Paul, don't give up just yet!....your just getting started on the learning curve. Have a little patience.
You said you have nothing, correct? And now, your also saying the batter has a good charge and the load test is good.
So that leaves us in only one area that can be the problem. The DESS cap and/or post.
Let me know if this is correct. When you put your cap on, you get nothing? No beeps, no gages, nothting? O.K..........one more question. Do you know how to use a multi meter? If so, we can do a ohm test on the DESS post.
It's obvious that your not making a connection. Because, even if the mpem is bad, there are a set of beeps to confirm that you have a problem. Even if you try to start the ski with a different DESS lanyard, you'll have beeps. So the problem is that your power system in the lanyard is not being enegized. The likely problem is going to be in the post if you've used a spare key and got the same results.
I'll look in the manual and get the info as to what your results should be for that test.....
O.K.,Paul, I got the test for your post. If you don't know how to read a multi meter, you've got to know an electrician friend that can help you. A shop will charge you out the yang-yang to trouble shoot this. You'll need to find the plug on the bottom end of your post and undo it. If it's easier, you can remove it. For me, it was easier to remove. A pwc, I'm not to sure. But you'll need to get to the 3 wires.
Test 1: with the cap off, put the tester wires on the black wire and the black/yellow wire. The circuit should show "open" at 68*F.
Test 2: with the cap off, put the tester wires on the grey to the post terminal (the little metal button on top of the post). The circuit should show a reading close to 0.
Test 3: with the cap off, put the tester wires on the black wire to the post ring (the little metal ring around the post). The circuit should show a reading close to 0.
Test 4: with the key ON the post, put the tester wires on the black wire and the black/yellow wire. The circuit should show a reading close to 0.
There you have it. Let us know what the results of this test is, then we'll go from there. Have a little patience, it may save you a bundle.........
