One of the most common problems we see in the workshop are electric. Even a lot of good small motor-tech war with these problems. One of the causes of the difficulties of diagnosing electrical problems is that every factory we go to school to teach stress. The tension is almost never the problem. The flow of current. The starter, which is again a good example. Many times people will just buy a new starter that is 12-volt motor with its baseVolt-ohm meter (VOM). Then, a few hours later I am back to the counter parties, because they got what they think is a faulty engine. The new twist neither. So, if you are over 12 volts to the motor, what's the problem. Read on.

The current flow is a bit 'as water flows through a tube. Think of the battery, as the water pump the water in the pipe (wire). Now we are a water wheel and try to think of it as an appetizer. It takes a certainWater, turn the wheel. There are two ways to measure the water in the pipe, pressure (stress) and volume (date). The pipe carries water, the wheel has been designed so that it can provide enough water (by volume) to turn the wheel, if enough pressure to push it through the tube. We put a cork in it with a small integer, at the end of the tube. The pressure (voltage), measure the same at the pump, but the volume (flow) of water that can pass through the cork is notenough to turn the wheel.

Back to our starters. We measure 12 volts to the motor, but through our BY corrosion or loose connections (strength, like our cork above) can not flow enough electricity to power the motor. Often it is the power voltage / current to the device, in this case, our starter, but the return in the battery. A poor soil engine, for example. The electricity needs all the way to the starter from the engine and then back toBattery. Whenever you are trying to solve an electrical problem, the same level for use as the FROM device tested. Do not just hang the meter lead on the battery terminal.

Now you can apply all the above on any electrical device. Whether it's one clutch PTO, lights or starter relay, is the same. 9 out of 10 times the real problem is, a connection that is loose or corroded. Think you have all the current flow and electrical problems that come fixin diameter.
