Another Derale fuse holder failure
Yep... Plenty of cheap DC clamp meters available and they're very handy to have.
But if the fan runs 25A and your fan will be on a lot, then you absolutely need better wiring setup.
I'd never want a continuous load higher than about 2/3's the rating of the fuse and holder.
And if you want good quality blade fuses, go to a junkyard and get them from a cars original fuse box. Most aftermarket stuff is just cheap chinese *****.

I just went and bought some high quality 40 amp fuses and upon removing the ones that came in my Derale kit I noticed right away that the tangs on the new ones was way thicker than the cheapies. I also checked against the 30 amp ones and the new 30 and 40 were the same thickness with the cheapies being super thin. I could defientely see the entire fuse getting hot and melting the holder without ever blowing the fuse itself. Time will tell if my theory is correct lol.
I've heard of people having issues wiring it that way and initially I was going to do the same but was talked out of it. How long have you been running it that way and do you experience high temps where you live? Cheers.
I wouldn't recommend using the factory wiring.
So far, no issues. But VERY limited time.
My fans wouldn't run after awhile hooked up this way. We tried it and the car was getting hot, and turned out the fans weren't running. Wired them up on separate relays using the factory trigger for the high speed and haven't had an issue since.

2 Brand new Derales in the car I just finished, less than 5 minutes run time, 1 fused melted but the other was fine, cut both out and replaced fuses and fuse holders. Both were wired to the same power source, all connections crimped and soldered.
