I have a 06 R1200 RT with the CANBUS. I wnat to hard wire the leads for my Deltran Battery Tender Plus directly to the battery terminals and then connect the feed from the Battery Tender to the leads and charge the battery in the bike without removing the battery from the bike or disconnecting the bike electrics from the battery.
Anyone doing this without consequence? The BMW CANBUS charger is a bit pricy and useless on anything besides the Beemer.
The manual says to disconnect the battery before charging to avoid any damage to the CANBUS, but I cannot understand how this could happen with the ignition off. Is the CANBUS live even with the ignition OFF?
