My wife has a Lynx L3 which she depends on. The throttle needs adjustment. (Six blinkings of the green light when you turn switch on) . Where can I find instructions on line to adjust the throttle? It is New Years eve and no one is open and there is not a place repair near our town anyway. Please help.

Don,

The complete service manual is available from this link:

In my experience the best way to adjust the throttle pot is to clean it. I usually replace both the throttle potentiometer and speed potentiometer when they fail or they have dead spots. You can carefully remove these components by removing the covers and following the service procedures in the manual. Very carefully take them apart to clean the wiper on the potentiometer with electronic spray contact cleaner (this is not in the service manual; use extreme care and do it delicately). You can adjust the spring tension on the throttle potentiometer with careful bending.
You can try first to zero out the throttle pot by hand and start the scooter to clear the error code. With your left hand adjust the lever left or right and with your right hand turn the scooter on. By trial and error you may be able to get this to work.
In both circumstances you will wind up replacing both components anyway and the fixes I have described are only temporary. Hope this helps.
