Troubleshooting TXT PDS no go cart
I have a 2005 TXT Pds standard cart. We were out running around on it for about 1 1/2 hours with some out of town guest. 4 adults. Stopped for an hour and than attempted to continue our drive. The cart would attempt to move for about 6 inches and stop. I have read through other threads and had a few questions with troubleshooting this.
- Solenoid does click with peddle being pressed. -I put the cart in the diagnostics mode both under a load and with the rear wheels off the ground. I don't get any beeps with the wheels off the ground. Do I need to depress the peddle while testing? I did it both ways with the wheels off the ground. Also the motor ran and the wheels turned without stopping with the wheels off the ground. Next, with the cart on the ground, I get 2 codes. 2/1 and than 4/3. - To safely remove the controller cover, do I want to remove the last negative cable that is going to the controller or another cable? -I understand how to measure individual batteries, but I am not sure on how to measure the whole pack. Do I measure form the last positive and negative terminals that are going to the controller? Thanks, Rich |

Re: Troubleshooting TXT PDS no go cart
Both codes indicate low voltage supply. what is the pack voltage at rest now? and what does the pack voltage reading drop to when you put the cart in gear and try to go?

Re: Troubleshooting TXT PDS no go cart
Where do you place the leads on the dvm to check the pack voltage? I charged the batteries last night and will check the pack tonight after work and post my readings.

Re: Troubleshooting TXT PDS no go cart
When you look at the battery pack you will see all the batteries connect plus to minus (in series). There are only 2 battery posts who's cables do not connect to other batteries, these are the main (+) and (-) terminals. This is where you will read the total pack voltage.
Anxious for your test results |

Otherwise, you might take out the controller. Disconnecting either the main Negative or the main Positive cable works. In fact, disconnecting one end of any of the cables connecting the batteries in series works. I usually disconnect a cable on the driver's side of the battery pack since my main + & - terminals have several cables and wires on them. Measure the pack voltage from the last Negative terminal to the last Positive terminal. Labeled B- and B+ in attached drawing. ------------ Sounds like you might have just discharged the batteries too far, or had a battery failure. Was the hour and a half with 4 people on-board continuous driving, more or less? Charge the pack and see if it runs normally. |

Re: Troubleshooting TXT PDS no go cart
Thanks for the explanation on reading battery pack voltage and safely removing power. The driving was somewhat continuous. The batter gage was showing only 1/4 down from full. I guess they still may have been depleted to far or have a bad battery. I did charge the pack yesterday and still have the same problem today. I won't get home tonight until late this evening, so i will take the readings and post them tomorrow morning. I look forward to your reply. Thanks

Re: Troubleshooting TXT PDS no go cart
I checked voltage on J1 , J3, and J4. To be sure , the voltage is read with the peddle pressed? All were reading 37. 6 plus or minus except J1 #6 would drop to zero. The wheels would still spin.
Looks like that is the blue wire going to the "-" side of the solenoid, small terminal? What does that mean? Rich |

Re: Troubleshooting TXT PDS no go cart
Can you try a live load test. Connect the meter and drive the cart. Check voltage drop under hard acceleration preferably uphill.
