  2. No current is good, except... What was the source of the arcing between the tank and the line? Did you test with the tank down? With the meter set to continuity, check from the spot you used from the tank to ground. Make sure there is continuity so you know that you have a good connection on the tank. When you had this problem before were there any other sources of power connected, like to accessories? Did you have a tank bag or something pressing down on the tank? Any circumstances different that may effect the electrical system? This is why electrical problems can be such a bear. At any rate, I suggest adding the extra grounds. It's easy, and our bikes seem to need it.
  3. "I need a VERY simple explanation of how to check the possible current through the tank stuff you suggested." Set the meter to volts dc. Check a couple of known things as a test and practice. For instance, put the red lead on the batt pos and the black lead on the batt neg to get battery voltage. You should see 12v + or - about 1.5. Switch the leads and you should see the same voltage with a (-) . With the red lead on the pos terminal of the battery, put the black lead to various metal surfaces on the bike. This will show you what is a good ground. You should see very close to battery voltage with a good ground. This is because the battery negative terminal is grounded to the frame. Then, put one lead on the tank where it was touching the line, and the other end to ground as just determined. (The neg post of the batt, or any bare metal part on the frame, engine, etc.) The lead on the tank needs to touch bare metal as was present when you found the problem. Do this first with the key off. You should see no voltage. Next test the same with the key on and run switch to "run". Finally, test with the bike running. You should not see voltage during any of these tests, although I suspect you may after hearing your problem description. If you see a reading it means there is a short in/at the tank. This means that a power source (to the fuel pump, sensor, etc.) is getting from the wire or the component to the tank itself. That electricity will seek the path of least resistance, which apparently it found to your oil line (or whatever line was rubbed through.) I would do these checks before you add the new grounds, if you haven't already done them. So, what do you do if there is voltage through the tank? Unplug the connections to the tank one at a time until voltage goes away to find the source. Good luck; post again if you run into questions. MQ
  4. While you're still messing with this, check voltage and resistance through the tank. I think you need to find the source of voltage to your tank, as a short there sounds like your problem. (Or, a problem, at least.) As BR has emphasized, you should not have power running through the tank. Simply preventing it from going to the frame/oil line or wherever, is masking the problem, not solving it. Also, I agree that the extra grounds on both sides of the blue connector are a good idea. Good luck.
  5. ROD, Do you have to take the sliders off to get the fairings off?
