there is something wrong with my temp gauge it works some times and i got a lot of people saying it could be a electical problem i need some advice

 

well check the connections on the back of the cluster to make sure they are good and clean and then check the connection to the motor, its located on the side of the head bellow the dizzy, its the single wire that plugs in there, also trace the wire to make sure there is no breaks/cuts in it...look in the manual it will probably have so test to run...
