Maintenance Charging

Hi - I have a 2017 T120, about to store for winter. Now, a question about maintenance charging; I have an Optimate 4 charger, comes with two different types of attachment cables, one a crocodile-clip type, the other with O-ring type screw-on connector, I guess either one will work. Thing is though, do I disconnect the battery from the bike completely, or can I charge it with the batter connected??

Thanks in advance guys!

 

Thanks mate, appreciate the quick answer.

 

Further question; the Optimate has 2 modes, STANDARD and CAN-BUS. I assume the CAN-BUS mode?

 

think I'll stick to torque wrenches
Gawd elp us

 

I've twice attempted to fit my Oxford optimiser to my new Bobber but the in line fuse keeps blowing. I bought a new in line fuse cable but same thing. I attached the red clip to the live terminal and the black clip to the battery earth connected to the bike frame. appreciate some answers / advice. thanks guys

 

New lead mate. As I said, connected red clip to red batt terminal and black clip to the earth strap connected to bike body. ( Not battery earth terminal) . never had this happen before, fitted to many previous bike

 

Think about it ! One plausible reason could be that IF the system is POSITIVE ground you are connecting the charger positive to the same point (frame) and shorting the charger out ?
I presume that the charger fuse is blowing ?
My best guess so far !
