Hi guys have some issues with my 2006 gtx 215 was sat over the winter by the last ownes and not winterised so was left to grow and cause a few issues I replaced the looms for second hand ones as a few went s bit green but still have the same fault the ski will run with no lanyard in the post only way to cut the power once finished being used is to take the two fuses out off the power lead that feeds the ecu. And help or input would be great guys.
 
Sounds like the reed switch in the DESS post may be stuck closed. Get a wiring diagram and meter, undo the connector at the base of the steering column and meter out the wiring to the post. If it is stuck closed then you need to replace the post, not an uncommon failure on a 9 year old machine.
 
This is more than you asked for, but good info.

The Mpem, (Multi Purpose Electronic Module) needs to beep 2 times to let you know it is ready to start. Clean the post and cap with soapy water. Don't use any grease of lubricant on it as it needs a clean connection to make contact. Connect the lanyard to see if it is making a connection. 2 beeps and it's ready to fire up.

Engine start/stop switch verification;
Disconnect the Yellow/Red wire of the start/stop switch. Using an ohmmeter, connect test probes to the Yellow/Red wire and to ground. Measure resistance, it must be an open circuit (switch is normally open). Depress and hold switch, the ohmmeter should read close to “0” ohm.

Safety Lanyard Switch Verification;
If 2 short beeps are not heard when installing the safety lanyard, disconnect the switch wires.
Safety lanyard removed;
connect the test probes to switch Black and Black/Yellow wires. It’s an open circuit, there should be no continuity.
Connect one test probe to the White/Gray wire and the other test probe to the switch terminal. Measure resistance, it should be “0” ohm. Connect one test probe to the Black wire and the other test probe to the switch ring. Measure resistance, it must be close to “0” ohm.
Safety lanyard on switch; connect the probes to switch Black and Black /Yellow wires. Measure resistance, it must be “0” ohm.

Timer Verification;
The timer is integrated into the MPEM. Always confirm that the fuses are in good condition. To confirm operation of timer, remove the safety lanyard from switch. After 5 seconds delay, depress start/stop button once. The timer should stay on for 33 seconds (for example, the gauge(s) will be activated) and than turn off.

DESS codes. It is possiable that you are getting a mixed code.
DESS Codes/ Beeps
2 Short beeps …the engine is ready to start
1 Long beep …no communication to MPEM
4 Short beeps… (on Jet Boats) Shifter is in gear
8 Short beeps…defective MPEM
1 Continual beep…engine over heating


Advanced Self- Diagnostic Mode


By pushing the start/stop button 5 times, you’re putting the DESS in advanced diagnostics. When you have successfully done this, you'll hear 1 short, 1 long beep then, put on the lanyard cap. The engines should start if everything is ok.

2 Short beeps means MPEM can’t read the lanyard cap or it has bad magnet. It could be a bad wire connection at the Lanyard switch.
2 Long beeps means wrong lanyard or bad connection of DESS connection
3 beeps signal the wiring harness of the DESS switch are grounded, or a short circuit somewhere.

You may have a bad connection in your wiring harness, from corrosion. Go through your electrical systems connectors and check for corrosion. Clean them with some contact cleaner, then die-electric grease.

To listen to the codes again start from the beginning.
