hey guys im having a issue with my water temp gauge when i turn the car on the gauge will flick near the cold spot witch is near 100F and when the car is warm the gauge dosnt move ive wired the gauge up using the factory ground wire. spliced a wire to the ign and ran a wire from the gauge to the sender anyone had a similar issue could it be the size of wiring im running bad ground point

are you using a sender that came with the gauge or the factory sender?

autometer one. i think i worked it out. i need to run a ground wire from the sender
