You won't get dc current, will have to use rectifiers to convert ac to dc and cut out to limit it to 14volts

I have a 6000 watt allpower generator that the 12 volt breaker poped out reset it still no power replaced the avr ran for about 5 seconds then poped the 12 volt breaker again what could it be


The 12v system does not go through the AVR. It most likely is the Battery Charging Rectifier has failed. This controls the voltage from the 12v feed from the alternator and charges the battery.

1) Follow the wiring from the 12v socket/connectors until you come to a Block rectifier. It will be held on by a bolt in the center and have 4 wires connected to it. If you look at the pins you will see one is seated at a different angle to the others. Test the feed to this pin, you should get a result of between 12 Volts DC to 16 Volt DC.
If you are not getting these results then the Block rectifier has blown and will need replacing.

2) If all is testing fine above, then you will need to test the Battery Charging Rectifier as you have an Electric Start and Battery on your unit. This is a metal block located on the back of the engine, next to the starter motor and it has fins running across it. ( to see an example of this part look up your generator on this page Again this should be giving you between 12 Volts DC to 16 Volt DC.

3) Next,check the voltage going into the Battery Charging Rectifier from the alternator. You should get between 12 Volts DC to 16 Volt DC.

For replacement parts please see our web page. You will need the full model number to do this.:

What could be causing my 49cc mini chopper motor from starting?

If its a brand new carb and you have compression and spark most likely the problem is the idle mixture screw is turned in too far or turned out too far I think the proper setting is 1and a half turns out from being lightly seated .if that doesn't work check your spark plug for proper gap or clean it

2003 Chrysler 300M that suddenly drains the battery in a matter of hours. I have replaced the battery 4 times in the past 2 years

You obviously need to have charging system tested, as well as an amp draw test when engine is off. Check, clean and tighten all connections, and don't forget any extra ground straps from engine to body, frame to engine etc.
If all checks out good, and you don't want to pay someone to test for current draw when engine off, you can do it yourself with a 12volt DC test light ( about $5 ) if your willing to spend the time. Make sure if your stereo has anti-theft code, that you have it ready for after to reprogram radio/stereo.
Now remove positive terminal connection on battery. Your vehicle may/should have a connection under hood on passenger side, if battery is located in front of passenger front wheel. The cable going down to battery is the one you need to disconnect carefully so as not to touch against metal on body. If easier to get connection off at battery, do so. What needs to happen is that you need to connect the test light between battery connection, and battery. One end to battery and other to main cable that connects to battery. When there is a current draw, the test light will be illuminated. The brighter the light, the bigger the draw. Now you need to watch test light, or have someone watch it for you and start pulling fuses. If you pull a fuse and light doesn't change, put it back in. If light changes (dims) then you've found a circuit causing a draw. Big change in light, or light goes out, bigger draw, and likely source of problem. Keep in mind that radio/stereo has small draw due to memory storage. What I usually do is pull it and leave it out while testing. You probably have a fuse/relay box under hood on drivers side, so start there. I usually pull door locks, power windows, anti-theft, stereo amp, power trunk etc first, as they can stick and cause a good draw, as well as any fuses for 12 volt power center, such as sockets to plug in cell phones etc. Then go to fuse panel inside if not found. Once light goes out, or gets very dim, you've isolated the circuit causing the problem and can correct from there. . Good Luck
