Last week or so I posted about error codes involving BUS Er, I believe I have that problem corrected, the only thing left is my police tach, and the indicator lamps in the tach still do not work. I checked the fuse panel behind the left saddle bag and they are all o.k.. Does anyone know where the fuse for the FLHP tach is located?

If the lights in the tach are coming on then the tach is trashed. No blown fuse.

The lights in the tach do not come on.

Have you removed the back of the tach and checked the plug? I have seen them wiggle out of the clip. While you are there, check for power on the orange wire and continuity on the black wire to ground. Pink should be the tach signal wire and the others are for the indicator lights. There should also be a Duetsch plug that the harness from the tach runs into.
Many years ago, while I was still in training, one of the teachers told me that "Every electrical problem can be found by tracing the entire circuit from the positive battery post, to the item in question and back to the negative battery post" So far I have never been able to prove him wrong.
