This works on the '06 + up models.....
Your fuse(s) are under the seat by the battery (I think). IF you find it - pull the 30amp accessory fuse. THEN remove the battery cables. Wait 5 min. Re-connect the battery and put the fuse back in.
You need to "wipe" the ECM memory to re-set the pod display. This method seems to solve most blank pod problems. If not - check your wiring harness up under the pod to ensure it plugged in to the gauge, and while your at it check ALL your wires running up the front of the handlebars/steering post for any wire chafe'n.
Hope this helps....good luck.
