Hi, Sj88kc the following applies to carbureted also fuel injected models and the usual suspects are:
1. Severely discharged or damaged battery, 9 volts or lower.
2. Failed alternator/generator and or voltage regulator.
3. Loose or corroded battery terminals and or cables especially the "NEGATIVE" cable, look for loose, corroded, or broken connectors inside the cable harness at "BOTH" ends.
4. Failed main circuit breaker or ignition switch, check for loose connections and continuity.
5. Failed system and or ignition relay, check for continuity.
6. Failed ignition coil, ignition/electronic module.
7. Failed CKP, CPS, CMP, MAP, TPS, or BAS sensor, corroded, loose or broken wire connector pins/sockets.
8. Throttle cables and or idle speed improperly adjusted hot idle speed should be 950 RPM to 1000 RPM.
9. Air/fuel mixture screw improperly adjusted.
10. Water or dirt in the fuel system, carburetor or filter.
11. Restricted, blocked or kinked fuel line.
12. Fuel tank empty.
13. Gas cap is not venting properly or fuel tank venting system blocked.
14. A failed fuel pump, pressure regulator and or fuel injectors.
15. Vacuum line from intake manifold to petcock broken, cracked, or not attached, carburetor vent line plugged.
16. Needle and seat stuck closed in the float bowl.

Use volt meter on battery and see if regulator/rectifier is fully charging battery. Should read over 13 volts at about 2500 rpms. if not , bad re/rec. If it does, then it's probably bad battery, take to local shop to test. Should be a free test at places like Autozone, Pep Boys etc.

Hi karinanina_k ,

You should find the fuse box under the hood , most probably beneath the sterring in the right hand corner.

I would recommend you to replace the blackened fuses and replace them with the appropriate fuses that are required as per their voltage.

There could be another problem which is bad earthing or grounding box, or the earthing box is not properly fit in it's place , you should check the earthing box in the bonnet and then check if there are any wires that have got carbon on it and then clean them with polish paper and connect them again.

hope this helps ...:)

Sportsman 800 I have no charging and no RPM on the meter


Check all connections to see if they're loose and check the wires that go to the voltage regulator to see if it's not unplugged a bit, had problems with mine and the wire in front of the bike by the rad was slightly disconnected,wouldn't of notice if i didn't check every wire plug-in, fixed my problem, i also had the battery blinking on the the dash. hope your voltage regulator is not shot.check your battery with a meter (12.4-12.5) is good.

1996 Kawasaki VN 1500 Vulcan Classic stator keeps melting


Hi, Mrmiller6514 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 airflow 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.

Hi and welcome to FixYa,

The heating up would be normal as relatively, high current is passing through these wires/terminals not only to charge the battery but to power the electrics of the bike. If the regulator is working correctly, it would soon dwindle down since presumably the battery has been charged. Almost always, the connector used is not plastic but phenolic or epoxy based due to this very reason.  Another possible reason for excessive heat is that the terminals are not tighly fitted to its counterpart connector. A loose connector would result in a slight voltage drop but high current accross the connection.

Good luck and thank you for asking FixYa.

Melting rectifier on ducati 900 ss


Hi and welcome to FixYa,

Offhand, it is a known/common failure of the regulator. This is especially so for those models with 2 phase alternators (2 yellow wires). The charging current is shared by only 4 diodes (rectifier). I have replaced in my 907 with 3 phase (3 yellow wires) effectively increasing the diodes to 6 thereby distributing the current and lessen the heat build-up. The charging also improved as noted by brighter headlights. In the 907, the yellow wires passes on the left side of the bike from the regulator to the engine. There are also connectors along the way that gets corroded.

Good luck and Thank you for using FixYa. Happy Holidays.
