Lawn Mower Common Electrical Problems

!: Lawn Mower Common Electrical Problems

One of the most common problems we see in the repair shop are electrical. Even many very good small engine tech's struggle with these problems. One of the causes of difficulty diagnosing electrical problems is that every factory school you go to teaches voltage. Voltage is almost never the issue. Current flow is. The starter motor that will not turn is a very good example. Many times folks will buy a new starter based only on the fact that they measure 12 volts at the motor with their Volt Ohm Meter (VOM). Then a few hours later they are back at the parts counter because they got what they think is a New Defective Motor. The new one doesn't turn either. So if they do have 12 volts at the motor what is the problem. Read on.

Current flow is a lot like water flowing thru a pipe. Think of the battery like it is the water pump pushing the water thru the pipe (the wire). Now lets look at a water wheel and try to think of it as a starter motor. It takes a certain amount of water to make the wheel turn. There are two ways to measure the water in the pipe, Pressure (voltage) and Volume (current). The pipe carrying the water to the wheel is sized so that it can deliver enough water (volume) to turn the wheel when there is enough pressure to push it thru the pipe. Let's put a cork with a small whole in it, in the end of the pipe. The pressure (voltage) will measure the same as at the pump but the volume (current) of water that can pass through the cork will not be enough to turn the wheel.

Back to our starter motor. We measure 12 volts at the motor with our VOM but due to corrosion or loose connections (resistance, like our cork above) not enough current can flow to turn the motor. Many times it is not the delivery of the voltage/current to the device, our starter motor in this case, but the return path to the battery. A bad engine ground for example. The current must make it all the way to the starter motor, through the motor and then back to the battery. When ever you are trouble shooting an electrical problem try to use the same ground for your VOM as the device you are testing. Do not just hang the meter lead on the batteries terminal.

Now you can apply all the above to any electrical device. Be it a PTO clutch, headlights or a starter motor relay it is all the same. 9 times out of 10 the real bad part is some connection that is loose or corroded. Think current flow and you will fix every electrical problem you come across.

Applications Of Portable Water Pumps

!: Applications Of Portable Water Pumps

When you hear the word water pump you immediately associate it with the water pump found in the car or the pumps used to move water from the water table to the surface. You even associate it to high-pressure pumps that are often used in several industries like mining and construction. Indeed, all these are applications of water pumps. However, there are also pumps that are designed to be moved from one point to another. These pumps are called portable water pumps. These pumps are small enough to carry and move around and these can come in handy in case of emergencies.

A portable pump can be used for simple applications like draining water from a clogged lavatory or clogged kitchen sink. You can also use this to remove water from the aquarium and prepare it for cleaning. This type of portable pump is called the hand pump or the siphon. This option is much better when it comes to moving water than the idea of using a bucket. There is no denying that moving water from one place to another with a bucket is not only tedious but messy as well. These pumps are small and lightweight. Electricity and batteries are not needed to power these tools up because you need patience and human power.

If there is a need for you to move large amounts of water from one area to another, then a hand pump is insufficient. In place of the hand pump, you can choose to use a battery or electric power portable pumps. You can use this to move melted snow on your pool cover or remove condensation produced by the AC unit. These electric portable pumps are environment friendly and user friendly.

Having portable water pumps around the house can come in very handy in several situations and these can make cleaning a whole lot easier.
