electric fan help
 

I need to install an electric fan into my Polara and the one I bought came with no instructions. It just has a couple wires with a plug, some plastic pieces, four of them are long threaded ties with a flat black head, and what look to be some sort of clips. no bolts or washers. has anyone installed one of these before?

You have to be joking right? Two wires, Positive and a Negative. Hook them up accordingly with a relay and a switch, VOILA. Cookin' Beans. As for mounting.. does your rad have any sort of mounting areas for the old shroud? use them as the electric will not utilize a shroud.. and then you should be good to go. Do you need a diagram how to wire a Relay up?

Not Joking, I am an electrical tard. I already mounted it but a diagram of how to wire a relay would be great! It has a connector on the wires but I think I will cut it off and just use the wires since I have no idea how or where to find the appropriate adapter and/or how to wire that. I figure just use the wires and cut out the middle man, right?

Here I drew this for you :)

It should be pretty self explanatory. Hope it helps. Use a 40a or 50a relay and you will be set. Goodluck

Damn good illustration! Can you draw an internal picture of how a relay works? That may help some folks understand how they operate.

I thought that would have been a good idea when i read your post as well, when i found a really good picture already made.. and exactly how i was gonna portray it :) lol.

Here is the picture i found. I will go in to some detail on how it works now.

There are five terminals; two to "activate" the relay and the other three are the "switching" terminals. As you can see in the picture above, there are three terminals that are facing up and down, and two that face side to side. For reference, we will consider the uppermost terminal (#30 facing up and down) to be the "top" terminal. Now that we have our orientation, it's time to understand which terminal does what. The two side terminals (#85 and #86) are the "activation" terminals and have no polarity. They simply require +12 volts on one and ground on the other to activate the relay. The terminal on the top will be the common "switching" terminal. This means that it will be the one which is always connected to one of the other two switching terminals. When the relay is not "active," the top terminal is internally connected to the middle terminal (#87a). As soon as the relay becomes activated, the top terminal will break it's internal connection to the middle terminal and become connected to the bottom terminal (#87). Essentially it's just like flipping a normal switch, only its flipping action is controlled from a remote source.

Wow! thanks for the help. I will let you know how it turns out.
