How do I replace the throttle potentiometer?

The diagnostic light on a mobility scooter that flashes 7 times typically indicates a throttle pot error. This means that there may be an issue with the throttle potentiometer, which is a device that measures the position of the throttle lever or control on the scooter.
Here are some steps you can take to troubleshoot this issue:

1. Check the throttle lever or control to ensure that it is not stuck or obstructed. Make sure that it moves smoothly and easily.
2. Inspect the wiring and connections between the throttle potentiometer and the scooter's controller. Look for any loose or damaged wires or connectors.
3. Test the throttle potentiometer using a multimeter to measure the resistance across the potentiometer's terminals. Compare the readings to the manufacturer's specifications to determine if the potentiometer is functioning correctly.
4. If you are not comfortable performing these steps or do not have the necessary tools or expertise, contact a qualified mobility scooter technician or repair service to diagnose and fix the issue.

It's important to address any issues with your mobility scooter promptly to ensure that it remains safe and reliable to use.

According to the owner's manual for this scooter, flash code 7 indicates a speed control lever fault. This is the lever that you push to go forward and reverse. The lever is attached to a throttle potentiometer to control the speed of the scooter. The lever has to be in the middle or neutral position when the scooter is turned on, if not, you will get a 7 flash code. If the throttle potentiometer is damaged you will also get a flash code 7.
You can try to adjust the throttle pot or try manipulating the neutral position and turning the scooter on and off until the computer sees neutral. This is a potential work around and will cause the scooter to creep forward when running with hands off the throttle lever because there is no zero setting. I usually just replace the throttle potentiometer and this solves the problem. I hope this helps.

7 flashes could be speed or throttle, i recommend replacing both.

Get the service manual from Pride's website. It will tell you what the flashes mean and how to fix it.

Download manual it lists the codes

The throttle potentiometer error code is caused by a damaged or worn potentiometer. The fix for this problem is to replace the throttle potentiometer. The part is available from Pride based on the model and serial number. Hope this helps.

The throttle potentiometer, which the throttle lever is attached to, is a component that is very prone to wear. Often there is a bad or uneven surface on the sliding contacts that can give poor performance or surging throughout the throttle range. I have had to replace several during the warranty period. According to your beep code description there could be a bad or intermittant component or a loose wiring connection of the speed pot, throttle pot or front to rear harness. I usually replace the speed potentiometer and the throttle potentiometer at the same time because these two components are interconnected. There could be a loose connection in the front console or loose connector. It is also a good idea to check the front to rear wiring harness connectors and harness for cuts or shorts. This also gives a 7 beep code. Check for binding of the throttle lever on the console case and a bent throttle shaft and mounting bracket. If the scooter is less than a year old it should be covered under warranty. Keep in mind that replacing these components under warranty requires a factory certified tech at a dealer. I hope this helps.

The L.E.D. located on the tiller
dashboard will indicate with flash codes what problem is occurring.
L.E.D. Flashes 1 time and pauses, 1 time and pauses…. Batteries are low,
scooter will still operate.
L.E.D. Flashes 2 times and pauses, 2 times and pauses…. Batteries are very
low, scooter will not operate.
L.E.D. Flashes 3 times and pauses, 3 times and pauses….Over voltage to
controller.
L.E.D. Flashes 5 times and pauses, 5 times and pauses….Brake is in the
freewheel position or connection to brake is open.
L.E.D. Flashes 6 times and pauses, 6 times and pauses….Paddle or speed
potentiometer problem.
L.E.D. Flashes 7 times and pauses, 7 times and pauses….Paddle or speed
potentiometer problem.
L.E.D. Flashes 8 times and pauses, 8 times and pauses….Motor
disconnected or faulty.
L.E.D. Flashes 9 times and pauses, 9 times and pause….Controller fault.

I hope this helps they are pretty standard codes I got this from Golden Tech Web Site

The above link is to a diagram of your ALDL connector, all you need is a paper clip, straighten out the paper clip and insert one end into the diagnostic test pin and one in the system ground pin (terminals A & B).

Then put the key in the ignition and turn it to the on position but DO NOT start the engine. You will then see the check engine light flash. It will initially start by flashing once, then a pause and then flash twice and it will repeat this three times. That flash sequence indicates 12, which just means the system is operating. Its the flash sequences after that that will give you the code if any are stored.

For instance if it flashes twice, then pauses, then flashes four times, thats code 24. So any flash sequence you get after the initial 12 (flash once, pause, flash twice) you need write those down. Below is a list of diagnostic codes to tell you what the codes mean.
