Towelie, Great job on the pics. I also had a screw fall down into the bottom of the down tube, and ended up flipping the bike over to get it out. No water in there, but we haven't had rain in weeks, so no surprise. For anyone doing the mod, I suggest maybe wadding up a piece of paper and stuffing the hole before removing the screws. Funny thing is when I flipped the bike to get the screw out, it almost slid into a similar hole in the top of the down tube when it was upside down, but I caught it first, with one hand, while holding the 50 lb bike with the other. There were some swearing going on for sure. LOL.
GARN, if you want to know the details, pick up the phone and talk to S604. They were very helpful explaining it to me. I'm hesitant to try to explain the problem because you might have questions I didn't think to ask, but in the mean time, I'll tell you what I know.
The problem isn't a phantom current problem because the display shows decreasing battery level (for me 1 bar each day) while the voltage of the pack (measured at the output port) remains steady. So the pack is not draining, either on the bike or off. This battery is pretty advanced. It has 5 pins where most low to mid priced bikes have 2. Besides the 2 big power pins, there are three smaller pins which carry other information back and forth across the battery interface. I believe this to be an e-bus interface, but this is just conjecture on my part, so I'll stop there. Anyway, for whatever reason, S604 thinks the bike is constantly sending a configure signal across that green wire to the pack when it really should just do that once. This gives the appearance that the pack is draining (annoying to us users), but not only that, the controller and display may actually act differently if it thinks the pack is low. This is all chronicled in this giant thread somewhere, but this is the readers digest version.
Incidentally, I don't know if others have discovered an annoying little bug. It's so small I never mentioned it, but I'm sure you have seen it too since I suspect it's related. For a few hours after I got the bike, I struggled to turn it off. The directions say just hold the the power button for 2 seconds and it will turn off. Mine didn't. After much trial and error I figured out the correct sequence of turning it off was a quick tap of the power button and then a two second hold. After this fix, it no longer requires the tap and then hold. Just hold it and it will turn off like the instructions say. Whew, much better! Bonus fix.
Today my pack is still showing yesterdays reading, and has not dropped it's erroneous 10 percent, so I am cautiously optimistic that this fix works. Will report again tomorrow.
