| A battery problem?
My 916 has been getting difficult to start when warm (i.e. after being parked up for a while after a run) - very sluggish turnover. The battery looks like the original, so I thought I'd replace it.
I got a new one, put it in and connected the Optimate (III) as instructed. The red "Desulphate" light came on, followed eventually by the "Weak" light. I took the bike for a run last weekend, difficult to start as ever when warm.
This didn't seem right, so I took the battery back and got a replacement. Installed it as before; this time the "Charge" light came on, then the "Weak" light again...
It seems unlikely (or very unlucky) to get two duff batteries. Do Optimates go wrong? I did put the old battery in while I exchanged the new one - got the "Green" light on the charger then.
TIA
