Features To Compare When Choosing A Portable Generator
When shopping around and trying to find a portable generator, you will want to make
certain that you check a few things out and compare different types before buying anything.
Here are some of the most important features that you should take note of:
1. The Electric start of the portable generator. This is a significant component that you should
keep in mind and take care to get this right if you want less difficult function.The electric start
is what allows a person to turn the generator on apart from using the starter rope.
Some people find this more convenient than the manual option.
2. Another one to consider is Low Oil Shutdown. Many experts highly recommend this feature,
since it would stop the engine once the level of oil decreases beneath a secure level.
3. The Idle Control feature. This function spontaneously inhibits and suppresses the engine if
there isn't any power being supplied from the alternator. Idle control can enable you to preserve
more fuel than you normally would, allows for a quieter generator, and decreases ...

Fixing Your Portable Generator
So, you've brought your generator out of storage, filled the tank, pulled the cord, and nothing. Hopefully, you are finding this out BEFORE the power outage or camping trip. This article will help you fix some common problems you may encounter. Before attempting any repair, remove the spark plug to prevent accidental starting while you are working on the unit.If the generator will not start or won't stay started, check the muffler exhaust for an foreign debris. Once that is clean, check the gas and oil to make sure you have appropriate levels of both. Finally, make sure the spark plug has a good connection.
If the alternator fails to excite, it may be running at too low of a speed. Adjust the rpm. This can also result from a faulty capacitor or windings, which must be replaced and tightened.
If the voltage is running high with no load on the generator, you may need to adjust the rpms to a lower speed or replace the capacitor. Conversely, if the voltage is running low under no load, you may need to adjust the rpms to a higher speed or replace the capacitor with one with a higher rating. In addition, for low voltage, you should check your winding resistance and replace your rotary diodes, if needed.
If your voltage is ok with no load, but drops when you add a small load, you may need to increase your rpms or remove some of the load. You could also need to replace your rotary diodes.
If the voltage drops when you add a high load, you probably need to adjust the rpms or remove some of the load.
Finally, if the voltage fluctuates, it may be the result of loose or dirty connections. You may also need to regulate the rpms to solve this problem.
