Hey All. I changed the battery in my '99 1100GS a couple weeks ago and ever since then the ABS has been malfunctioning: Lights flash normally when you turn the ignition on, when you pull away you can hear the normal self-test clank but it doesn't stop - just keeps clanking intermittently whilst the ABS lights continue to flash. If you turn off the ABS, everything is fine and it worked perfectly up until I did the battery change. Anybody got any ideas?
