v-star 650 classic voltage regulator - Updated
Got caught on the road yesterday with a dead battery - got the CAA people to bring the bike home - battery was dead flat - charged it overnight abd it's reading 12.6 v / 12.7 v before starting with the lights on for a few minutes to remove float charge.
At starting the voltage did't go below 10.0 v so it's accepting a full charge.
After starting at idle rpm - 12.6 v - with a twist of the wrist to run the throttle about halfway - absolutely no change in the voltage - 12.6 v.
Now without testing the stator I'm assuming a faulty regulator - mostly because if the rectifier failed I'd have a higher than 14v with the throttle opened.
Now to the question - do I have to remove the tank to replace the regulator / rectifier????? Or doe the cable just loop under the tank / engine area????
If I get the regulator connection exposed I should be able to test the stator without any further disassembly????
UPDATE - After a two week wait between the dealer ordering the stator and finding time to get it installed - it turned out to be the stator - Grounded - so have a new updated stator installed - apparently Yamaha superceded the -02 models for a -03 - hopefully this corrects any flaws in the design / installation - total cost $600.00 - priceless - without the stator the V-Star just became a very heavy pedal bike .
Now we have 5 days of sunshine and moderate temperatures so I'll have to catch up on the mileage missed over the break down period.
Now have a new stator - new regulator and new battery - should be good for another 50k
