Optimate help - please!

[earthmover]

I have long since lost the instructions for my Optimate, battery is dead flat on the KTM (don't know why yet ) When I put my booster pack to the battery, all the dash lights on the bike come on as if everything is ok, but when I connect it to the Optimate, none of the "battery condition" lights come on. I connected it to the GS as a check, and the "charge" light comes on as normal.
Anyone?

There's not enough charge in the KTM battery yet.

Cheers for that Tim, I wondered if that was the case, or whether I had fecked something up.
