Reconnected battery - tacho sweep!!??

[Jools'SV Now]

Not enuf juice in the battery to turn her over yesterday - not used a while.

Took out battery and recharged for a bit and reconnected.

when I turned the key in the ignition, the rev counter needle swept upto 7k and back down again.

anyone know what this means??:confused:

ta in advance

BTW it still didn't have enuf juice as the charge wasn't for long enuf - is now fully charged though:smt045

Yes.
It's automatically done when reconnecting the battery if it has been disconnected for more than 40 seconds (according to the service manual).
My K7 did it when I connected the bike's battery for the first time a couple months ago.

My Bandit used to do this every time I turned the ingnition on. Both dials all the way round and back down again. Quirky and quite cool for the first two times I saw it. :lol:

My kwak too.

When I had a knackered battery my speedo indicated 183mph for a few miles! Then it stopped working and I got a lift home in a van.

Daytona does it every start up.

Maybe the battery was once in an er6??
