first off I've searched already.I changed handle bars and now I have no tbw,got a new twist sensor with no plugs til under fairing and still the same,start bike up,everything works,then twist throttle,works good twice than nothing just idle,shut bike off,restart again and same works twice then nothing.need help want to ride!

 

Try checking for codes. TCA may need cleaning. The pins can get corroded. Otherwise, you messed something up when changing the bars and miswired it.

 

I've got a manual but can't find checking codes,does anything else control tbw in the other switches?

 

1- Turn Ignition switch to OFF & Run/Stop switch is to Run.

2- Push odometer reset button in & hold.

3- Turn ignition switch to Ignition and release odometer reset button. Background lighting should illuminate, speedometer needle should sweep its full range and indicator lamps (battery, security, low fuel, check engine and cruise) should illuminate. The word "diag" should then appear.

4 - Push the odometer reset button once and you will see the selection menu "PSSPt" with the first P flashing.

5 - Each letter represents an area of the diagnostics module. The module that is flashing is the one you are going to check. To move from one letter (module) to the next, you push the odometer reset button one time. (from P to S to SP to t and back to P, etc.)
P = ECM/ICM (Electronic Control Module [EFI] / Ignition Control Module [Carbureted])
S = TSM/TSSM (Turn Signal/ Turn Signal Security Module)
SP = speedometer
T = tachometer

6 - To get the DTC within an area of diagnostics, push and hold the odometer reset button in for 5 seconds and release. If there are any DTC's the code will be displayed or the word "none" will appear if there are no DTC's. Push the odometer reset button again to view additional codes if they exist.

7 - Record the codes.

8 - If DTC's are not to be cleared, Press and release the odometer reset button. Part number of module will be displayed.
NOTE: To determine if a code is current or historic, clear the displayed code by pushing in and holding the odometer reset button ( longer than 5 seconds) until 'clear' comes up. Release the odometer reset button. Turn OFF the ignition switch. Run your bike and shut it down then recheck the DTC's again by repeating steps 1 to 9. If the code is current it will reappear.

9. Press and release the odometer reset button to continue to the next module.

10. Turn Ignition switch to OFF.

 

thanks,I'll try the code stuff.

 

ok,got codes p1510,p2138,when I got the new twist grip it came with a yellow wire loam with red,white,black wires,and a black wire loam with red,white,black wires,no green connector gos into a black connector anybody know how to wire this to bottom connector,( to what what color wires)oh and a set of 1 white and 1 black wire which I thought was a grip warmer and taped off.

 

The two wires taped are for the grip heaters.If you bought this new the instructions are really easy to do .I just finished mine on a 08 sg works fine.If you still need the colors i can send them after work today.

 

new day ,fresh mind, to the garage I go
