my e-fans are run with a derale relay the fuse inline to the 12 volt power source is totally melted why do you think that happened. short? power surge?

 

What do you use for your power source? Did you wire the relay to the battery or...?

Which e-fans/kit did you hook up?

 

What gauge wire are you using?

 

It's not uncommon with inline fuse holders protecting relatively heavy loads -- if it's the common 3AG inline holder with 14AWG or 12AWG wire, you'll just need to replace it with something that's got more meat to the fuse contacts and bigger wire.

 

Wow. I was going to reply again with the question of wire size, and found two others mentioning that a minute or less behind me.

 

it's a derale e-fan relay kit that came with my fans, (procomp) ebay. It would run 200 in the shade and would shoot up to 230-250 running. id have to shut her down, and let her cool. replaced the t-stat to day and was still running hotter than it should. i figured the fuse inline to the relay was too small took a look and wow. So I wet to wally world and bought an inline fuse kit, should I do this or get another relay. Also noticed yesterday that the temp switch that turns my fans on wasn't working, I had to leave the toggle switch on. the 12v source was wired to a junction, the I removed it and moves it to the battery

 

what temp should i be running at i thought 200 or less. the block is bored .020 over and was told this would make it run hotter.

 

the fan ground came loose then grounded out the fans

 

That'll do it.

Don't run smaller than 10 gauge to an e fan. That'll give you a minimum of 27 amps continuous load. If the fans take more juice than that, you need even bigger wire.

I also do not think a crimp only connection is good enough for a fan setup. You need to either solder the connections or use crimp and heat activated adhesive terminals and butt connectors. There's just too much vibration in both the fans and the vehicle to hold crimps. I learned that the hard way too.

 

Ill also add that there is no such thing as overgrounding your vehicle. If you're concerned about it, you can run 2 ground wires to 2 separate points.
