How much power does a relay use ? I mean how much does it use to activate ? Thats very little current right ?

 

I still can't figure out where it is you guys are talking about getting the wire from the switch out to the relay(from inside the cab to under the hood) maybe if it wasn't 38 degrees and 15mph winds I would have an easier time. I have had the lights up there so long and had a little bit of rough start hooking these lights up its starting to get on my nervous, and I am starting to get mad at myself for not being able to get them done yet.

I feel better now.

 

I f you open the hood and look to the back right hand corner where the fuse box is look under it on the firewall you will see a black rubber oval lookin thing with wires comin out if it and you can just pull that off and poke a hole and pull the wires threw there, if that is what you are talkin about let me no and i will go take a couple of pic of mine so you can see.

 

It depends on the impedance of the relay's coil. Typically they are rated at something like 75 ohms. So on a +12 VDC nominal circuit, that would be a draw of 12 VDC / 75 Ohms.. or about 160 mA.

And I think that's the worst case. I believe that some relays may actually offer more impedance than that.. more like 200 Ohm.. which would result in a 60 mA draw.

Yes, that's very little indeed. At least for automotive applications.

Edit: Although asked for power.. didn't you. 75 Ohms on a 12 VDC circuit gives you 12 VDC ^2 / 75 Ohms.. or ~1.92 Watts.

 

your kidding me right?!.....look at the bloody pictures if you cant still figure it out I will have you call me in a little while and make you go outside lol...

 

What exactly is this thing called. Mine just broke on my 95' and I need to buy a new one so I am trying to search for a new one online to get price ranges..
