I have Tiger TG-2700 gazoline generator was working properly but stopped giving power ( nearly 6 Volt not 220 Volt as in real). I released 4 diodes connected on armature to test them but i think the problem is the 25 micro farad / 300VAC Capacitor. I just need to how that 4 Diodes are connected? I forgot the proper direction of one diode.

First, I'm not a Coleman Tech.
* First check the generator for a wire(s) output description. This will confirm what each wire is producing and where it should be connected to.
* The specs will also give you an idea of what to expect from a particular generator. (Don't expect 220Volts from a 120 Volt small generator.. Hence the 120 VAC generator will only have 3 wires instead of 4 wires for a 220-240 Volt generator. DC/AC generator will have 5-6 wires.)
* In general, on/off switch on the electrical part of the generator (the actual electric source) is on once the engine is up and running. Electricity is being produced at this time. The on/off switch is usually the main electrical breaker that is rated for the full output of the generator. This is very similar to your house breakers except for a modification of the hook up terminals used to wire in this safety component. Like most breakers there is an input(s) then output(s). Usually the input lines will be black, white, with an additional green wire that is also connected to the frame of the generator. These three wires will hook up to one side of the breaker or the "Line In" side or "L1,L2" The other side of the breaker should have been hooked up directly to the 1 or 2 duplex (120VAC) outlet panel.
* on larger generators that produce 120/240 VAC 1PH (two 120 volt AC outputs with alternative 220-240 volt AC) There will be an additional wire that may be the same or different color IE; 2 Blacks, Reds, or Blues. This is hooked up in similar fashion to the breaker except there will be an additional section to the breaker or even two single breakers stuck together with a bar across both switches. (again similar to a 220 VAC breaker used in a house panel.) The extra wire will go to the 2nd section of the breaker. The other side or "output" of the breaker will be wired directly to a set of Duplex outlets (a pair or 4 outlets) AND a 4 pronged 120/240 1PH outlet "Twist Lock" style. (though you may find specialized outlets for single purpose generators.)
* Larger generators may also have a DC (12 or 24 VDC) wire which is of a different color from the AC wires. Expect it to be Black, Red, or White. (Black or white is probably the negative with the Red as positive.) If you do have DC wires then it's more than likely the AC wires are of different colors to avoid getting the DC mixed up with the AC side.
* Final; check your warranty. Have your vendor or MFR perform a service and annual maintenance check which is a good idea as they can change out your air and fuel filters. Check and clean the spark plug. Make sure everything is working properly. The peace of mind is worth it.

follow this steps and test and fix it. God bless you

1)Diode

The high voltage diode converts the A/C power output of the transformer to D/C, doubling the voltage to nearly 5,000 volts. This high voltage powers the magnetron which emits the energy that cooks the food. If the diode burns out, a lower A/C voltage reaches the magnetron, which is not sufficient to power the magnetron. When the diode fails it is often visibly burned out. If it appears to be good, it can be tested with a volt-Ohm meter capable of testing diodes. High voltage diodes frequently fail and are one of the most common points of failure in a microwave oven. A regular meter with a diode checker will not work to check these diodes. You have to use a meter with a 9 volt battery or put a 9 volt battery in series with the diode to check it.

Door Switch

If the microwave does not heat, one of the door switches might be defective. Microwave ovens normally have three door switches, if any of them fail the microwave does not turn on and does not heat. Check the switches for continuity with an Ohm meter.

Magnetron

If the microwave oven doesn't heat the magnetron tube might have burned out. The magnetron uses high voltage, high current DC power to generate the microwave frequency that cooks the food. If the microwave oven is turned on when it is empty this can cause the magnetron to burn out. Once it is burned out it has to be replaced, it's not repairable.

High Voltage Capacitor

If the microwave doesn't heat the high voltage capacitor might be defective. The high voltage capacitor works with the high voltage diode to convert the output of the transformer to DC voltage and to double the output voltage. If the capacitor is burned out the entire high voltage circuit stops working properly. The high voltage capacitor can be checked with a special VOM meter which has a capacitance testing capability. Be aware that the high voltage capacitor can retain a charge of more than 3,000 volts and can injure or kill a person if not handled properly. Only trained technicians should perform this type of testin

High Voltage Transformer

If the microwave does not heat, the high voltage transformer might be burned out. Microwave ovens produce a very high voltage in order to power the magnetron antenna, which emits the energy that cooks the food. When a high voltage transformer fails it will usually arch and have a burning smell

Thermal Fuse

If the microwave doesn't heat the thermal fuse may have blown. It can be tested for continuity. Watch our fuse testing video for more information.

Thermoprotector

If the microwave doesn't heat the thermoprotector may have tripped. This is a safety device to prevent the microwave from overheating. It can be tested for continuity to see if it's blown.

If this is a battery powered CD player,
we are talking mA not amps.....6 x 1.5volt batteries give you 9 volts
I would recommend something like this:-
http://www.ebay.co.uk/itm/New-AC-DC-Universal-Travel-Adapter-Input-110-220-Volt-7-Output-500mA-/251316939793?_trksid=p2054897.l4275 This will have more than enough power for the CD Player.

Your refrigerator has a freon that we call R-717 which is amonia. You have to heat the amonia to have refrigeration. using the 12 volt side will cause power drain on batteries. If you had to close the gas valve most of the way down this is telling me that he gas pressure regulator went bad. The 220 volt heater is still working that is why this is working. change the regulator and you should go back to gas for operation. If the helps give me a rating please. thank you.

No. They are fine. The voltage is 220. But the amperage is nearly nothing because its just for signaling the generator and switch when the powers out. I install, repair, and service generac products for a living.

High no-load voltage Capacitor with high capacity
Check and replace. Low no-load voltage Speed to low Check and adjust rpm Faulty rotary diodes Check and replace Breakdown in windings Check winding resistance Capacitor with low capacity Check and replace. Proper no-load but low loaded voltage Capacitor with low capacity Check and replace. if wires are connected start with the Diodes first electronics parts stores will have these in stock as well as cheeper. hope this helps

Typical diodes are 10 amp for these. The stator and rotor both have VERY low resistance readings. The reading typically will be below that which will register MEANINGFULLY on the digital meters.

My generator had 10 amp diodes with surge protectors across them. One of the protectors shorted and generator output was zero. Mine is a 6KW diesel silent unit.

Replaced the diodes with 70 amp ones with surge protectors that have 20 times the energy absorbtion as the originals. Unfortunately this required some lathe work to make holders for the diodes and the surge protectors to ride on the rotor.

Used the light bulb trick to remagnitize it once diodes were replaced.

most generators have a 220 volt plug on them from the factory, if it is a small one it might not have the capabilities of 220. If it has the 220 plug then you will just need to wire the proper 220 male end onto whatever you are trying to run.

Two suggestions. One: check for voltage from the secondary coil wires (if it has one). Two: unless stated do not do this, I have always flashed the excitor circuit through the 120vac receptical. Give these a shoot and I hope it works for you.

you need to use a volt meter and test which lead from the 4 wire output of the generator a 220 v is coming out.

the round center prong of the ac is its ground and should not be connected to any live power. it could be left unused.
