Tuono electrical issue... surprise, surprise.
Last Saturday, middle of the first ride of the season, the bike wouldn?t turn over. Just click. Bump started it and got home. Took it apart and noticed the negative battery terminal was highly corroded. So, I cleaned it all off and improved the connection to the battery post. Hit the ignition. Roared to life.
So I took it out the next day. Rode for maybe 100 miles. Stopped to take a break. Then went to leave, bike would turn over cleanly, but not start. I decided to try bump starting it and it fired up, then died immediately. Next twenty minutes tried maybe 5 times and it just turns over. While waiting for a tow, I tried a couple more times, then I lost power to the dash and the whole bike. But the battery wasn't dead. Just no power.
So, it's put it on a trickle charger for a week, take battery to service shop and battery tested perfectly normal. Reinstall the battery and start checking electrical connections. Check a few, then try the key. No dash lights. Try as few more connections, try the key. No dash lights. Then I follow the ground wire from the battery to the right side of the rear cylinder. I just push on it a little, trying to feel how much corrosion is there, and there's not much. Seems clean. But I try the key again, and the dash lights come on.. So....it seems there's a problem with the ground connection....at the very least. But the fuel pump isn't priming, and it's still not starting.
My guess, it's a bad ground connection. I'm planning to add a ground wire to the frame from the negative terminal, and cleaning the existing ground connection. Possibly replacing the battery cables with the John Walker mod. And I?m going to bite the bullet and finally do the brown connector mod. Only 8k miles on the bike, but I suppose it?s about time.
Any other suggestions or ideas? That?s about as good as I can tell from the reading I?ve done here. If you guys have any other links that could point me in the right direction, I?d appreciate it.
