No it doesnot causes any problem. If you have noted on your laptop's charger, the input voltage is AC while the output is DC. so whatever goes in, it always give out the clean direct current suitable for laptop. My friend Chaudhry siraj always uses laptop on generator and have no issue till now. :-)
Some possible clues: * Alternator/Generator not putting out enough voltage to properly charge system * Voltage regulator problems * Weak battery, or one that's about to give out totally
Perhaps the greatest concern for laptops is something called overheating. This is when the laptop does not ventilate properly and virtually cooks itself with the heat emitted. Other problems include physical damage to the laptop, system slowdowns, failure to power on and other battery problems.
Depends on what Onan you have. Most RV units don't have alternators like a car. They charge through the control system. Off of the main AC generator section.
A bad alternator/generator would cause a 'no charge' in the system, which would drain the battery while running. Also a shor tin the wiring may cause a false indicator light.
Before you try to charge the system, there are couple things you should know about,what type of system, the capacity, and the oil charge and type if you need to add oil.A under or over charge system can cause problems.
Many laptop users have this question and we will answer it right now: The answer is: YES and NO, it depends on the situation. Having a battery fully charged and the laptop plugged in is not harmful, because as soon as the charge level reaches 100% the battery stops receiving charging energy and this energy is bypassed directly to the power supply system of the laptop.
If the frequency of the oncoming generator is slightly higher than the system frequency, the phase angle between the system and generator voltages will slowly change at a frequency equal to the difference between system and generator frequencies.
A brushless generator, in contrast, typically uses a solid-state rectifier assembly in place of the brushes and rings. This assembly contains no moving parts. This is important, as it makes the system more reliable and less prone to mechanical breakdown, jamming or seizing as a result of obstructions in the casing. Instead, a continuing charge is built up by transferring a portion of the generator's AC charge back into the exciter.
It means that your laptop fails.
Too much load for the generator, the generator began to under speed / overspeed, the governor / part of the generator went into failure, the generator capability was not up to the requirements placed by the system (needing to push out/pull in too many VARs), etc. there are many reasons for a generator to drop a load. Because a load dropped, this does not infer that the generator was the cause either (fault on the system, system instability limits reached, system protection tripped - non-generator related protection).
Reverse power flow into a generator can occur during synchronization if the generator is spinning too slowly, or the voltage phase angle is lagging relative to the power system. If the generator is spinning too slowly, power from the system is used by the generator to increase its' speed. If the phase angle is lagging, an initial spike of power will flow into the generator to force it into sync with the system. Typically generator's will match system frequency very closesly, and force the phase angle to leading slightly between the generator and the system. When synchronized, an extra bump of power will flow out while the generator is torqued into phase with the system. This will avoid tripping any reverse power devices.
Check your stereo wiring. The generator light staying on is a sign of a shorted or grounded wire. sounds like you blew a fuse that is tied into the field wire circuit for the charge system
