When the current is switched on or off, the electro-magnetic field increases and decreases, rapidly causing, in effect, a radio signal. The effect is similar to the crackle that can sometimes be heard on the radio or television when something like a fridge switches on and off. This radiated signal can be picked up by the other wires in the system and cause interference to the normal working voltages in the system

When electricity was originally used for practical purposes, it was used for communication in the form of the electric telegraph and the telephone. Petroleum and paraffin lamps were still lighting homes until the late 1800s, when Thomas Edison developed the light bulb.

If the screen is to be connected then make it off in the same way as for coaxial cable with a soldered pigtail and a sleeve.

It can become worn, warped and pitted over time. In order to correct this you will need a valve face grinder. These are expensive tools, so I recommend replacing the valves with new ones when you can. The rest of this article will assume you are using brand new valves.

Two of the phases are also connected to the transformer to power the logic. The start and stop buttons are at the left of the box (note: normally these are mounted elsewhere, and a separate layout drawing would be needed).

It needs to be cut with a valve seat cutter. A valve seat cutter is also an expensive tool but not as expensive as a valve grinder.

The combined cross-sectional area of all conductors and cables is not permitted to exceed 50% of the interior cross-sectional area of the raceway. The fill provisions are based on the actual dimensions of the conductors or cables used.

You can determine the amount of current being used and charged on your tractor’s system by placing the meter in-series with the circuits of the tractor. To do this: first remove your red probe and plug it into the 10 amp Max port on your DMM. Then set your DMM to DC Current with the range of 10 amps. Now you unplug the wire going to your ignition switch’s “B” terminal. By clipping alligator clips to your DMM probes you can now connect one probe to the “B” terminal of your ignition switch, and your other DMM probe to the wire that normally goes to “B” terminal on the ignition switch. Now when you run your tractor the current will flow through the meter and your DMM can give you a reading. It will tell you how many amps are flowing through your system.

Line diagrams, also called “schematic” or “elementary” diagrams, show the circuits which form the basic operation of the controller. They do not indicate the physical relationships of the various components in the controller. They are an ideal means for troubleshooting a circuit.
