08:03 PM

Readings after 15 to 20 min of riding:

1- 6.32
2- 6.32
3- 6.25
4- 6.30
5- 6.29
6- 6.29
Total- 37.6

No wires were hot at all, motor and wires that attach to motor were not hot either.

I think your batteries are showing their age, but they are staying close together in voltage, so none have a bad cell.

You didn't specifically say, but I take it that the cart was still slow with the battery pack at 37.6V (85% SoC) and above.
My cart still does about 18MPH @ 85% SoC, so while your batteries aren't up to par, I don't think they are the primary reason for the slow speed issue.

In your first post you stated you've checked the ITS (Hopefully, you verified the ITS voltage to the controller was in specs) and replaced the Speed Sensor in the motor.
In your latest post you state the none of the cables or motor are getting hot after 15-20 minutes of pedal time.
If you had a mechanical drag of some type slowing you down, the motor would have been pretty hot.

That eliminates everything except controller, solenoid and motor.

If the cart is running smoothly, but slow, and the motor isn't getting hot, the motor is probably okay.

To eliminate the Solenoid as the culprit, attach your DVM across the big terminals and measure the voltage while driving cart.
It should not read more than a volt or so, if any, when the cart is at max speed.

If the solenoid is okay, I'm afraid it is time to replace the controller.

PDS controllers have some weaknesses, so when mine goes I'm going to replace it with an aftermarket one.
I'm not making a suggestion or recommendation, just providing some food for thought.

Soon after I got my buggy, I adjusted the plunger in the ITS using a drill bit to get the proper distance, with info located somewhere in the stickies. If I recall, you also have to adjust when the micro engages. Once I did that, I got a noticeable speed improvement, as the controller was never told by the ITS to go to 100%.

It did not get faster with full charge batteries. I did adjust the ITS but it did not make much of a difference. I will check the solenoid tomorrow.

Well, how's your solenoid?

Owenr · 01-09-2012, 01:32 PM

It will be tomorrow before I can check. Pulling 16 hours at work today.

Coltf1991 · 01-09-2012, 02:16 PM

NICE!!!! Well after this shift you will have money for a new controller

Owenr · 01-09-2012, 02:23 PM

Man, I hope so, these auditors are killing us, but we will win at the end. How much is a controller?

Depends on your cart, how big you want to go and what you want out of the cart
