I have a new battery, good grounds, good connections and yet the trip-ometers and the clock keep resetting to "0" when the bike sets for more than 24 hours. I checked the KV, there are a few threads about the problem, but nobody came back to insert the solution or even if they got it to work. It can't drive me crazy, other things have seen to that, but it sure is annoying. Please don't recommend that I clean the terminals, charge or replace the battery. That would be so redundant doing that over some more again .  | ||

There must be a circuit that stays alive all the time... Does the parking light work? I was messing around with my battery today and noticed that if I disconnected the cables for a few minutes, it would arc a little when I reconnected it like it was charging a cap in there somewhere. Does yours also do this? I think that's normal behavior. | ||

There has to be a small reserve of power that keeps the memory stuff alive. I guess I will R&I all of my fuses and plugs again. But really, no one has had or resolved this problem before?  | ||
| Natexlh1000 |
It could be a crummy contact in the harness. I don't have a diagram, otherwise, I would love to check it out for you. | ||
| Etennuly |
I appreciate that. There have been a few people reporting the same problem over some time period in the KV, but no resolution posted that I could find. | ||

This sounds similar to a BMW automotive problem where the on board computer will go out because the battery that is charged while running will eventually go bad. The dealer will replace the computer for mucho cash but you can solder in a new battery for mucho cheaper! Check the wiring diagram see if there is something on the board in the dash that could have failed. I don't know what Buell uses here, it's just a thought. | ||

Does the battery actually drain to the point of causing a struggling start? If not, it may be similar to a problem I had early on with my '06 where I started to lose the trip meters and clock settings intermittently and it wasn't obvious what the issue was at the time. I eventually traced it to a broken wire in a splice that connects the backup power to the instruments to the power wire that goes to the ignition switch. This splice is located in the main loom right where the loom goes through the loom guide at the front of the steering head. The splice itself is covered by heatshrink that is glue-lined so when the wire actually breaks it is held in place quite securely and in my case would 'make and break' contact when I turned the handlebars from lock to lock. The original guides had the loom follow quite a small radius 'S' bend but this was changed with the loom guide that was introduced in later builds. It may have absolutely nothing to do with your issue but then again...... I am currently away from home but if you need any further pictures / repair details I will be back next week and will have access to my home computer. | ||

I had a wire break in that loom when the bike was about 6 months old. I loosened the harness so that it cannot be pulled too tight, but I haven't revisited that area. I will give it a look. Mine also broke the ground wire ends off at the steering head, but that repair is still good. It does not drain the battery no matter how long it sits. | ||

A question.... Is it zero when you turn the key on or after you start it? | ||
| Etennuly |
When the key is inserted and turned to on, before cranking the engine. | ||

hmmm that's a stumper, almost seems like an internal hold-up battery puking out. I think I am tearing into my 'dash' this weekend Vern...let you know what I find. This may not be much of a diagnostic (since your batt is ok) but if you leave the battery tender on overnight, does it do the same thing? | ||
| Etennuly |
I don't have a tender, but I do have a charger. Voltage drop in new battery is not an issue, it was in the old battery though. Does the gage unit have a reserve battery or a capacitor of some sort that keeps them going? Or does it just work off the main battery. I know the power required to maintain the information is almost nothing. | ||
| Sekalilgai |
Vern it's a crappy weather looking weekend here so I'll be digging into the bike ...uhm preventative maintenance that is. I'll let you know what I find...the service manual should shed light as to if continuous 12V is supplied to the gauge cluster. Ken | ||
| Ry329 |
Gauge cluster is powered by the main battery. If you unplug the cluster clock & trip meter reset.. | ||
| Sekalilgai |
ya..just confirmed that ...silly me. Looking over the schematics, it looks like the continuous 12 powering the gauge cluster makes two stops between the battery and it. The two fuses 'battery' and 'key sw' are in-line. The ground looks to be shared with the ECU. I started poking around my harness and haven't found any frayed wires yet and what little jiggle tests I could do haven't induced the problem. From your description though, it happens when the bike is parked so I suspect it may not be vibration/shake induced bad connection. Will keep looking....

Did you figure it out?????? I wonder about that new battery | ||
| Xbimmer |
I just installed a battery like his and it's been great, no starting hesitation or clock/tripmeter stuff like I was getting. My next project is tackling the erratic tach sweeping. I've narrowed it down now to a wiring problem under the flyscreen. Perhaps Etennuly's problem lies in there in the area Rays points out, I'm thinking that's what's going on with mine. | ||
| Etennuly |
The new battery is great! It holds above 12.7v even after sitting for a week. Starts the bike better than ever. It does not drop below 10.3v while cranking. I guess I need to unwrap the steering head harness again. No big deal, just gotta find some unused time. | ||
| Lost_in_ohio |
The oreilly just opened down the street from me. That sounds like the battery for me. | ||
| Etennuly |
It hasn't run in a few days. Fired it up last night and the meters were still there and the clock held. So when I get a chance I will be checking ground and such. | ||

I think Radio Shack may still sell a little device that plugs into the cigarette lighter and a 9v radio battery. I used it when working on my cars and it keeps the memory set in the stereo and clock when doing battery removal or disconnects. I know its a band aid but it may help pinpoint the problem...Just a thought |
