pds loosing run time

Take a closer look at the specs.

The Deka GC8V is 165AH and the T-890 is 190AH
The Daka GC8V is comparable to a T-875 (170AH)

I'd go with the T-890.

For Scottie or Johnny - I decided to go with the US 8VGCHC XC batteries. I am going to replace all batteries up to 48v. How do I connect to the alltrax controller and change it from 36 to 48 volt? Is there an external dip switch or do i need to hook up a laptop to the controller. If so where do I get the cable? Thanks for all the help.

It is computer programmable. Get a 9 pin serial to USB cable at any office supply or electronics store. Download the program from Alltrax.com. Make sure the controller led is lit up before you open the program or will not 'find' the control. Once in the program raise the voltage under and upper limits. Something like 38-60v for 48v operation.

I didn't read all of the post, but since you got an ok from Scottyb about the load test, would/could it be that it's a very cold period in the year and that should affect the run time as opposed to an 80* summer day?

Hey guys new batteries are installed and I changed the voltage to 38 to 60. When I press the gas pedal the dcx is green then flashes 6 times. Any clues what to look for? The solenoid is not engaging with the click like it was. When i put the meter on it the meter beeps like there is connection without the pedal pressed down.

What is the voltage between the B- and B+ terminals on the controller before the pedal is pushed?
After the pedal is pushed?

In the continuity mode, your Fluke meter is beeping when you measure between the solenoid's large terminals?
Are the high current cables and the resistor removed from those terminals?

What is the voltage between the solenoid's small (coil) terminals with pedal up?
With pedal down?

With pedal pressed it was 36 volts the pedal not pressed 49 volts. Any ideas guys?

6 flashes on alltrax controller.

Six RED flashes mean low voltage. Six GREEN flashes mean the throttle input is set for a Club Car.
IF the voltage reading you gave are between B- and B+, AND there isn't smoke coming out of the motor or other component, the solenoid contacts are not closing.

Troubleshoot the solenoid activation circuit and fix it.
Here is a schematic with Solenoid activation circuit highlighted.
The B+ path is as follows:

B+ to Solenoid - DCX Controller in a PDS cart

a. The Reed switch is the B+ source, or wherever it is connected to, if bypassed.
b. J1 Pin-4
c. J3 Pin-3
d. Run/Tow Switch
e. J3 Pin-4
f. Jumper wire in Adapter
g. J1 Pin-1
h. F/R switch
i. J1 Pin-3 (If in F or J1 Pin-2 if in R)
j. Diode in Adapter
k. J1 Pin-9
l. Keyswitch
m. J1Pin-8
n. Jumper wire in adapter
o. J1 Pin-7
p. Small terminal on solenoid.


Once you get the solenoid contacts closing when they are supposed to, we'll troubleshoot the high current circuit, if needed.

Jonnie what am i looking for when I test all of these items? Am i looking for 48 volts to each one? What is B+ and J1, J3. I am not familiar with most of this.

Are the flashes red or green?
