Speedometer issues

[BLnews78]

Currently I've gone through three speedometers on my 95' XL1200 sportster. the speedometers just randomly stop working. i am wondering if it is a wiring issue. if you have an thoughts or solutions... your responses are appreciated.

Are you sure it's the speedo and not the pickup on the transmission? They both have similar symptoms.

Three speedo's is just too freakish to be true. It has to be something else.
