Battery/computer question

Is there anything special to disconnect the battery and reconnecting (for a wiring install for example). I thought I read something somewhere about the computer not booting up correctly or you had to switch the ignition when you reconnected the battery.

Anyone? Thanks.

Long day tomorrow to get home from work but I'll check that darn rear tire for air and hopefully just hit the road for a while. Nothing shakes off work like a good bike ride.

If the battery has been disconnected for 10-15 minutes or longer, you need to reset the throttle body limits.

After connecting the battery, turn the key on but don't start the bike. Then turn the throttle full open, then full closed twice. Then turn the key off.

Now you can turn the key back on and start the bike. It may run a little rough for a while until the computer relearns things, but that should take care of you.

Some people see the gas tank as half empty. Some see it as half full. All I care is that I know where the next tankful is coming from...

All you need to do is reset the throttle position sensor after reconnecting the battery. After the first time you turn on the key, fully turn the throttle to wide open. The "SET" light will illuminate on the speedometer to indicate the TPS has been calibrated. I've read several times here on the forum that the throttle should be opened 2 times but the "SET" light only illuminates the first time making me doubt whether once isn't enough. Two times can't hurt, though.

Added in edit: Looks like Meese and I started typing at the same time but he beat me!

Thanks gang, glad I asked! Pretty sure this isn't in the owner's manual.

No, it isn't in the manual, and for some reason the dealers don't seem to do it after disconnecting the battery and working on the bike. My bike ran like crap after the dealer replaced the airbox, until I got it home, disconnected the battery, waited for about 30 minutes, reconnected the battery, and did a TPS reset.

Interesting. We'd always heard two times on the LT site. I can see how the GT might only need once, especially if there is a lighted indicator to confirm it.

I don't think the SET light is a confirmation of the TPS reset, I believe that is only for the computer checks for the cruise control.

I did a TPS reset yesterday like this - turned on the key, rolled on the throttle, rolled off. The timing was perfect and the SET light lit up when I did it. Turn the key off/on and just watch - the SET light goes on during the pre-checks, so I think it's just good timing/coincidence.
