12.8 is good. Is that the voltage that it stays at when you disconnect your Optimiser?
If it drops below that (or below 12.6v to be more accurate) - then your battery is goosed and it is your Optimizer that is propping it up.
Thanks for the reply, after 5 mins off charge it jumps up to around 14 v and 0.22amps so I assume this means it is having to give it a boost, so this means the battery is shagged
Also when I turn the key it drops to 12.5v/12.4v and 0.81amps hence the not starting!
I do apologise to the OP for hi jacking the thread with my owns problems!
