BRAKE FAILURE LIGHT STAY'S ON . 2007-RT1200R

SOURCE: bad battery

Don't rely on on whether the bike will start at a gas station to determine if the charging system is working. Get the multimeter out and do a proper test. Should be getting about 14.5 volts @ around 3K RPM. It's too easy of a test to to just skip. If it is charging then start looking for something else. Was the new battery properly charged to begin with? Loose battery connection? I suppose the GPS could be too much but you said that it was dying last november, so I would suspect something else. P.S. you need a properly charged battery to get an accurate reading for the charging test.

This is normal. Its part of the start up diagnostics where the sensors needs to see the wheels rotate 1 or 2 revolutions to verify proper functioning of the ABS system.

I would check the brake pads first to see if they are worn badly, spent a lot time once learning that will cause ABS lights to flash!
Grounding the middle pin on the ABS diagnostic plug , turn on the ignition and mash both brakes to see if the bulb checker light goes out! Very important, left out of procedure on IBMWR, if the red bulb checker light doesn't go out you have a blown tail light or stop light bulb and the ABS won't reset!
Or you have a bad bulb checker module underneath the seat. If the red light goes out then the ABS lights should go to flashing then push the ABS reset button and hold for slow count of 10 or so. Release and try it. Hope this helps!

Your ABS is off line - this can happen when the battery gets weak or when the wheels spin at different rates while the engine is running. In fact, you can force this error condition to happen while the bike is up on your service (Wunderlich) stand: Turn on the engine, shift into first gear (be careful here). Spin the front tire in the opposite direction of travel. the ABS will come off line and the lights will flash. You generally have to take the bike over to the shop to have this reset, but there is an alternative. There is a company in South Africa called Hex Code that makes a device called the GS-911. You can hook this up to your wiring harness and connect to it with a computer, Windows Mobile device or a Blackberry via Bluetooth. From the software interface, you can reset codes like your ABS error as well as view and log other values. Check out the site: http://www.gs911usa.com/ They have a video showing the whole enchilada. Also, go over to Chromeheads.org and sign up. See you there - my ID is grant111 - send me a PM!
