hi guys, ever since i bought my rig , the tacho plays up a little bit , where abouts on the TD42 is the sensor for the tacho ? so i can have a look , or it may be something else , check the link to a vid of the problem

Have you had a good look at that vid , looks like something is loose as every time you hit a bump it dropped
Bad earth ?? I'll try to find in my work shop manual, found every thing else but nothing on the tacho. couldn't even tell you where fuse is

Can't get your hand up the back and have a bit of a feel for anything loose
