ahhhhh!
Now that's a different story. Yes, you can go to the advanced diagnostic mode. It sounds like your post may be bad. It's a magnetic electrical device that has to make contact with your lanyard to read the ROM chip inside for the mpem to recognize it. If it's the wrong one, it will give you one long beep.
With your lanyard off the post, push the start stop button 5 times. You should hear a long beep and a short beep. Then, put the key on the post. If it starts, then all is fine. If you get a series of beeps, count them. Re-post and tell us what you got.
Never clean this electrical connection with a solvent or use die-electric grease. You can use warm, soapy water to clean the lanyard and post. Teh year of your ski makes me believe your post is bad. Not to expensive to replace and is a simple fix you can do. Mine went out on my 1997 last year with the same symptoms that your having. I replaced the post and haven't had a problem again.
Let me know what you get in the advanced diagnostic mode. :cheers:
