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.

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

Please be more specific. Any flash or beep codes? Make\Model\Year of scooter? Is wig-wag pot {potentiometer} within tolerance? [5,000 ohms +/- 5%]

look on the inside of the door that you took off and there should be a diagram and on that there will flash code that will tell you what 4 flashes means.i think it is a flame rollout or high limit.

Just some suggestions.
Clean the end of your key and get an earbud and metho/alchol and clean the keyhole sensor.
Change the battery in your key.
Check the charge level on the battery. Recharge.
Check alternator charging.

Item 63 is the input signal from the thumbwheel controlfor the center vent, and 64 is the feedback signal to the controller giving it the position of the vent flap. As you move the thumbwheel these values should continously vary from a minimum of roughly .7 to 4.5.

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

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

1. Make sure the unit is turned on, and not printing. The POWER light should be on, but not flashing.

2. Lower the OUTPUT tray, and lift the scanner portion to access the ink cartridges.

3. Press and release the INK button. The print heads will move to the left, and the cartridge that needs to be replaced will stop directly beneath the OUT OF INK symbol. Make a note of which cartridge requires replacement.

4. Press and release the INK button again. If more than one ink cartridge is empty, the next cartridge will move under the OUT OF INK symbol. If no other cartridges are out of ink, the print heads will now move to the REPLACEMENT POSITION.

5. Open the CARTRIDGE COVER. Pinch the front and back tabs of the empty cartridge as you lift it out of the unit. Dispose of this cartridge.

6. Before you remove the new cartridge from its package, shake it four or five times.

7. Remove the new cartridge from its package, and lower it into the cartridge holder. Push down gently until the cartridge clicks into place.

8. Repeat steps 5-7 for each cartridge that you need to replace. Close the CARTRIDGE COVER once all of the necessary ink cartridges are replaced.

9. Carefully lower the scanner, until it clicks into place

10. Press and release the INK button.

The ON light flashes and the printer makes noise. Charging takes about 30 seconds. When it's finished, the ON light stops flashing and stays on steady.
Caution: Never turn off the EPSON Stylus printer while the ON light is flashing, unless the Stylus printer hasn't moved or made noise for more than 5 minutes.
