OpenLab Relay Hook Up Guide

By the time you are done with this Instructable, you should have a good idea how it should be done. Add Tip Step 3: The Relay Connection For those not familiar with relays, here is a quick intro. A relay is nothing more than a switch that is activated by applying power to two terminals connected to the coil inside the relay aka energizing the coil. When the coil is energized, it acts like a magnet this is how all electromagnets work and a relay is no different.

When there is no power to the coil, the contact blade is in itsnormal position.

They call it the RIGblaster Wait!!! One with a virtual consol? The Kachina, Pegasus or whatever? If you are a FT MP owner, look no further. This great site is a one stop information authority and missing it will be your loss. First off, keep it as simple as you can. Since the decimal point was not showing up too well in cases like 4. It follows therefore that without the attenuator, microphone input overload can result, causing the normal narrow bandwidth to increase dramatically producing unwanted splatter.

Try this hook-up first. If you are operating clean and you are having no ground loop problems, that’s it. There are a lot of Hams who operate very well using just this circuit. Well the next step is to isolate your sound card from the radio. To achieve this, check out this well proven schematic shown at right. Radio Shack does have transformers available.

Just type and press ‘enter’ Search for: The schematic of an automatic cooler fan for audio amplifiers is given here. The circuit automatically switch ON the cooler fan whenever the temperature of the heat sink exceeds a preset level. This circuit will save a lot of energy because the cooler fan will be OFF when the amplifier is running on low volume. At low volume less heat will be dissipated and it will not trigger the cooler fan ON.

The temperature is sensed using an NTC negative temperature coefficient thermistor R2.

Does it matter if I hook it up at all? Most of the other transmissions used a mechanical linkage or cable to indicate wide-open-throttle WOT. This WOT trigger achieves two things: Above a certain speed, as determined by the governor, the transmission will not downshift from third to second or second to first gear. This is to protect the transmission from damage. Instead of a linkage or cable, the TH uses an electrical switch that is most often mounted on the carburetor.

When the linkage hits WOT, this completes the circuit to connect the transmission to full system voltage. This electrical input powers up a solenoid in the transmission that accomplishes the same results, with higher line pressure and a signal to downshift the transmission. Often when a TH is swapped into a different vehicle, this downshift electrical switch is overlooked.

Besides the loss of any kind of downshift function, the real danger is that under WOT the transmission has not been commanded to increase line pressure. This causes not only a soft upshift, but also damage to the clutches because the lower line pressure increases the potential for slippage on upshifts. There are several ways to solve this problem. The factory used a switch located on the carburetor or on the throttle linkage under the dash that at WOT supplied voltage to the transmission.

What you will learn in Thermostat Wiring Colors Code article: What thermostat wire color is likely to go to which terminal on the thermostat. Basic electrical safety and standards for wiring color The function of each wire terminal on the average thermostat. Additionally highlighting some of the differences in those functions from manufacturer to manufacturer.

Wiring a SPDT Relay. Ask Question. up vote 2 down vote favorite. I am new to Electronics and I am currently trying to wire up a SPDT Relay. I must admit I am totally confused. I want to have a SPDT switch that simply switches the relay over. Any pointers would be appreciated. When I currently energize the relay, I hear it cycling, which I would.

Tried that as well, no luck. I tried it both with the Y from the thermostat and the line to the relay attached only to each other and with them both attached to the Y on the air handler as well. If you don’t have one, go buy one, you need it to diagnose what’s happening. You might as well use this control voltage since you would want the evap cooler active when the fan is on. Measure the voltage at the fan relay to ensure it’s 24 VAC remember this value.

Run wires from the green wire to your relay and also connect the common. Does your relay activate when the fan turns on? If the 24 VAC transformer can’t handle the extra load, it may not turn on the fan. What is the voltage at the fan relay now? Alternately, you could replace the fan relay with a 2-pole version to give you the extra contacts for the evap cooler while only using a single relay. Thinking about this again, use the cool control since you do not want the evap cooler on during heating mode.

Or stay with the fan signal and place a normally closed relay in series wired to the heat signal. That way you would have evap cooling any time the fan is on which you want for cooling and the evap cooler is off during heating operation.

Manufacturer blames Super Bowl outage on incorrect setting

Alde wet heating on gas 5 Caravan mover See text From the table you can see that modern flat panel TV’s are quite economical and that tthe newer LED backlit ones are even more efficient. Do make sure that the one you buy can be run directly off 12 volts. The table also shows that fluorescent lights use less power than halogen lights and that LED lights are more efficient again. Some are even available as direct replacements for the spotlights found in more recent caravans.

Clearly, swapping to this type of lighting is going to make a significant impact on battery life, especially during long dark evenings.

I came to this page looking how to hook up the relay (just the component, so this post doesn’t help me much). No relay (as a component) has a “signal” pin on the coil side, just two pins (which then need additional circuitry for load and spikes regulation).

Remove the PCM from its mounting bracket and unplug the wiring harness, which is held in with one screw. Unscrew it and slowly wiggle it side to side until it comes loose. You will need to insert a pin into an empty slot, pin 42 on the side that says “BLUE”. Carefully remove the blue plastic cap on the side of the harness that plugs into the PCM.

Sorry, I didn’t get a picture of that Here is where you need to insert your green trigger wire pin. The empty spot labeled I poked an awl thru the yellow rubber to make it easier to get the pin thru. Here is the inner side with the blue cover removed. Now take your pin, and carefully push it thru the pin 42 hole until it is fully seated just like the rest of the pins.

Now you need to mount your relays. If you are using a Blackbear harness, you can mount them wherever you choose. But I have the OEM harness, so I am putting it right alongside the fuse block, right where it sits on a truck. It just clips right in.

There should be 8 of them. Here is where most people get confused. The pulley that your fan is attached to stays there. You will not need another belt or anything like that. You may need a fan wrench.

Volvo Dual Speed Fan – Homemade Relay Circuit: Here is the equivalent relay wiring with two standard Bosch-style relays. Note the primary function is to allow the 2nd (low-speed) relay to disengage when the 1st (hi-speed) relay engages.

Andrew Krause Relays are one of the oldest, simplest, and yet, easiest and most useful devices. Before the advent of the mass produced transistor, computers were made from either relays or vacuum tubes, or both. A relay, quite simply, is a small machine consisting of an electromagnet coil , a switch, and a spring. The spring holds the switch in one position, until a current is passed through the coil.

The coil generates a magnetic field which moves the switch. You can use a very small amount of current to activate a relay, and the switch can often handle a lot of current.

Use F11 to go to full screen viewing if using Google Translate. Cooling Fans Although many people are now using cool-running class D amplifiers to power the subs in their vehicles, those amps and the class AB or class B amps that they’re using for mids and highs can generally benefit from forced air cooling. It’s obvious with class AB or class B amplifiers because the heatsinks get so hot but not all of the heat in all amplifiers is transmitted to the heatsink.

Many of the class D amplifiers have circuitry that operates at such high temperatures that the electrical components actually damage the circuit board over time. Even those with internal fans fans that do not pull fresh air into the amp are only moving around hot air and getting a bit of cool air into the amp can make the amp more reliable. Generally, you want to force cool air through the fins of the heatsink.

Nov 26,  · thermostat hook up ok still not getting anything,,,,,here`s how it got hooked up red wire from thermostat 2 red wire from furnace, then a jumper wire from the red at the furnace 2 the relay -#4 open. the w wire from the thermostat 2 the red on the aqustat.

Someone with more control knowledge might help you if you want it all on one thermostat and it will have to be the correct model for doing that. The boiler is set at 74 and the gas is set at 70 or something. If the wiring and control is totaly escaping you you might want to invest in a furnace man for a few hours but you need to be able to tell him exactly what you want done which is simply switch the fan on high speed and off with a thermostat for the boiler heat and the gas furance and control gets left alone.

Now I dont want to add to your confusion at this point but the one and only potential problem with this type of control is that if you let the fire go out on the boiler the fan is going to run continuously as the thermostat is going to be calling for heat that cant be delivered, Got it? The gas furnace will still cycle its burner to maintain the heat setting of that thermostat but the boiler ‘stat is going to keep the fan running all the time.

This would be the only reason I can think of to have the second aqua-stat mounted somewhere to sence heat in the exchanger. No heat in the water, the fan cant run. For all the added complication I just plan to keep the fire going. If it goes out then I can shut the fan on switch to off or simply turn the boiler thermostat down and the fan quits running except when called for by the gas furnace.


An open circuit, obviously, is a broken or disconnected wire. Shorted circuits occur when the insulation between two wires fails. Before wasting hours of expensive diagnostic time, test all fuse circuits with a DVOM or approved test light. Remember that fuses can fail without showing signs of an obvious burn-through.

April 29th, Wiring An Electric Fan with Two Relays. After having my new Walker radiator installed with a inch electric fan, I was very dissatisfied with the wiring situation.

Would you like to merge this question into it? MERGE already exists as an alternate of this question. Would you like to make it the primary and merge this question into it? MERGE exists and is an alternate of. Merge this question into Split and merge into it SAVE In Car Batteries , Jeep Grand Cherokee Laredo Yes, you can power the fan from the battery momentarily to see if the fan works, however powering it continuously from the battery is a bad idea.

I rigged my fiancee’s so it would run when the key was on I thought I was saving the time and money to replace a relay which is notoriously unreliable Long story short, the fan had a bad bearing, the relay was bad and I ended up replacing them both along with the battery. I was just looking at this site because the fan will now not shut off even with the key out. The problem is the sensor-computer-relay-fan path.
