Electrical Troubleshooting

CASS EO (electro-optic)

Yes, a transformer has eddy currents.

Yes, you will need to install a second 12V battery in series with your existing 12V battery to supply 24V to the winch. However, to keep them charged, they have to be charged in parallel. You'll need a schematic to do this correctly and not damage the winch or batteries. I recommend you contact the winch manufacturer for a schematic. It might be best to purchase two new 12V batteries to operate the winch and not tie into your Land Rovers battery. I would purchase "deep cycle" marine batteries such as are used in boats and RVs. These will give you the best performance They are available anywhere batteries are sold.

You have to employ the microphone jack on the amplifier providing the signal to the speakers. If you don't have a mic jack on your amp, your out of luck.

Briefly, a megger test is testing an electric circuit at load. The circuit might prove good at normal resistance measuring but fails when applying high voltage. Read the megger result correctly, every electric circuit will fail if stressed high enough. Disconnect any servo drive or frequency controller before testing.

In the wall beside the sink and always in accordance with your local Wiring Codes or Wiring Regulations.

In a location next to a kitchen sink a Ground Fault Circuit Interrupter (GFCI) is likely to be essential to meet the latest wiring and personal safety requirements.

The very first thing you do is shut the power off to that circuit if you are going to work on it. A regular duplex receptacle has 5 screws on it. With the receptacle facing you and the U ground pin facing down, the left side (neutral blade, silver screws) connects to the white (neutral) incoming wire. The right side (hot blade, gold screws) connects to the black (hot) incoming wire. The ground wire connects to the green screw on the receptacle Strip and wrap the wires around the appropriate screws. This leaves you two more screws on either side, tighten them snug as no wires go under them. Reinstall the receptacle back into the wall and turn the power back on.

Well work out your CSA size from what you got. If you've got the wiring regulations you can look it up there. Takes some time but you'd find most of it in there on what you need.

Sounds as though you only ran a 110 volt power supply to your new shop subpanel. You need to supply 220V with a neutral and ground from your main panel to your subpanel. The 220 supply needs to come from a two pole 220V circuit breaker in your main panel. (example 50 or 100 Amp) Then, most importantly, you must use the correct size wire to carry the current. That is the wire must be sized correctly to the 220V breaker. The neutral must also be the same size as the conductors.

Once you determine how much power you need in your shop, size the supply 220v circuit breaker and wire accordingly. Check with your local building department if you are unsure or what size wire to use with what size breaker or refer to Table 310-16 in the National Electric Code.

In Australia domestic power is 240v So you have run single phase power to a three phase switchboard. To get power to those breakers you must hook the active to the busbar connected to those circuit breakers.

Most likely 110-120 volts AC

Because to much electricity is getting through to the light bulb.

It depends on the voltage of your electrical system. The basic formula is watts = volts X amps. So, if your voltage is 120V then the absolute maximum watts available would be 3600 (30 * 120 = 3600). Note that this is the point at which the breaker would trip, so you could not count on 3600 watts for more than a few minutes. A good rule of thumb is to limit your normal load to 80% of the maximum available. In this case, 80% of 3600W is 2880W. If you put a frozen dinner in the microwave for 5 or 6 minutes and happened to push the watts up to, say, 3500, you would probably get away with it. But try the same trick with the air conditioning that runs for an hour or two and you will trip the breaker. Keep the watts below 80% and you can run forever.

VATS is usually a GM (General Motors), system for helping prevent vehicle thefts.

There are several different procedures depending upon the year and make of the vehicle. Search the internet for "VATS Bypass".

I bypassed the vats on a 1996 Buick by accessing the wiring diagram for the VATS. I measured the resistance of the key chip. There are 15 different values it can be. It is simply a resistor. In this case, the chip measured 3000 ohms. I went to Radio shack and got a combination of resistors that would give me 3000 ohms. There are 2 wires that come out of the VAT module and go up the steering column to the key switch. I located the VAT module behind the glove box. I cut those two wires and soldered the resistors in so that the module always saw 3000 ohms. You have to solder the resistor on the module side, not the key side.

When dealing with HVAC systems, notice that there are two systems at work, and two possibilities for failure: the HVAC control system, and the actual HVAC unit. Determine if your problem is in the function of the controller (blank screen, not turning on, relay does not click on when fan or thermostat is set past current temperature), or in the HVAC unit (thermostat relay is clicking but HVAC fan does not turn on, condenser outside fan is not spinning, etc.) If the air conditioner was 'grounded', as I understand it, I would think your HVAC breaker would trip. This should help you figure out your problem.

The likely problem is the setting of your pressure switch. These models differ and you'll likely have to locate the manual for your switch. The manufacturer and model will usually be listed on the pressure switch case. The dump valve will likely do nothing except cause the air to be released in case of overpressure. It won't cause the compressor to shut off when it should.

The general answer is that a continuity tester is used to check for an open circuit.

One possibility is the manufacturer of that particular board. Many have repair/exchange programs. If the board itself is physically broken and/or burned, it is probably not repairable. If components on the board are bad, it may be repaired. One possibility is the manufacturer of that particular board. Many have repair/exchange programs.

You shouldn't have to clean the contacts. If they aren't working, it's often due to damage from arcing. However, you can use compressed air, air in a can, or electrical contact cleaner, only after the main bus is de-energized and the breaker is removed from the panel. Contact cleaner is a liquid, and should not be sprayed into a live bus or breaker.

The VOM is in the classification of a multimeter. This means that the one meter can do several functions. VOM stands for Volt Ohm meter. In the voltage portion, the meter has the ability to measure a variety of voltages from fractional usually up to 1000 volts. This is both AC and DC voltages. In the ohms portion, the meter has the ability to find the resistance of components. On most good multi meter there is a continuity setting that will have a sound emitted if what you are testing has continuity through it. That setting is very useful in troubleshooting control panels to locate open and closed contacts in energized and de energised relays.

The heat generated by any particular resistor depends (at least electrically) solely on the power it dissipates. Power dissipation in a resistor is equal to current squared times resistance, and the current through the resistor is equal to the voltage across it divided by the resistance. If we take a 10 ohm resistor ('your resistor') and put it in a series circuit such that there is 10 volts across your resistor, the current through it will be 1 ampere (10/10=1). the power dissipated will be 10 watts (1^2 * 10=10). If we put your resistor in a parallel circuit that also puts 10 volts across it, then the current and power will be the same. Your resistor does not know or care where the voltage came from. From this point of view, once you get down to the voltage across the resistor, it does not matter what type of circuit it is in. On the other hand, for any given power supply voltage, then the type of circuit and the value of external components certainly does affect the terminal voltage and thus the current through as well as the power dissipated by the resistor. In a parallel circuit, the voltage across your resistor remains basically the same no matter what resistance you put in parallel with it (unless you overload the power supply or the power supply has high internal resistance). In this case, the voltage across the resistor is the same as the power supply, current is I=E/R, R being that resistor only, and power is P=I^2 * R. In a series circuit the current through the resistors is I=E/R, R being the total resistance (including the other resistor(s)). The power dissipation in your resistor will then be P=I^2 * R, I being the series current we just calculated, and R being your resistor only. Since the other resistors affect the current, and since the current is the same no matter where you measure in a series circuit, then the voltage across your resistor and thus the power dissipation will be affected. The voltage across your resistor will be E=I*R, I being the series current we just calculated, and R being your resistor only. So, while the calculation for power dissipated in a particular resistor does not change relative to what type of circuit it is in, the calculation to arrive at the voltage across the resistor and/or the current through it (which you will then need to calculate power) does. Keep in mind there are other mechanical parameters that influence the actual case temperature of the resistor. Physical size of the case, composition, and airflow velocity, if any, will alter the case-to-ambient thermal conductivity. Ambient temperature will also be a factor in the final temperature.

A high pot test is a test of a wiring system for high potential (voltages). It's also called a megger test. This test verifies the integrity of a wire's insulation, and ensures that high voltages cannot escape through cracks in the insulation smaller than the human eye can see.
