I've used the search function with several variables with no concrete success and my Haynes manual only covers the single-phase regulator rectifiers. Here's what I got: -Charge the battery wait 30 minutes after disconnecting and it shows good volts. -Disconnect the ground (-) terminal and check the draw with all systems off 0.6mA. That's a bit higher than I'd like but not horrible. Disconnecting the ECU fuse it drops to nil. -Reconnect and run the engine at idle the volts across the battery show right about 12. -Increase RPM to 3000 and the volts steady a bit but still remain at 12. Everyone seems to think that stators rarely fail on these machines, but I'd like to be certain before I drop $80 or more on the regulator/rectifier. Anybody out there got a good idea?,Battery voltage at the battery should stabilize at aroun 14V, not 12V. The battery should be at about 12.5 when left overnight. My ST2 will hit 14V at 2k RPM with no lights, 3lk with low beams, 4k lo+hi.,,,

1993 Vmax. Why is regulator/rectifier overheating?

You are not going to like this answer but here goes. All Motorcycles, mopeds, scooters, quads, etc, that have have a stator to regulator/rectifier to battery generating system all have the same design flaw. They all have lousey electrical connectors. Heres what happens: the stator produces 204-220 volt ac current. The same thing that will run an electric dryer in your home. It's a lot of power. That power gets changed to dc current by the recifier and converted into about 15 volts by the regulator in the same unit. That's a lot of heat energy. If at any time the electrical connections become compromised by vibration, oxidation, dampness, salt, or will see the wires fry. It's an over load...not a short. Power sports shops are well aware of this and are happy to charge you list price to replace the entire system for several hundred dollars. Usually between $800-$1000. You can get after market sets of the component parts and do it yourself and that's the only way I know of to avoid the cost & it still ain't cheap. Many moto-X riders replace the connectors with automotive plugs that seal out water, dust, etc with a recessed plug with a silicon gasket and seal it with dielectric grease to prevent oxidation. Like the plugs on a car's O2 sensors. Hope this has been helpful, Sorry to be the bearer of bad news.

The bike probably has a faulty charging system. Need to check regulator/rectifier for proper operation as well as the stator's output voltage on all 3 phases. They usually blow out the regulator though.

2003 Ultra Classic fuel injected model. Generally runs well, but at times (seems when it's been run hard for an hour at least) I see the volts go way up around 16 or 17; it normally reads 14.5 volts Soon...

Your Voltage should never get that high. Anything over 15volts is bad news. Try Testing your Regulator. First do a Bleed Test.
Be sure regulator is connected to battery. Unplug the stator connector.
Use a trouble light and clip it to a good ground and the other to the regulator pins, one at a
time. If light comes on regulator is bad.

2002 honda 1100cc shadow sabre What is the purpuse of the rectifier? Bike runs great for thirty miles on charged battery then quits. While running disc pos. lea to battery an bike quits. should it still...

On motorcycles the regulator/rectifier are usually one unit. The voltage regulator takes the juice coming from the alternator and converts it , usually from a higher voltage, to 12 volts. The rectifier takes any extra power left over from the conversion and dissipates it in the form of heat. Honda motorcycles draw power from the battery to run everything on the motorcycle. When you disconnect the battery it is like turning off the key. If your battery is not charging check the alternator first. Find the plug coming out of the engine with three yellow wires. You should have continuity between any combination of these three wires. You should have no continuity between any of these three wires and ground. If If you get no continuity between any of the yellow wires or you get continuity between a yellow wire and ground , you need a new alternator. If the alternator checks good and the battery passes a load test, then you probably need a new regulator/rectifier.

How do iknow if my voltage regulator is bad on my 1993 yamaha fzr 600

hi normaly replacing it with another 1 is sometimes the only way to tell, even when tested some electrical items *** up as testing ok, and when you replace them the fault is cured, what is the fault you are getting? is your machine fitted with a seperate voltage regulator, most machines have a regulator rectifier combined, the rectifier converts alternating current ac to direct current dc, where as the regulator controls the amount of voltage, regulator problems overcharging, rectifier problems not charging, and discharging as the rectifier only alows current to travel in 1 direction, when it fails the battery voltage can then travel past it causing a discharging state

Cx500 not charging

First have your battery load tested at a dealer. If the battery is good find the plug that comes out of the back of the motor that has three yellow wires coming out if it. You should have continuity when you check any combination of these three yellow wires. You should have no continuity between any of these wires and ground. No continuity between the yellows( even if just one pair) or continuity between yellow to ground means you need a new stator. If the stator is good you probably need a regulator/ rectifier.

Battery went flat even after riding for hours. showing 12.7 volts. When ran engine with revs it measured 12 .22. Think it must be rectifier. What should be output with engine running on 2001 softail duce

Proper battery charging will show ~13.5 to 14.5 volts at the battery terminals. Check for continuity through the alternator windings, check each diode in the rectifier stack and look for a voltage regulator which may be defective.

Charging problems on my 1983 Suzuki GR650 tempter

The only easy way is for you to buy the service manual - it is pretty hard to tell you how to service your regulator if you don't know what it is...
And it is - or at least something in the charging circuit.
Early Suzukis had consistent charging problems, resulting in run-down batteries, short battery life, hard starting and frequent stator and regulator/rectifier replacement. Some of the problem is due to poor quantity or corroded electrical connectors, some to a poor ground to the regulator/rectifier and some just poor quality components or design. Keeping the connectors on the three stator wires clean and by running a heavy ground wire directly from the negative terminal of the battery to the regulator/rectifier mounting bolt will help.
You can download the GR650 manual here - just look for the tiny "Save file to your PC: click here" at the bottom right of the page.

1992 vfr 400 not starting

I have referred to this website on more than one occasion and found it useful. This guy had to replace his regulator and tells you how to check yours and the options available when replacing it. They have a tendency to overheat as they don'y have cooling fins. You are best to replace it with an aftermarket one with fins so it doesn't go again.
