Put a new batter in when I purchased the bike a couple of months back, but went to start it the other day and it was dead. So I pulled it out and put it on the charger for a while. Take the bike out for a ride and I noticed that it seemed a little flat just cruising around, but I blew it off as my imagination. Filled up on gas and was heading home, got into it all the way in 2nd and then I know something was wrong. Power came on too smooth and was noticeably slower than before. Does the computer reset when the batter is removed? I know the trip odometer did, so I'm assuming that the computer did as well. Hard to say if this happened when I first bought the bike, it had been almost 5 years since I'd been on a bike so I took it easy for the first week or so to get used to the bike. I'm wondering if some driving will help it sort itself out. Performance mods, if it matters, are: Buell Race Header, muffler, computer and carbon fiber ham can from American Sport Bike. | ||

You need to replace your voltage regulator. It is EASY to do. One important note on your bike, is that even if it has the volts and amps to run the starter, it may not have enough left over for the FI system and you;ll never get it started. BE SURE to zip tie the connector back on, and use thread lock on the two screws! | ||

oh - and the voltage reg off of a 00 sportster 1200 will fit too. In some locations, it costs less. (Message edited by drfoster on July 07, 2008) | ||

I'll order a voltage reg tomorrow, hopefully that will cure my issues. I'm stiff hoping that the performance will come back as the bike relearns and the afv is set back to wherever it "belongs". | ||

I'm a little confused how was the VR determined to be Bad? Most issues with the FI / charging require a logical approach to solve a dead battery can be caused by several issues the VR may be one 1. are the terminals tight? 2. when running at road speed 2~3 K what is the system voltage? falling off or rising to above 13+V 3. is there any other accessory attached causing a drain? To answer you I don't know for certain if the TPS zero moves with a power down I think not, usualy a short period of riding will sort some issues,[ AFV ] there are a number of possibles In my personal experience its whats hooked up the the computer in the majority of instances is the problem. check the system voltage while running you can do this in the drive way the supposition that the EFI will not work at low voltage is correct the lower limit is not widely known I have to believe that it is below 8~10 volts | ||

..a dead battery can be caused by several issues the VR may be one. In my case when I had those symptoms, the stator was the culprit. It was easy to confirm using the procedure outlined in the service manual. You'll need a multimeter. A cheap one is fine if you don't have one now. |
