SportTouringCZ Posted March 17, 2019 Share Posted March 17, 2019 Hi guys, My VFR has been perfect so far but today it left me stranded for the first time. Situation: I have the VFRness installed. 13.4V at idle is my charging current. I have done about 150kms after winter break. (trouble free). Today I washed the VFR and some symptoms appeared. 1) When I turned the blinker on speedo and tach died for a second (dead while the bulb of blinker was on for the first time) 2) Speedo and tach dead when I turned the blinker on every time the bulb turned on. 3) Speedo and tach dead every time I pressed brakes. - I stopped at the side of the road. VFR refused to start again. Pump primed but starter didn't move after the button press. After I pressed the starter button pump primed again as if I turned the ignition on and off. 4) My friend came to rescue me with a new battery. (12V-12Ah insted of 12V-10ah) bike started right away and finished the 12 km journey home without issues (lights were off). When I came home I tried blinkers again, no issues. New battery had 12,4 V (engine off), 13,1V at 1500 rpm The old battery had 11.6V and is now charging. My questions are: Why? What happened? Is there an issue with Reg/Rec? (it is charging now so how can that be?) Could it be water from the washing? Thanks! Link to comment Share on other sites More sharing options...

SportTouringCZ Posted March 23, 2019 Author Share Posted March 23, 2019 Thank you, I completely forgot about "the Drill" article. Did the drill, it pointed towards Rec/Reg. I have consulted this with my mechanic who seconded the thought. I have just installed the new one and will measure the current after the VFR cools down again. However I think the problem is solved.

SportTouringCZ Posted March 24, 2019 Author Share Posted March 24, 2019 That is definitely going to happen, VFRness is in, meter is next. FYI: Tourmax are Japanese made spares. I have used their steering head bearings and fork seal kits and I like them. Hopefully the quality of Rec/Reg will match. Thanks for help. Link to comment Share on other sites More sharing options...
