Battery Terminals

I took the battery off last night and noticed that the positive and negative were the opposite way round to the hand book

I realise it probably doesn't matter a damn but I had a non standard battery fitted under warranty and was wondering if the dealer changed the wiring routing. My 999 has the positive uppermost.

Whats the norm?

It really DOES MATTER!!!!

Your bike should be connected with a negative earth on it. If you put it back the wrong way round you could blow the entire CPU, etc.

Put the battery back exactly as you found it

Agreed. The replacement battery must have the terminals in the opposite place to the original.

I never intended to connect the red cable to negative, etc. and the battery can only go back in one position. What I meant was, that as long as the red cable connects to the positive terminal and the black cable connects to the negative terminal, it doesn't matter at which end of the battery the positive terminal sits

Must it? Or is the hand book wrong?

No. I don't see how you can do that on the 999/749 series as the battery and cables all sit enclosed in a large plastic moulding.

The ability of mechanics to totally screw things up should not be underestimated...

I found that the cables on the 749 were really short so it was hard to get the battery out. I would be very surprised if they could be transposed, although I guess some rerouting could be done. If I recall, the negative (earth) is at the bottom and postive at the top.

Sorry, the pic was actually of the PC3 placement, but happened to include most of the battery too.

Ah, ok I see what you mean now.

I'm sure it could be done *if* you took the battery cover etc, off and rerouted the wires, maybe? Either that or Glenn has bought a dodgy bike
