Wire connector between stator & voltage reg/rectifier burnt

My stator on 01 V-Star 650 Classic went out 6 months ago. I replaced it (& pick up coil while I was there) & started charging fine. I removed the tank this weekend to do tune up & found stator wire connector between stator & voltage reg/rectifier burnt. I repaired/replaced connector. Wires get very hot in less than 5 min. of running. Book says stator wires should read .5 ohms. They read .3. What is burning the wires/stator? Can you test the voltage regulator/rectifier? Book says if voltage is 14V @ 5000 rmp, voltage regulator/rectifer ok. I don't have tach but I only achieve around 13.5 when reved up. Any ideas?

    replaced stator, voltage reg (twice due to first replacement being bad). unit is charging OK, not draining batt. replaced starter and solenoid and several relays, switches, etc. seems like it's not getting enough juice to starter. turns over once then struggles to turn over a 2nd time. can start with 12v on the jump but won't start itself.

    BATTERY is BAD. If you charged up the battery completely for hours, Then put a DC voltmeter on the battery terminals & hit the starter button. The voltage should not drop below 10 volts. If so, The battery is bad & needs a good replacement. There are many defective stators, regulators, & relays being sold on Amazon. JUNK !

Your voltage/reg. can be tested in a couple different ways check ground res. check res. then revs. bias on diodes you have ac in dc out it sounds like you may have a diode gone bad allowing ac curent to flow causing the wires to get hot

Coils 2 and 3 are not firing?

looks like a lot of problems
start at battery a fuse if any to ignition pick up
to ignition module if fitted to coils

stator and regulator are just a plug in
when possible check the battery is now charging at correct volts /amps

Started up for first time this year at first it was running fine now it is back fireing and dogs off on take off I put new gas in it.

Hi, Anonymous if your bike has been sitting idle for months or years and you did not do any pre-storage maintenance I feel your pain it will probably have a dead battery and not want to start or if it starts it will idle and run poorly, here are the following steps necessary to complete in order to get your bike back to an acceptable running condition.
1. If your battery was 2-3 years old when you last had the bike running you should replace it.
2. If you believe your battery might still be serviceable remove it from the bike and put it on a 1 or 2 amp trickle charger for 24 hours. If it is the old lead acid type with visible cells and acid levels fill each cell to the top line with distilled water and replace the caps, run the vent tube into a plastic or styrofoam cup, any cells that are cloudy/milky replace the battery.
3. After charging remove the leads and let the battery sit for a couple of hours then check the battery voltage with a volt meter, you should have 12.5 volts or better, any readings in the 11 volt range you need to do a proper load test on the battery and replace as necessary, any readings in the 10 volt range you have a dead cell and replace the battery.
4. Drain and flush fuel tank, google " how to clean a motorcycle gas tank" find a couple forums to view the different options available.
5. Remove your air cleaner and clean and re-oil per Mfg. specifications.
6. Remove the carburetor, disassemble and decontaminate with a carb dip or if you have EFI remove injectors and clean with carb spray and compressed air
7. Remove fuel valve and filter disassemble and clean as necessary, remove fuel lines and replace with new ones.
8. Replace spark plug with a new one and check for spark.

I have a 04 V star 650 and it is not firing, need answers!

You will need an ohm meter. First check to see if your kill switch is working, by unplugging the switch and testing continuity in run and off positions,if that is ok, then you need to check resistance in the pickup coil.On the lower left side of the motor you will need to trace wires from the stator up to the cdi. Disconnect the two pin connector. On the stator side of the connector measure the resistance between the two wires. Ohm reading should be 188-222 ohms at 68 degrees. if it out of spec you will need to replace the pickup coil.

Charging problem

As the battery & regulator/rectifier have been replaced, the only other things to check are :-
Continuity from reg/rect red wire to battery & to earth, then check for continuity between each of the 3 yellow wires, all should be the same resistance - if not the stator coils in the alternator are faulty

Ride safe
Please mark this as very helpful (if it has been!!)

Two years ago my Voltage Regulator went bad and over-charged my new battery to the point that it swelled up. The Yamaha dealership replaced both the battery and Voltage Regulator. Two years, almost to the...

If you're going through regulators that often I would suggest going after the stator. Make sure it's not grounding out on the chassis. Find the 3 yellow or white wires that are connected to the regulator. using a meter in OHMS ( looks like the horseshoe ) with the bike off check wire one (red ) to wire 2 ( black ) then wire one ( red ) to 3 (black ), then 2 (red ) to 1 ( black ) and 2 ( red ) to 3 ( black ) , then pick one ( red ) and black to the chassis, motor, ground. somewhere metal on the bike. The first series of tests you should get some sort of numbers, ( which should be somewhat close in numbers ) When you go to ground, Chassis you should get no numbers, OFL, OL, or the horseshoe sign if you get numbers there, the stator is bad and your transmitting ac voltage to the chassis.

2004 Yamaha V-star 650, wont start.

change the coil you may not think it got hot but sometimes a coil can overheat on the inside just enough to break the copper winding. when riding hard slow down for a couple of miles to give everything time to get back to normal temps before shutting it off
