Optimate 3 indications

[Godders]

My Optimate has started to indicate that it's on permanent charge and when I turn the power off with it still connected to the 748 it indicates desulfate. Anybody seen this before or have any idea what it's trying to tell me??

disconnect it then reconnect again.
desulphate means it is trying to desulphate the battery - as in run it down to then recharge it.

Cheers AK, I'll give it a try.

you must disconnct both the battery and the mains, then reconnect both and see what the charger is doing then.
its might just be a glitch with the charger
