SOURCE: the wires going to the voltage regulator keep burning up.

Common problem with poor quality parts, the regulator is the problem, the generator is working other wise you would not have fried the wiring, you answered your own question. someone telling porkies to get more money from unsuspecting client?
The regulator controls the voltage not the generator, the generator only supplys the voltage it cannot overcharge unless the regulator is not working properly, simple!

SOURCE: My Yamaha vmax is charging the battery @ 20 volts.

You should take some measurements on your stator cables at idle. Between each pair of the three same colored cables that runs up on your regulator, you should have 14-15V at idle and 30V at 3000rpm of Alternative Current (A.C.).

Can the use of a higher wattage headlamp bulb damage the regulator?


NO
bulbs have nothing to do with regulators
regulators control the voltage of the alternator and therefore the amperage output of the alternator
what higher wattage bulbs will do
if you have plastic reflectors , they will melt the reflectors
if you run too high a wattage bulbs , you will burn the wiring harness to the lights as the current draw will exceed the wire capacity to handle the amps
if you have current 55/65 head light h4 bulbs then going up to 55/85 will be about as high a wattage you can go before you have to consider relays for each bulb and the reflector quality

BUFFALO TOOLS 2000 WATT GENERATOR 12 VOLT OUTPUT BUT NO AMPS WILL NOT EVEN LIGHT A 12 VOLT TEST LIGHT BUT VOLT METER READS 12 V.D.C. WHAT IS WRONG ? PLEASE HELP.LABEL SAYS FOR 12 VOLT BATTERY CHARGING


have the voltage regulator system checked
in the regulator the voltage controls the amperage allowed and it that unit is not working properly then there will be no current out put
that regulator could be part of the control board for the main ac out put and may have developed a fault in the section for 12 volts on the board
there is a limit on the charge rate for the battery and if it is exceed it may have damaged that circuit or possible blown a fuse in the amperage circuit

What is causing the battery to drain?


Running the car will drain the battery it if it's not charging ! An if your charging light is on it isn't charging ! Did you check power an grounds on the alternator ? There is a single heavier wire on the back of the alternator, this should have battery voltage ! You may want to take this to a ASE certified repair shop !
Functionality
With the ignition switch in the RUN position, voltage is applied through the warning indicator I circuit 904 (LG/RD) to the voltage regulator. This turns the regulator on, allowing current to flow from battery sense A circuit 35 (OG/LB) to the generator field coil. When the engine is started, the generator begins to generate alternating current (AC) which is internally converted to direct current (DC). This current is then supplied to the vehicle's electrical system through the output (B+) terminal of the generator.
Once the generator begins generating current, a voltage signal is taken from the generator stator and fed back to the regulator S circuit 4 (WH/BK). This voltage feedback signal (typically half the battery voltage) is used to turn off the warning indicator.
With the system functioning normally, the generator output current is determined by the voltage of the A circuit 35 (OG/LB). The A circuit 35 (OG/LB) voltage is compared to a set voltage internal to the regulator, and the regulator controls the generator field current to maintain the correct generator output.
The set voltage will vary with temperature and is typically higher in cold temperatures and lower in warm temperatures. This allows for better battery recharge in the winter and reduces the chance of overcharging in the summer.
Battery Positive Output (B+) Circuit 38 (BK/OG)
The generator output is supplied through the battery positive output (B+) terminal on the back of the generator to the battery and electrical system.
I Circuit 904 (LG/RD)
The I (ignition) circuit 904 (LG/RD) is used to turn on the voltage regulator. This circuit is powered up with the ignition switch in the RUN position. This circuit is also used to turn the charging system warning indicator on if there is a fault in the charging system operation.
A Circuit 35 (OG/LB)
The A (battery sense) circuit 35 (OG/LB) is used to sense battery voltage. This voltage is used by the regulator to determine generator output. This circuit is used to supply current to the generator field (rotor). The amount of current supplied to the rotor will determine generator output.
S Circuit 4 (WH/BK)
The S (stator) circuit 4 (WH/BK) is used to feed back a voltage signal from the generator to the regulator. This voltage is used by the regulator to turn off the charging system warning indicator. The S circuit is fed back externally on external mounted regulator generators.

How i fix the headlight bulb always busted due to over current of alternator is that a relay problem? when i change with new bulb even if the engine is in idle and suddenly it will turn fast thats the


it is not the relay but the regulator that is allowing a surge of excess volts. this excess voltage increases the current and that is what is blowing the bulbs. Have the alternator bench tested along with the regulator.

Your regulator may have went bad. The regulator converts the ac charge produced from the alternator into the DC volts required to charge the battery. When they fail they can put out 5 times what the battery needs. Depending on your bike the regulator may be separate from the alternator. You should pick up a cheap volt meter. Once you get the bike running, use the volt meter to see what the bike is charging at. If you find the charge is above 14.8 V or that the voltage fluctuates to the extreme, ex. 14.2v, 8.2v, 12.7v all within a few seconds. then the regulator is probable. Another problem I have found is that the ground wire for wiring harness does not get hooked back up. This is a smaller ground wire that may plug into the main ground cable or sometimes is a separate lead connected to the battery. This will fry an entire system.

1982 gs1100gl tail light bulb burns out as soon as rpm increase


You are probably dealing with bad grounds or ground wires. If loosening and tightening/ unplugging and replugging in the wire connections does not fix it , you are probably dealing with a bad regulator/rectifier.

Check or have checked your alternator voltage. If you get more than 14.6 volts wile engine is running, the electronic voltage regulator maybe failed or damaged. If there are permanently more than 14.6 volts in the system, it cause more damages as only some bulbs, but the bulbs burning first.

Do not field out the field wire.
Is the alternator ight coming on?
If you rev engine, does charging system start working?
There is a resister wire that provides voltage to the field circuit. If the resister is bad, you will only get voltage to the field through the dash alt. light bulb when you push enough voltage through it.

I don''t have 1993, but here is 96:

Generator with Integral Rear Mount Regulator, Internal Fan Type With the key in the RUN position, voltage is applied through the charge indicator lamp I circuit to the voltage regulator. This turns the voltage regulator on, allowing current to flow from the battery sense A circuit to the generator field coil. When the engine (6007) is started, the generator (GEN) (10346) begins to generate alternating (AC) current which is converted to direct (DC) current by the rectifier internal to the generator. This current is then supplied to the vehicle's electrical system through the battery positive voltage (B+) terminal located on the rear of the generator. Once the generator begins generating current, a voltage signal is taken from the stator and fed back to the voltage regulator S circuit, turning off the charge indicator/lamp. With the system functioning normally, the generator output current is determined by the voltage at the A circuit. This voltage is compared to a set voltage internal to the voltage regulator, and the voltage regulator controls the generator field current to maintain proper generator output. The set voltage will vary with temperature and is typically higher in the winter than in the summer, allowing for better battery recharge. With the system functioning normally, the generator output current is determined by the voltage of the A circuit (battery sense voltage). The A circuit voltage is compared to a set voltage internal to the voltage regulator, which controls the generator field current to maintain proper output. The set voltage will vary with temperature and is typically higher in the winter than in the summer, allowing for better battery recharge in the winter and reducing the chance of overcharging the battery in the summer. A fuse link is included in the charging system wiring on all models. The fuse link is used to prevent damage to the wiring harness and generator if the wiring harness should become grounded, or if a booster battery with the wrong polarity is connected to the charging system.

Low voltage only or can timer be used for 110 v


1 hp= 750 watts
125 vac = 125 volts alternating current, wall outlets
5 amp= 5amps

125vac x 5amps= 625 watts

a timer is a switch with a clock on it. just like a switch in a lamp cord.
