No, it is not safe but is done. As a temporary measure to get the vehicle started. Remember that the starter winding are only rated at its operating voltage and not twice the voltage. Don't let it crank very long as the starter will get very hot and could probably burn the windings out.
NO! That is a very big difference in voltage. You can easily burn it out.
The 24v battery is used to provide the initial field current. This couples to the stator windings, and as the generator spins induces a voltage on the stator windings, which causes back EMF onto the field windings (when load is present), which slows the generator's spin until the governor kicks in to bring it back up to speed. The important thing to note is the output power of the generator is not a factor of the 24v field voltage, it is directly dependent upon the fuel being used to get the generator spinning. The 24 volts just "jump starts" the field voltage. Think of it as synonymous with the 12 volt battery that starts your car.
There is no way to answer without knowing the wattage rating of the 9 volt generator. A generator's wattage rating depends on the size of the wire in it, the wattage of the rectifiers if it is a DC generator, and the horse power of the engine or motor that is available to turn the generator.
The generator should be about ¾ hp.
This is not advised! The 9-volt charger might have a current limiter so that nothing burns up, but it any case if left on it will destroy the 6 volt battery by overcharging. A 6-volt charger is not expensive.
The value of internal resistance of 1.5 volt battery is 0.5 ohms.
No
As long as the battery in the lawnmower is a 12 Volt battery you will be fine.
Yes, but you may damage some of the electronics.
I would not I would buy a 12 volt charger and plug it in for a day
If you jump a car or other vehicle with a 6 volt electrical system using a 12 volt battery, you can blow out the 6 volt battery. When they are connected, it usually only takes a fraction of a second to start the six volt system. There should be a person ready to start the 6 volt system immediately if not sooner so the 12 volt system can be disconnected immediately before the battery overheats and burns out.
a trickle charger will not jump start anything,however if it is left connected long enuff, and the battery will take a charge, the mower should start. to jumpstart, a mower, you can use a car the same as you would jump start another car. just make sure battery in mower is 12 volt same as car
Yes, if the two 6 volt batteries were connected together in series.
Two 6 volt batteries in series, yes. In parallel, no.
Yes, you could but you would damage any electronics on the truck that were on when you jump start the vehicle. I would advise against it.
Remove the fan belt.Connect a jumper from generator DF to the frame (or generator D- pole, if it exists).Pick up battery plus with a jumper cable and touch the generator D+ pole - the generator should start spinning. Do this only for a few seconds to avoid overheating. The generator is polarized now.
If you turn the key and the lights in the instrument panel dim but the engine doesn't start... or if the battery volt meter is in the red or low. This indicates that the battery is or may be dead and you need a jump. The only thing a jump can help you with is a dead battery. You may need a new battery if your engine has taken longer to start in the previous days/weeks. The battery may be fine and just need to be jumped if all you did was sayy... leave the lights on and run the battery down.
Start the generator and check the voltage output at the receptacles on the generator with an AC volt meter.
