SOURCE: Wiring compressor

The two terminal cap is only for the new fan motor. Connect the compressor wire back where you found it, on the 3 terminal cap. It's the terminal marked, "herm". The "common" terminal on the 3 terminal cap must still be connected to one side of the 220 power at the contactor. One side of the 220 goes to the common on the compressor. The other side of the 220 goes to the run winding on the compressor AND the common terminal on the 3 terminal capacitor.

Please note. Not all installers use the proper color codes when they install or replace equipment. It may be necessary go go to the furnace or outdoor unit to verify what wires are for what purpose. Also be sure there are no splices in the wire that could change the wire colors between components.

  • R (red) or Rh (Red heat) 24 volts from equipment.
  • Rc (Red cooling) 24 volts from transformer in cooling equipment.
Note: If only furnace has a transformer and cooling equipment does not jumper Rc and Rh.
  • W (White) sends 24 volts to furnace control to start the heating cycle.
  • W2 (no standardized wire color, usually whatever wire color is available) controls second stage heat.
Note: W2 is most often used for heat pumps to control what is called emegency heat or Auxillary heat, and most often will use the white wire.
  • Y (yellow) often (blue) is used, controls cooling unit (outdoor condensing unit) also is used for heat pump heat.
  • Y2 (no standardized wire color, usually whatever wire color is available) controls second stage cooling.
  • G (Green) controls the fan "on" operation of the furnace/air handler. Also often is used to start the blower for many electric furnaces.
  • C (common) most often brown but can also be black or other color available to installer.
  • O (orange) Energizes heat pump reversing valve for cooling (Trane and most other brands).
  • B (Blue) Energizes heat pump reversing valve for heating (Rheem, Ruud and Weatherking).

SOURCE: i need the wiring diagram

On the fan relay hook up the red to r terminal the white to the w terminal and the green to the g terminal , now the blue needs to hook up to one of the two wires going to the outside condenser unit and the other going there goes on the c terminal . The blue does not have to go on the honeywell rrelay just wire nut it to the wire.

I need a wire diagram to replace an oven thermostat in a hot point RB 525 R2W electric range,please help!! I already have the new part I just need a picture of the wiring connected


If you have an exact replacement for the thermostat. Draw a diagram of the wires and the location of the connections take a picture of the thermostat with your cell phone. Then compare the drawing to the picture to be sure you have all wires .once you have them all . Then if you have wires that are the same color but hooked up to different connections. Simply place a piece of tape on one of them and make note of it on your drawing . then Unhook the wires and reconnect them to new thermostat. MAKE SURE THE POWER IS off at circuit breaker.

How to wire a relay.


A relay is used when the load you want to switch draws more current than the switch available for the application. For instance, you want to install auxilliary/spot lights on your off road vehicle. The ignition switch may not be able to cope with the additional 15 or 20 Amps required. Enter the relay. It uses a small current to supply a large amount of power from the battery to where you need it.
On the bottom of the relay are numbers stamped next to the connecting tabs, they are wired as follows:
  • 30 - Connected to positive of the power source(battery). Put a fuse in line with this as close to the power source as possible.
  • 87 - Connected to load. This would be whatever you want to power ie fan, lights, electrical motor etc. The other side of the load is connected to earth(negative of the power source)
  • 87a - Anything connected to pin 30 is routed inside the relay to thispin when the relay is off. When the relay is switched on, this pin isdisconnected internally from 30.
  • 85 and 86 These pins are used to switch the relay. 85 isusually connected to earth. 86 is then connected to the activation switch and the otherside of the switch is then connected to your power source. (It does not matter which way round you connect these pins polarity wise, since between these 2 pins is a coil used to pull in the contact points and as long as they have power across them, the coil will activate.)
Below is a typical application. In this case to power a radiator fan.When wired as below the fan will work only with the ignition switchedon and the radiator hot. (Thermo switch - v - activated) This is not only suitable to Jeep but Dodge, Volkswagen, Ford, Chrysler, any vehicle as long as you keep to the basic configuration.
Let's get some air over that cooling system. Referring to the diagram:
  • i is the battery
  • ii is a suitable fuse(see below)
  • iii is a suitable switch or in this case the vehicle's ignition switch.
  • iv is the relay (Beware, there are different relay pinout configurations but the numbers stay the same)
  • v is the load (In this case the radiator fan)
  • vi is a thermostatic switch mounted on the radiator
When purchasing make sure firstly that the wire used is of the correct guage(thickness/current rating) for the given application. You dont want the wire melting because it is too thin and cannot handle the current. Find out how many amps the load will draw and add at least another 20% for reserve. The fuse rating should then be matched to the wire's capability since it prevents the wire and power supply (battery) from overload and fire.
If you wanted to wire your headlamps by this circuit, iii would be the high beam switch. The headlamp "on" switch should be wired between fuse ii and relay pin 30. Low beam is connected to pin 87A and high beam to pin 87 instead of the fan. The thermo switch would of course not be needed and can be replaced with a wire straight from pin 85 to earth.

I need to find a hot wire that is controlled by the ignition switcb


Hi Bennie,

Since you didn't include a year, make & model bike, we can only offer general information.

You should obtain a 12VDC test light. They cost from about $5 and go up - and they look like this:
d156771c-dd6a-4b4e-9bba-53a78d5fb52a.jpg
The clip is connected to ground - either the - post of the battery or some unpainted part of the bike's frame. The tool end is pointed so that it can pierce the insulation of a wire with minimal force. Touch this pointed end to the battery's + post. The lamp inside the handle will glow brightly. If it does not, check the clip end to be sure is is firmly connected. If it still won't glow, check and replace the lamp inside the handle as needed.

Once the lamp glows as expected, turn the key switch of the MC to the position you want when you want power present. Carefully press the pointy tip into the different wire's insulation so that the point contacts the wire inside until you find one that causes the lamp to glow as it did when testing.

Next, turn the key to the off position and check the same wire for power again. If the lamp still glows, it means that this wire has power to it all the time, not just when the key is in that position. You will need to repeat the process until such time that you find a new wire with power ON when the key is in one position and OFF when the key is off.

Depending on the load you want to add, if small enough, you might be able to tap off that wire. Loads such as a stereo's memory protect wire (saves stations stored in memory and keeps the clock running) could be connected directly as they represent a very small load. If a large load - or unsure of the load, you should install a relay instead. They look like this:
8a34b959-fcc2-4839-9a8c-5a56d4dcf63d.jpg

With a relay that looks like the one pictured; let the switched power wire provide power to one side of the relay COIL terminal (85). Connect a good ground or 12 (-) to the other side of the relay COIL terminal (86). Run a wire from the 12 (+) battery post to the relay's COMMON terminal (30) and connect the load or device's 12 (+) wire to the relay's NORMALLY OPEN terminal (87). If for some reason you want power available to some other device, but ONLY when the key is OFF position, you could connect it to the relay's NORMALLY CLOSED terminal (87a). There's isn't much need for doing this, but I included it anyway. Remember, power on (87a) would be OFF when power is on at (87).

I hope this helps & good luck!

Have two Broan exhaust fans that I want to wire to a programable hvac themostat.I'm told that I need a relay and not sure how they are wired. The fans draw 1.23 amps each and looks like they have


are you sure that your not looking at motor capacitor attached to each motor??? To use programable stat you would have to find line voltage stat with rating to handle fan amp . other option is to use low voltage stat and transformer and fan switching relay with fan motor wired through n/o contacts and relay 24v coil energized by low voltage stat.

Trying to replace the start relay on my Roper refrigerator.


depending on the model and the part # of the ptc overload relay will tell you how to wire it back as was,on some ptc O/L's there are spaces on the component where you just plug it on piggyback to this ptc,if not then all you do is wire the capacitor in parallel to the 2 power pins on the compressor,the cap doesn't actually start or run the units compressor,its there to help suppress the arcs on the relay when it starts,the compressor will operate without this capacitor

2002 aultma 2.5 will not crank when turning the key


Well there are several things you can check if you haven't already. I'm just starting from point a to point b to narrow things down. If you have already done a certain step, just skip and go to the next one. The first thing to check is a fuse in the fuse panel inside the vehicle (see picture's below). I marked the fuse you need to check (#12) The second thing is to see if you are geting power as the key is turned. While you are down at the starter, have someone turn the key as if to try and start the vehicle. While they are doing that, at the grey connector (I think it's grey) check with a test light at the black & white wire. You should have power there when the key is turned to start. If no power there is a relay/fuse panel that is kind of hidden. It's called (by Nissan) the IPDM/ER (intelligent Power Distribution Module/Engine Room).Below are step by step instructions on its location and how to remove it. In the last picture is a diagram of the fuse and relay layout. I have marked the starter relay as well as a fuse you will want to check. After you check the fuse, you can have somebody turn the key as if to start the vehicle. While they are doing that put your finger on the relay to see if you feel it "click" inside. If it doesn't the relay may be bad. If it does find the black and white wire coming from that harness to see if you have continuity from there to the grey connection at the starter (black & white wire) if you do check for a bad ground. If you do not find the break in that wire and repair. The only thing that I am not sure of is in the 2000's at some point the relays in the IPDM/ER were not replacable and the whole thing needed to be replaced. I'm not sure your year vehicle has this issue. I know this seems like a lot but you have to narrow down everything in order to diagnose the problem to solve it. Hope I was able to help and good luck.

Not sure how to wire Supco RO41 Relay/Overload Combo to Maytag side by side Fridge MSD2454GRW. It's a universal part, so it's different than the manufacturer's part, but I just want to see if...


while i loath those RO41 because your compressor will be dead SOON. The 2 black wires connect to the wires were connected to the wiring on FACTORY RELAY AND OVERLOAD WHICH WAS ORIGINALLY CONNECTED TO WHERE THE RED/WHITE/AND BLACK WIRES WITH THE TERMINALS NOW ARE.

my advice though is throw that thing in the trash and get factory OEM relay and overload

FUEL PUMP FOR CHEVY SILVERADO


fuel filter? how about power to the fuel pump,loose ground wire to chasis? wiring harness? terminals clean at point of connection?did you check the fuel pump relay? Relay is located in electrical center under the hood on the driver side.relay and fuse legend will be on bottom side of cover, you sould be able to switch with another relay that you know works, ie: switch horn relay with fuel pump relay, honk horn to insure both relays are working when either relay is inserted into horn slot. Do you by chance have the electrical schematic drawing for the fuel pump?
