Question about 2008 BMW R 1200 RT
Posted by Anonymous on
Hi Anonymous, in order to check out any main system electrical circuit, you have to start with a fully charged battery 12.5 volts or better, and be able to pass a load test if necessary.
1. Check battery terminals for damage or corrosion, check battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
2. Check the voltage drop at the battery when you hit the starter button, anything below 9 volts you might have a faulty battery.
3. Check voltage at the battery with the bike running at 3,600 RPM should be 14.3 to 14.7 volts. If you are not getting these numbers, you might have a faulty voltage regulator.
4. Make sure voltage regulator is grounded and functioning properly, watch the video below on how to test a voltage regulator.
5. Unplug the connector to the alternator and hook your multimeter leads to the alternator (pin/socket selection does not matter) set the multimeter to AC volts, at an idle the meter should read 16 to 20 volts AC. at 2,000 RPM 32 to 40 AC volts, 3,000 RPM 48 to 60 AC volts. If you are not getting these numbers, you may have a faulty rotor, follow step 6
6. Set the multimeter to OHM'S, connect one lead to the alternator (any pin/socket) and the other to a ground, the meter should read infinity. Connect both leads to the alternator meter should read 0.1 to 0.2 OHM'S. If you are not getting these numbers, you have a bad stator.
7. Check all wiring in the charging circuit for worn or chaffed spots and all wiring connectors in the circuit for corroded, broken, or loose pins/sockets, which is the # 1 offender.

There is a simple way to fix it as I've discovered. Start your bike, if lights are flashing ride for a mile or two applying the rear brake a few times. Stop the bike and place on centre stand. switch off motor then restart. Your flashing lights should have gone. Why the flashing happens is if you ride and use your rear brake rarely and then your bike sits for a day or two without use your rear brake assembly fully retracts, ie pads away from disc and ABS gizzmos inactive. The ABS sensor unit then reports extended non use pattern to the onboard 'brain' which activates the warning mode of flashing lights. This has worked for me several times over the last 5 years when its occured. Full ABS operations return. Tried it on a mates bike and it fixed same problem on his.
