The weekend before last, I re-commissioned the V11 after the long long winter layup. I've been looking after the battery indoors and keeping it topped up for several months with a Gel Battery maintenance gizmo (Oxford Maximiser). On reconnection to the negative terminal I thought I saw a bit of a spark so I tested and it happened again. Maybe I should have looked further but I carried on and the bike ran fine and kept charge, although as a matter of routine I keep it plugged into the Maximiser. Today I noticed that Relay 3 was a bit warm fter standing for some time, and tested across the terminals getting a small voltage when the ignition was off and the run switch off. With the run switch on the voltage dropped to 0. I decided to follow up and poring over Kiwi_Roy's worthy diagram I ran through the tests and the tests all seemed to give the right readings. When I disconnected the battery measuring current running into the battery with the ignition off... 12-13 mA. Looking at other posts on the forum there have been some about the current drain from post 17 on the ECU e.g. Battery draining through ECU. These suggest 0.076A is normal so maybe 0.013A is not so bad. I get this arcing even with all the fuses pulled so I kind of suspect something else is awry, insulation breaking down somewhere or something and don't want to push it further. I'm most concerned about wrecking the ECU. So does sparking when connecting the battery bode ill or not? My battery maintenance regime seems to have kept the battery in good fettle but I have a sneaking feeling that if I go away on a long trip I'll find it flat one day. Advice gratefully received. AndyH
