Fuse question
Posted: May 12th, 2012, 1:39 pm
Under the hood of our cars there's a fuse box that says (AD FAN) 40A and ABS 60A. What does the AD FAN do and is it normal for the fuse to be blown from age?
Your totally fu@ked dude. What the hell are you saying here. Stop responding if you have no idea what your talking about. Seriouslywednesdayslatest wrote:any fuse will blow from age
and the AD FAN is probably the addition fan or the high temp fan that goes on second when the engine is really hot, usually it doesnt need that i got my first fan on a switch and i dont ever need the 2nd one
I sent him a warning. If he keeps on posting I think I'll just have to ban him. I think this might be some underage kid posting.Daninski wrote:Your totally fu@ked dude.

"AD FAN" stands for "Additional Fan", referencing to the cooling fan for the Air Conditioning, so obviously you must have A/C.
Like anything, a fuse can die from age/use, but really, it's a non-issue, don't worry about that. What I would look more into is the actually A/C Fan. As electric motors start to wear, they have a hard time and start to draw more and more current (amps), where eventually it would draw more than the fuse protecting that circuit, and pop it. It can also fail siezed and a very high resistance, create a short, or just fail open, but the latter wouldn't cause a blown fuse.
There are 2 versions of the main cooling fan, one is a single speed, another is a dual speed. If I remember right, the dual-speed was for the automatics, while the single speed is for the manuals.
Maybe, maybe not, you don't know this. You can have fuses in your car for 20 years that will never blow in the life of the car. Last year, I had 2 fuses blow in the truck, one for signals, the other for the brake lights. I replaced the fuses, and it never happened again. Maybe it's a bulb that cause the problem, maybe it's the fuse that decided to let go, maybe I had a surge in draw in the electical system and those are the ones that popped, there's no way to know unless it happens again, AND your monitoring it where you can replate it blowing to a specific scenario or event.wednesdayslatest wrote:and i was right about the fuse and its fact its not lifetime it WILL blow.
“Does Cooper Bussmann provide, or have, MTBF data for its fuses and holders?”
Cooper Bussmann does not have or provide Mean Time Between Failures (MTBF) data for our
fuses and fuse holders as they are passive devices. As such, they remain passive until an
overcurrent event occurs.
When an overcurrent event occurs, the fuse opens as designed and interrupts the flow of current.
This is not a “fuse failure,” but a proper function of the fuse design.
What are perceived as fuse and/or fuse holder “Failures” are mostly reactions to excess heat
produced by loose or corroded connections, improper component sizing or application outside the
devices’ operating temperature range. These are not device failures, but rather inappropriate
device selection.
Fuses do not require maintenance until an overcurrent event causes them to open – then they
need replacing. Although not always necessary, an infrared inspection every 3 to 5 years is a
good practice. This would reveal any excess heat conditions that are most apt to cause a
nuisance fuse opening and should be addressed.
That's horrendous advice! All you're doing is bypassing the fuse with a piece of metal. You can do that with any type of fuse, and it's absolutely dangerous where you can cause damage to your electrical system or worse, cause it to catch fire!wednesdayslatest wrote:the old fuses the glass ones (not the ones for this car) you could wrap with tin foil and theyll never need replacing again, at least thats what this old guy told me but thats for old cars with thos types of fuses

This is no joke, and a serious danger, never, ever, EVER, EVER! replace a fuse with a piece of metal or a larger value fuse, unless it's very temporary and it's to get you out of a hard jam. Remember the fuse blew for a reason, cause 98% chance there's a problem in that circuit, and by bypassing the fuse, your taking the safety out of the circuit
2nd fan is for A/C system. DON'T give advice if you don't know what you're talking about. Go watch youtube or something, please stay away from posting uneducated guesses.wednesdayslatest wrote:any fuse will blow from age

Ideally, I would of said to keep the original rad fan hooked up as originally controlled, and hook up the A/C fan to your switch as a secondary/additional coolerwednesdayslatest wrote:so since i dont use my ac system can take out the ad fan for weight? or can i still use it for something?
