1986 harley fxwg. How do I connect a tach?

SOURCE: lights bulbs in tach and speedo

The tach and speedo are their own separate unit.  There is no changeable light bulb.  You may want to check your light and instrument fuses.  If those are working, I would remove the outer fairing and check the connections to your tach and speedo.

The pink wire goes to the pink eng rpm signal wire coming from the ecm. Go to the stealership and ask 'em to show you where it is.

I'd say that you have an intermittant short somewhere. These are very difficult to find. I'd start at the tail light assembly as most of the time, I've found the shorts in that area, from the seat back to the tail light assembly.

Good Luck
