2000 GTX Won't turn over

[MrSkins26]

I have a 2000 GTX Millennium with the 961/carbs. 2 Weeks ago I was on the river at full throttle when the wear ring in the impeller decided to eat itself. I was not sure of the problem at first however I was able to quickly ascertain that the propulsion unit was plugged. While troubleshooting in the river I received an Over Temp warning and shut the machine off. I was able to get a tow (at around 3-4 MPH) back to my launch and trailered the machine. I quickly started the machine on the trailer and it ran fine. I have since replaced the wear ring and impeller. I am waiting on the rest of the parts to completely overhaul the propulsion unit.

Here is the newest issue. I cannot get the machine to turn over. When I install the cap on the ESS post, I receive various beeps. Sometimes I get 2 beeps of the same tone, sometimes I get 2 beeps with different tones, sometimes the Info Center will activate and I receive no beeps. When I go to advanced diagnostics, there are times when I receive the proper short and long beep sequence; there are times when there is no audible indication at all. The constant is that the info center always activates and you can cycle through the display.

My personal take is that the ESS post needs replaced. However it could also be the ROM chip in the lanyard, my lanyard is about 4 years old. I have been an aviation mechanic working on helicopters and turbine engines for 25 years. However this little bit of technology has me stumped. Any help would be appreciated.

I found the fix myself

After searching the entire forum, I found only a few things that would help me. From what I read, everything was pointing to the ESS or MPEM as the primary failure point. So today I went out to the machine and started troubleshooting. I started with the obvious things first, battery, cables, fuses. When I realized that the starter fuse was located in the rear electrical box, I decided to check it. When I opened the box, it was obvious that the previous owner has had this machine submerged at least once, something that I was not aware of. I just bought this machine about a month ago. So I removed the entire box from the machine, removed everything out of the box, cleaned it, repaired 2 ground wires, cleaned all of the harness connectors, the starter relay, and put it all back together. Well it now runs just fine. The end result; I will have to replace everything in the box by the end of the season due to corrosion and water damage. Hope this helps.

Good job mrskin. It was sounding like a DESS post or lanyard to me also. This is a classic example of how important checking all the ground wires are. Thanks for the great posts.
