Title: New battery messes up speedometer
Post by: Verlager on May 06, 2010, 06:42:38 AM
I bought a 2006 GrandVista. I just replaced the battery with an Interstate battery shown here http://www.interstatebatteries.com/cs_eStore/Products/RT/PID-FAYTX12(MotorCycles).aspx?dsNavigation=Ntk~SearchGroup|FAYTX12|3|,Ny~True,Ntpc~Disabled,Ns~product+Type|101|1|&Title=Cycle-Tron+Plus+-+180+CCA+-+10+AH (http://www.interstatebatteries.com/cs_eStore/Products/RT/PID-FAYTX12(MotorCycles).aspx?dsNavigation=Ntk~SearchGroup|FAYTX12|3|,Ny~True,Ntpc~Disabled,Ns~product+Type|101|1|&Title=Cycle-Tron+Plus+-+180+CCA+-+10+AH)

The problem is that the speedometer is now reading false speeds. I'm going 40 MPH by my reckoning and the speedometer reads 5-11 MPH.

Is there something special about Kymco batteries? Why doesn't this new Interstate battery work?

It's not the battery. There is a reset/mode switch on the instrument cluster. The owners manual has all the details. http://kymcoforum.com/index.php?topic=1689.0 (http://kymcoforum.com/index.php?topic=1689.0)   this page has the link for your service manual also.

There is no way, according to Kymco dealer tech support, to reset the digital instrument panel. I think I am looking at an expensive computer repair bill, unless someone has a way to clear and reset the panel. I will try replacing the battery next week.

There is a mode button on the instrument panel but no reset button.

Have you tried to disconnect and reconnect the battery?  I'd at least try that.  My Xciting 500 instruments reset themselves whenever this is done.

Took it to the dealer. He said I needed a new sensor. Cost $20.
