hello to all.
this is one issue that has us going nuts !!!!!!!!!!!!!!

i have 2 06's big dog chopper that belong to me. they are identical.
i have one bike with the cluster and speedo, the whole thing wont light up. everything on the bike workes perfectly. but the damn cluster and speedo , zip !

i proceeded to remove parts off my good bike where all is working :

- speedo, cluster exchanged. all work fine on the good bike.

- harness for the speedo and cluster that goes to under the tank with 2 plugs.., i figured maybe a broken wire on the bad bike, so i removed the harness. i install it with my cluster and speedo connected to the good bike and all works perfectly.

- so i know for a fact that my cluster, the harness goung under the tank with 2 plugs is good .

- next , i take the ehc from the bad bike and install to the good bike, the ehc works great. all work including the cluster and speedo.

- i install he ehc back to the bad bike.

-seems like i have a harness issue ?

i split apart both big bplugs on teh ehc.. no cut wires, nowehere.

- i notices 3 man wires to one of the big plugs, a red that goes straight to the battery + , a green that goes to the starter, and a blue that isnt used and was tie wrapped with another small 2 wire plug together...tucked away.

the red wire has 12 volts from the battery.
my coputer lights up ,
everything works other than the complete cluster .

i notice the cluster harness comes from the other main ehc plug... yet, i have zero broken wires...
the ehc works pefectly and lights up my cluster when i transfer it to my other bike !!!!!!

what else can i swap or test or try ? i am out of ideas..

i will pay someone to walk me through the steps.. i am lost here !

On your bad bike, check the wires on connector back to where the wire ends with an ohm meter. Sounds like you have a wire or pin connector on the bad bike that has broken. disconnect the battery and put one lead on the connector pin or socket. then the other end of your meters lead to the coresponding wire color where it terminates on the bike harness and check for continuity. No continuity bad wire or pin crimp.
