Question about 2002 Yamaha V Star 1100 Custom

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

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


Hi
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

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
