Unfortunately you are going to need to take her in to have it diagnosed unless you want to just swap the stator and the regulator and call it done. It's hit or miss as to which is culprit.

Microwave runs, but no heat turntable rotates, acts like it is heating but doesn't


Sorry, but probably time to get a new microwave.
The cost of having it fixed is usually more than the cost of getting it replaced unless it's some fancy over the range unit. Sometimes it's a relay that goes, but you'll have to replace the whole control board.
Don't open it up if you don't know what you're doing! As there is a dangerous capacitor and a radioactive element inside.

Our Sharp R-4H88 microwave popped a fuse. Door switches, all OK. High voltage rectifier shows "infinite" R. both directions. H.V. xformer hums when plugged in with door shut. I'm stumped!


If the HV rectifier circuit shows infinite resistance it may be that the transformer winding has failed on one side. Don't forget you must measure this at a point where the diodes are not in the measurement path. It can still hum in this situation.

I have to say this, be exceedingly careful that the magnetron HV capacitor is discharged, not storing a lethal voltage as it can do.

Kitchenaid Superba KEMS307D Microwave buzzes, looks like it works, but doesn't heat. Full normal display, tray rotates, but fan doesn't sound normal.


Most likely causes - shorted high voltage rectifier, or failed high voltage transformer, or shorted high voltage capacitor, or shorted magnetron. If an odor accompanied the failure, high voltage rectifier or transformer most likely. All of these components operate on 4000 v, or more - with enough current to kill you. Make sure the unit is unplugged, and the high voltage capacitor is fully discharged before testing.

2009 suzuki m90 shutting off while riding. recifier?


The regulator /rectifier changes the AC output of the alternator to dc voltage (rectifying) and then limits the dc voltage charging the battery/ powering the electric system. If your battery is discharging so your bike will not stay running and correspondingly not crank over after running, that could be one of the charging systems components gone bad. But if it just stops running could be numerous things. One solution could be problem with side stand safety switch.

Unusual noise and electrical smell


If it's a burning odor, and there's a buzz, or a hum that's louder than normal, failure of the the high voltage transformer or high voltage rectifier would be the most likely cause. A failed rectifier usually looks like it's been hot - may have small bubbles on the surface, or may be discolored. A transformer will emit smoke when 120 volts is applied to the primary. Keep in mind that these things run on 4000 volts, or more. You can easily be electrocuted poking around inside when the unit is running (the capacitor may stay charged with 4000 v for weeks or months even when the unit is off). if you don't have a working knowledge of electronics / electricity, it's best to find someone who does. If the rectifier is bad, make sure you discharge the capacitor with a screwdriver from terminal to terminal, and from each terminal to ground. It isn't pleasant having a 4000 volt jolt of electricity travel through your finger. I know from experience. You finger will light up nicely for a second, though. It's kind of neat, but painful!

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

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.

I asked some clarification questions, but received no answer.

Because I see that your question is still standing, I will try to help you, but I am not sure, because I did not have your answers.

Your inverter I think is not CyberPower, but Thomas & Betts.
Your UPS has internal battery, which depends upon the type of the UPS.

If your battery is 270 V DC (which means 20 x 12 V batteries) 135 V will not be enough to charge them. But if you have 135 V DC (which means 10 x 12 V batteries) you can not give to them 270 V, because you can spoil them.

That's why you should measure the voltage on the batteries, not at the rectifier.
  1. If the batteries have the correct voltage for their number 135 for 10 batteries you can not adjust it to 270, you should adjust 135.
  2. If it is 270 for 20 batt's your rectifier did not get your order.
  3. If it is lower then the number of batteries multiplied by 11 V you may have a bad battery or completely discharged batteries and you need to charge them outside the UPS by other charger (One by one or in series) until their rated voltage is reached.
  4. Some of your internal breakers may not function well.

Battery slowly discharges on my 2002 FXD when engine runns


So you're running off the battery instead of the charging system, check all your wires from the alternator to the regulator/rectifier for open connections or shorts to the frame. You could have a bad rectifier if it's separate from the regulator, you may also have a bad alternator, if you've got a multi-meter check the AC voltage between the ground and each of the three wires coming from the alternator (usually yellow). They should all be about the same, and measure over 16 V, increasing with RPMs. Hope that helps

Battery problems


After you start the bike put the headlight on high beam. Rev the engine and the light should get a bit brighter. If it stays the same or dims the battery is discharging.

If you have a meter, take off the seat and start the bike. Place the meter in DC Voltage mode and place the red probe on the + side of the battery and the - probe on the negative side. It should read 12v to 14v. Start the bike. The voltage should rise to over 13V or at least higher than it read when the bike is not running. If you rev the engine the voltage should also rise a 1/2 volt or so.

If the voltage remains the same or decreases you have a charging problem. Here are the two most likely fixes.

Tighten the battery connections.
The rectifier is not working. It is located on the right rear of the bike under the seat fairing.The rectifier converts the AC voltage coming out of the alternator to DC voltage which is what the battery needs to stay charged.
