And what wouldn't work if one or the other went bad? Right now when I turn the key from OFF to ACCESSORIES the headlight will come on and the starter will run when pressed (the bike won't start though) but when I switch the key to IGNITION everything goes dead. The switch is new so it's probably not that. I'm not an electrical system expert but this guy's page has helped me many times. He discusses rectifiers about a third of the way down... but you'll probably learn a lot by reading the whole page and eventually the whole site. He has really good info about most aspects of MC repair. http://www.dansmc.com/electricaltesting.htm,,

Explain the difference between static electricity and current electricity


Static electricity...

Generally considered a nuisance... can cause serious damage to electronic equipment... (it is STORED power)

Thunder & lightening are STATIC electricity...

Wiki definition included (below)

For commercially available ELECTRICITY...
(usa) "currents" ... All electricity functions because of a DIFFERENCE in potential. When you start adding wires then you are harnessing that potential DIFFERENCE into usable energy.

Direct current & Alternating current... Generally referred to as "AC" & "DC"

Most all of the power grid you are looking at on power poles around your community... have "AC" flowing on the power wires
good for powering residential housing and commercial power applications

Immediately below those wires ... The phone wires
have to run about 10 feet below the "AC" wires...
Phone systems run on "DC" because it is quiet
(communications systems).

Alternating CURRENT can be rectified into Direct...
and Direct CURRENT can be inverted into Alternating.

Generators,
solar panels & BATTERIES output DC
Which can be accumulated and stored.

Alternators
output AC... and because AC is less susceptible to magnetic interference... it can travel great distances with very little loss.

Very interesting topic for further research ... and the principals of both... as argued by no less than Nicola Tesla & Thomas Edison.

Hope this helps

What is the rectifier for the scag zero turn riding mower


You did not post what model this is on. However this is most likely the voltage regulator on the engine. The Scag brand has numerous issues with this item and electrical problems in general. I would contact SCAG about it.

    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 dirt...you 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.

    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

    What is the function of rectifier? And how will I know if it is broken already


    The rectifier convers AC current to DC current by blocking the wrong polarity of charge from the altenator allowing the correct polarity charge to enter the battery and run the electrical stuff on your bike. If the rectifier or Diode Pack fails, you will not be able to charge your battery and if it is short circuit will flatten the battery very quickly. There should be some form of regulator after the rectifier that stops the battery from being over charged.
    Hope this explains it for you.

    The battery will not stay charged and the regulator rectifier get hot after running the bike for a short period of time. bike runs but not well when you disconnect the negative battery cable


    sounds like the regulator/rectifier has failed. you need to check that you are getting 13.5 14.8 volts at the battery when bike is running, higher means failed unit and under means same. you need a diode tester to measure reg/rectifier and will also need to check stator output with multi meter on AC, should get 60-100 volts when bike revved with stator wire unplugged from regulator.
    best solution is to take to your local shop and get them to perform these and other tests to confirm as electrical parts are generally not returnable once purchased as very easy to damage if put into a bike with other charging system faults

    Replace regulator/rectifier with a different brand?


    Not always necessary to change the regulator/rectifier. Check all connections to make sure they are clean, use a good contact cleaner and finish off with dielectric grease on your electrical connections.
    When some bikes get a few years on them the connections get dirty. Check to see if there are any burned or discolored wires anywhere around the regulator. The FIX on some bikes is to cut the connector completely out and solder the wires together and either seal them with heat shrink of a good electrical tape. Loose or bad connections get hot. As long as the regulator and rectifier are working there is no need to replace them if the connections are good.

    General electric


    Hi,

    Initially the only easy user action possible is to check/clean the battery contacts/terminals.

    If still a no go, you need to check for any loose or open wiring from the battery compartment to the PCB. That would mean opening the unit and having a look & see inside. You need to be familiar with electronic components and circuitry, DVM and possibly a soldering iron. You need to look/check the power switch, voltage regulator, reverse protection diode, zener diode, fuse/fusiblelink-resistor, open foil/trace and any other components associated with the power supply/regulation.

    If this does not solve the problem, your best bet would then be to seek the assistance of a qualified communications technician.

    Hope this be of help/idea. Pls post back how things worked out or should you need additional information.

    Good luck and kind regards.
