Had a flat battery last fall in my 2007 XT660R. Don�t know if it was due to forgetting to switch off all accessories or if it had been badly charged lately, or maybe a combination. The bike didn't charge properly after jump-starting it and died on me a couple of miles later. The battery charged just fine after hauling it back home, and now starts good. Battery is a Motobatt AGM <2 years and doesn't loose charge in a drastic way when left alone disconnected (went from 12,95V fully charged to 12,73V in about 1,5 weeks). No current leakage when measuring Amps between plus pole with ignition off.

BUT my regulator/rectifier measures 13,99V @ 5000 RPM over the poles. Never goes past 14,0V. Specs says its shall be 14,1-14,9V. I guess its starting to break down after 16000 km, and I want to replace it before this summers touring.

Has anyone else converted to a MOSFET R/R? Only find information about XT660Z Those crappy OEM ones will die on me sooner or later again.
