thanks for reply, but i dont even have a display on the screen, there is power in the wires at the back of it but no power on the speedo at all, it wont turn onBe sure the plastic tube is connected to the rear and its clear all the way back to the engine. If it is, then make sure the hole on the front of the gear housing is clear.
If its not even reading 0, then the gauge may be kaput.
