2004 GTX supercharged instrument cluster HELP!

[tsidders]

Hi All,
New to the 4 stroke world...Here's my story. I recently acquired a 04 GTX that had a history of sinking. From the looks of the waterline, it appears that it was sunk where the motor was 2/3rds underwater. I was able to get the boat dried out and running and fix the sinking issue( OPAS bellows were torn). I've changed the oil multiple times and it seems to be all good as it fires up instantly and idles well.
1) When I first got it, the DESS would chirp like it should, it no longer does
2)It fires up and runs as it should, but the cluster is dead. I've taken apart the hood and pulled the cluster tested the wiring for continuity, there was a corroded wire under the hood hinge(quick connect red/blue wire) that had been repaired. Now all the wires from the cluster to the MPEM have continuity.
Is there a way to test the cluster to find out if its the problem?
Could it be the MPEM? even though the ski runs?
Any help would be appreciated!
Thanks
Tim

I recently replaced my gauge cluster and used a CandooPro Tool to marry the cluster and reset the maintenance warning. It works great for diagnostics!!!!!!

Is the entire information center dead ?

2005 GTX Manual
Section 06 ELECTRICAL SYSTEM
Subsection 04 (INSTRUMENTS AND ACCESSORIES)
PROCEDURES
Information Center
When there is no display at the information center,
perform the following:
– B.U.D.S. can be used to check its operation.
Look in the Monitoring tab.
– Check fuses.
– Check supply wire (1-23) and ground wire (1-8)
from MPEM.

– Check communication link wires (WHITE/RED
and WHITE/BLACK):
• To quickly check if the communication link is
working, temporarily disconnect a sensor on
the engine to create a fault code. Start the
engine. The information center should dis-
play a fault code when in onboard diagnostic
mode.
• Check if wires are swapped, unconnected or
short circuit.
• One faulty wire will cause a longer delay to
perform the self-test when safety lanyard is
installed.
– If everything tests good, try a new information
center.

If you have 12v and ground to the cluster, it should work by at least doing the power up cycle. Your mpem has no effect on this. The clusters fail frequently especially if they get wet. Beepers fail quite a bit as well. For your ski, the cluster is plug and play so no flashing or marrying required.
