Charging Issue

On a 2006 DL1000 what is the highest voltage i should be seeing at 4 or 5000 RPM? My bike is showing in the low 15's. The battery has been dropping down to 10 or 11 volts after riding 2 to 3 hrs straight and will not start after that. Everything has been checked and rechecked and all the numbers are right and there is no draw on the battery from any aftermarket products. Could the regulator be bad? The bike only has 7000 original miles also.
Thanks.

13.5 - 14.5 is the norm, no more. I would say that the regulator is at fault, however the stators are known to fail and in your case I would say it's well worth investigating the output of each phase to ensure everything is as it should be, the low battery voltage is odd given the high charge voltage you stated.

The battery could also be done, so may as well double check that too.

It's not yellow, it's "YELLOW!!!!"

I would advise three checks: the battery, the R/R and the stator. Take the battery to Advance Auto or its equivalent in your area and have them do a load test. Unlikely it is the battery, but it may have been damaged if the 15 volts is a correct reading. If the battery is dead, they'll charge it and then test it. For the stator and the R/R tests, there are multiple threads here and lots of Utube videos. These tests are easy with your multi-meter.

You mention that "Everything has been checked and rechecked and all the numbers are right"... but I'm not sure what you mean by that.

On that bike there is a huge chance the magnets have moved this will give unusual readings.

What are your readings at other RPM's ?

When testing for voltage you should also test for AC volts at the battery, if you find AC volts the regulator has had better days.
