E-Fan fuseholder melting
What would cause this to happen?
Im aware of 'L2en' E-Fan/ battery meltdown problem not sure though if this could be the same.
I havn't used the truck in 3 weeks(iv been away) and went to start it and the Optima is dead so i get the charger open the hood and i see this;
The fan(Black Magic) still works and obviously the fuse is not blown

pastfinder(sp?) had this happen recently and posted pics on the "E-fan announcement"
One more pic for me to show TorqFlo/CompressorWorks

Black Magic model #40 by Flex-a-Lite.and i don't understand how that could get hot enuff to melt the holder but not blow the fuse, BTW the fuse is within 4" of the 'hot' as someone mentioned in the other post to have it as close as possible.
Her's the new holder a little heavier gauge wire and holder;

That would be me :) Here's what mine looked like...
I cut out the fuse and added another one for the mini style fuses. Works fine now.

I agree 100% with FireRanger's comment about high resistance connections in cheap inline fuse holders. A high current circuit like the efan deserves the best fuse holder you can find.
This is a somewhat crappy photo, but you can see how the fuse is misshaped and the plastic inside the holder has melted a bit (shiny). I just added a mini 30Amp fuse holder and it makes a HUGE difference in the efan performance :)

I looked at a few fuse holders that I have and one looked a lot like that one with the folded over edges on the internal terminals. The others had more substantial looking terminals made of heavier metal that looked like they would have much more contact surface area and a tighter fit. The heavier terminals are similar in appearance to the terminals used in an OE Ford fuse box.

wow, i also had changed my mind about the efan.....If i did have one i would probably be returning it....
Seems like it should be a smaller fuse? Maybe like a 10 or 15 amp? Maybe that 20 amp is too big and its letting stuff get heated too much.....either way it should have popped but, being 20 amp it might let enough go that it could melt...

This has nothing to do with the fuse size or the wiring or the fan. It is just a crappy fuse holder.
maybe corrision did build up on the connections, anyway it's somthing im going to now check and pull the fuse to look for any buildup on the contacts and replace sooner than 5 years, LOL.
Thanks to all.
