On the way to the office this morning, my speedo bounced from current speed to 0 and back up to speed about 4-5 times. It did not bounce multiple times just once and it did it 4-5 seperate times. The tach did the same but about 3-4 times. I then noticed my volt gage drop straight to 0. It wasn't a slow decent it dropped, would hold a moment and come back up. I got the office and turned it off and cranked again. It started but with effort. I noticed all the gagues worked as should and I took off for a drive. I drove about 3 miles and eveything stayed solid and normal. What the hell???? I have an '02 ED Classic with no upgrades and a battery that's not a month old.
Try checking your main harness connections, cleaning them with electrical contact cleaner and the putting a dielectric solution on them before you reconnect them. I don't know where you live, how often you wash your bike, etc, but electrical connections can get dirty, even when sealed.
I would check battery connections first. Then check all the rest. A friend of mine had the same thing & his connections to the battery was not even finger thight. His died going down the interstate. All of a sudden he had no lights, I looked back & he was just coasting along the side of the road. His bike coasted a long way, up to where I had stopped. Tighten the battery connection with a wrench this time and he road the rest of the day. He went over the whole bike when he got home. Found nothing else loose.
The bike never died with the erratic guages. It kept running. It did try to cut out when I came to the first stop light; I just gave it more gas. The headlight dimmed a lot, but the spotlights stayed strong........weird...... At lunch, I went out and it fired right up like a champ. The guages were strong and no fluctuation. I will check the connections tonight when I get home. If I find nothing there, what else should I consider?
I found my positive connection to be less than a quarter turn loose. It was still tight, but looser (sp) than it was. Tightened it and all still seems to be fine........
