Your ground or power can be hooked up wrong....or the fuses might not be big enough...mine was having the same problem!
the power suppy diode are probably shorted.
In how many amps of current before blowing out. 2 amp 5 amp 10 amp 15 amp etc.
The 50 ampere engine fuses is blowing because more than 50 amperes of electricity is passing through it.
Find out why the fuse is blowing. You have a short or the circuit is overloaded.
Not a good thing to do! If you are blowing 10 amp fuses, you have a problem with that circuit. Putting a 30 amp fuse in its place can do more damage.
There is an electrical short to ground in the fan switch or in the blower motor itself.
could be that the regulator in the alternate is failing and causing power surges in the electronics and the fuses are blowing to prevent damage to the device and vehicles wiring.
There is a short somewhere.
for fuse to keep blowing, there is a short in the eletrical system somewhere. check the a/c switch and the a/c clutch
It is very common for the starter to be the cause of that fuse blowing.
Wrong amp of fuse
If your wipers keep blowing the fuses on your 1998 Nissan Altima, it could be a short or the wrong fuse being used. You may have a short in the wiring or the wiper switch, a bad ground wire, or loose wiring.
