Fried radiator fan and blown fuse

[nicknorth11]

I was out driving and started to smell something funny. Since I am breaking in a new build, I figured it was grease/oil left on the manifold from working. I then noticed my temps going up, so I decided to return home to check things out. I found the rad. fuse had blown and the rad. fan was demolished. the blade (white) portion of the fan was completely disconnected from the body (black) portion. The fan is what caused the smell.

My question is how can I test the system to make sure a new fan doesn't end up blown just like this one did?

You're probably going to have to use a volt meter to check and make sure the proper amount of volts are going through to the fan connector.

Correct. However, I would assume it was just your OEM fan failing and hence causing an overload in the electrical system. Check physical issues prior to another install.

The weird thing about the situation is that if I turn on my fans via ECMLink, my relays (I think it's multiple relays, at least) click open and closed. It could be just one, but I'm not sure. I'll unplug all but one at a time and see which ones are doing it, but does anyone have an idea why this could be happening?

if its a new build, then check to make sure everything is hooked up properly. maybe theres a loose ground causing it to overload the circuit.
