Not much shop time today, but I'm studing the schematics and planning while watching the race. 13 cautions and just half way thru. Questions: Is there any reason why I can't keep the relay inside the cab? I know the reason for a relay is the reduce the bigger wires from being in the cab. So that means I need to keep it close to the battery. I just don't want a lot of wires in the engine bay. Info: I am running a single fan with two terminals. Fuse panel Spot #1 to one side of the temp sensor included in the relay package. Then the other wire from the sensor to the yellow wire of the relay. Spot #2 unsure what to connect there if anything. The only thing I can think of is the ground wire from the fan or the ground from the relay. Relay Red wire- to the battery. Black wire-to chassis ground close to the battery Green wire- to the AC controller, which will be discussed in a later post Orange wire- power to the fan with the fan grounded to the chassis. Let me know if I'm getting close to having it right. I don't want to wire up something I'm not sure of and have to redo it. Shannon and I went junkin' today and I picked up the connectors for brake lights. Ok my brain is smoking. ;) |

Side question,
You posted this in another thread. Do you remember what brand support brace you used here?: Quote:

Has any body looked at my wiring question 2 post above? |
Re: Project Vitamin C-10
I would mount the fan relay close to the fan. Not in the cab. Run a temp switch to turn on the fan, or a switch where ever you want.

Thanks guys, I'm going to repost my question for clarity. ;)

Re: Project Vitamin C-10
Alan , Just got home, This working for a living screws up my free time :chevy:
1) the relay is usually located close to the power source and the load as Dennis mentioned. The relay could be hidden be behind the grille off to a side out of view if you wanted. Keeping the relay close to the load keeps the voltage drop to a minimum with the heavier wires doing the work and then the smaller gauge coil wires running back to the cab to turn things on and off. 2) I think you have the right idea with the plan , I am not sure what you mean by spot 1 and spot 2, Would that be the terminal location from the terminal block(panel connection block)?? I cannot quite make out the terminal numbers on page 1 But with a single fan you would only need the one output from the N.O. relay contacts to the fan motor. 3) use a good grounding method, I like to extend all the ground wires to a common area and ground them together and then to the frame or back to the battery or block. I have found on old cars and especially trailer lights, most electrical problems are really grounding problems, Now, looking into the future,, Are you planning to run the high and low beam relays for your headlights??? maybe they all can be hid in a shiny junction box or concealed in the same location behind the grille or headlight bucket area???, |
Re: Project Vitamin C-10
Not to confuse the situation, but I use relays to ground also. I did that with air bag compressors, and worked great. No come backs or melted wires.

So do I need to connect anything to the terminal #2 on the fuse block? It's showing a switch or sending unit to ground. I don't think I need to connect anything there. |

Re: Project Vitamin C-10
Sorry for that. :haha:

Re: Project Vitamin C-10
Instead of powering the compressor, I use the relay to switch on the ground. Make sense? :mm:

Re: Project Vitamin C-10
Lots of progress, looking good!! I'm still not getting notifications on your thread like I used too so I forget to stop by more often

Re: Project Vitamin C-10
After I commented, I started to think. I'm about to wire up the fan on the 57 Panel I'm working on. Here's American Auto Wire's diagram. I'm going to install the relay close to the fan.

Re: Project Vitamin C-10
I made these diagrams to help my customers.
This is how I wire up a compressor for air bags with the relay switching positive power. It can be used for cooling fans also. http://belair.smugmug.com/Other/Kust...1050696-XL.jpg This one is with negative switching. I think it works best for higher amp draws. Use a 30/40 amp relay. I never had overheated wires or terminals this way. http://belair.smugmug.com/Other/Kust...1050694-XL.jpg |
Re: Project Vitamin C-10
Just a quick note, I'm not getting all the notifications either from any threads. I think I got two notifications all day from other threads. It's really sporadic.

Re: Project Vitamin C-10
I get all the notices. No problem here. ;)
Maybe it your Smart Phone settings? |
