Trying to find out why my stator is burning out this is my second stator I put on 2003 r1


Hi, Rudy and the usual suspects are:
1. Excessive electrical "HEAT" aka "AMPERAGE" melts the varnish
insulation causing the coils to short out.
2. Overheating due to a faulty voltage regulator.
3. Voltage regulator not properly grounded.
4. Loose rotor magnets or stator bolts.
5. Faulty starter relay.
6. Old battery dead cell loose or corroded cables.
7. Faulty wiring in the charging circuit.
8. Excessive wattage in a batteryless system.
9. Aftermarket parts are usually substandard.
10. Headlight not designed for a motorcycle system.
Some bikes have charging systems that get the job done but just barely and will have the most failures, you can upgrade the system with quality parts and a higher output. Relocating the voltage regulator to a spot more conducive to air flow will help immensely. Regular wiring system checks for corrosion chaffed wires, rerouting harnesses that run too close to heat sources ie. cylinders-exhaust etc. is great preventive maintenance to avoid those breakdowns in the middle of nowhere at 2 in the morning.

Battery on 03 r1 dies after being ridden..have replaced stator, battery, and regulator. could it be the wiring harness?


Hi, Anonymous for this situation I would call my local dealer or reputable shop's service/parts department and inquire about any possible quick fix, answers, or parts inquiry. If necessary, transport your bike to the dealer or shop and have a professional technician take it for a test drive, if it is in running condition, and give you a written estimate of repairs and answer any specific questions you may have about your problem.

2001 YZF R1 WONT HOLD CHARGE REPLACED REGULATOR AND STATOR HAS NEW BATTERY WHAT COULD BE MY PROBLEM


Hi, Anonymous in order to check out any main electrical system, you have to start with a fully charged battery 12.5 volts or better, and be able to pass a load test if necessary. "WARNING" never plug or unplug any electrical connector with the engine running !!!
1. Check battery terminals for damage or corrosion, check battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
2. Check the voltage drop at the battery when you hit the starter button, anything below 9 volts you might have a faulty battery.
3. Check voltage at the battery with the bike running at 3,600 RPM should be 14.3 to 14.7 volts. If you are not getting these numbers, you might have a faulty voltage regulator.
4. Make sure voltage regulator is "GROUNDED" and functioning properly, watch the video below on how to test a voltage regulator.
5. Unplug the connector to the alternator and hook your multimeter leads to the alternator (pin/socket selection does not matter) set the multimeter to AC volts, at an idle the multimeter should read 16 to 20 volts AC. at 2,000 RPM 32 to 40 AC volts, 3,000 RPM 48 to 60 AC volts. If you are not getting these numbers, you may have a faulty rotor, follow step 6
6. Set the multimeter to OHM'S, connect one lead to the alternator (any pin/socket) and the other to a ground, the multimeter should read infinity. Connect both leads to the alternator multimeter should read 0.1 to 0.2 OHM'S. If you are not getting these numbers, you have a bad stator.
7. Check all wiring in the charging circuit for worn or chaffed spots and all wiring connectors in the circuit for corroded, broken, or loose pins/sockets, which is the # 1 offender.

Good evening sir, I have yamaha R1 bike. in bike yesterday battery discharge than charge the battery. today bike start and running but after .5 miles bike is stop running, self is not running and battery...


1998 to 2002 have problem with plug to voltage regulator/rectifier which is under seat. connectors in plug overheat and bike stops charging the battery. you will see if connectors have been hot and will need to be replaced if they have.
once replaced check bike charging with multimeter at battery,should make 13.5 - to 14.5 volts just above idle. if not will need to test stator and regulator.

My battery wont charge and I just bought it


Hi and welcome to FixYA,

Two possibilities:
  • rectifier / regulator combo (most likely);
  • corroded, burned, loose connection from the stator to the regulator (likely);
  • faulty stator (least likely).
The stator would be producing relatively high AC voltage while revving the bike. The stator output AC voltage are fed to the rectifier / regulator through 3 white wires. Check calls for testiing for the presence of the AC voltage on any pairing of the white wires before and after the connector before the voltage regulator. Check on the regulator calls for checking the battery voltage when revving the bike (14.5 VDC).

Good luck and thank you for asking FixYa.
