Re: normal performance 10 min of use then drags like...
Hi, now there it could be one of two faults, the brake magnetic core is not releasing the brake after a period of time, it's breaking down , other-words it's dragging or the voltage from the controller is not high enough or not enough current , a controller fault...check the wiring going from the controller to the brake... now a simple test would be to remove the brake but still have it connected via the two wires and tape on to the motor now you must be careful here because the scooter will roll if near a incline etc...so you been warned !!!! ... does the scooter run okay now ?

hi Diane, the brake engaging is by design, distance is the key here
Have you tried another charger ?
1. when pushing the scooter in freewheel before the brake engages , is it easy to push ? what can happen is the brake does not release 100%, a easy test is to run the scooter then put your hand on the brake unit , is it hot ? be careful because it could be very hot , this will prove the brake is not releasing fully.
New Batteries must broken in, For the first 20 Charges, do not allow the power level to go below half way before recharging. Charge the batteries in a warm environment. Also, if charging in a cold environment the batteries won't get the best range. Batteries have 60% of their capacity when the temp. is 32 degree F. At 0 degrees F. the batteries will only have 40% of capacity. Batteries have shrinkage. Good news the capacity best at 80 degrees.
If the brake is hanging up, it will cause drain on the batteries. A sure sign is, if they are hanging up is after 10 min. of running the brake will be very hot to the touch. It sometimes turns the brake blue in color or rusty.
The brake engaging while in freewheel mode is supposed to be a safety, to keep run-a-ways from occurring. I agree with you it is aggravating when you try to push the scooter. Scooter Doctor App

Sandi Count the number of flashes ie: 4 flashes pause 4 flashes pause etc. This will give you the flash error code and your users manual should tell you what the number of flashes indicate. (for example 3 flashes bad brake) Also check to make sure your scooter is not in freewheel. Turn off the scooter and move the freewheel lever in and out of gear a few times then turn the scooter on and see if you still get the flashes. If you can't figure out what is wrong then contact your provider and ask if they can check it out for you. Hope this Helps
Try changing the coolant sensor. I'll bet your gas mileage is less than normal too. The sensor is not reading correctly when hot & is not allowing the computor to advance the timing to adequate levels thus the poor performance. It is located near the thermostat housing. You may lose a little antifreeze when you remove it. Also if you unplug the sensor when the engine is hot, it will run much better in the meantime. Just plug it back in for start up. Hope this helps you. Good luck!
It would be good to make sure that the 951 software is up to date. The most recent software upgrade includes new code required due to changes that have been made to the GPS system. You can download the software for free from the Northstar web site but it requires a loader cable, power supply and a Windows based PC to perform the update. Most Noprthstar dealers know how to do this but they will charge for their time. The GPS antenna should be mounted where it has a 360 degree uninhibited view of the sky right down to the horizon to get best performance. Basicially any conductive material including pigmented paint, tinted glass or wet canvas can block the signal. Inspect the GPS coaxial cable and it's connections for any signs of corrosion or contamination. Sometimes just removing and reinstalling the connections is enough to remove contamination and get better performance. If in doubt concerning the coax and it's connections, temporaily substitute a new coax assy by-passing the existing cable to see if this makes a difference. You can monitor changes from the GPS status page. See the user manual for information concerning how to understand the numbers being presented. You should be tracking at least 4 SATs with signal levels higher than 30. Generally 95% of all GPS signal issues are related to the coax or its connections.
