A/c fuse melted in fuse box can that be fixed?

Question translated into written English.

The fact you have melted wires is a big concern. If the wires were melted, that means the components connected to them as also melted, even though they should have been protected by the fuse. The multi-pin plugs that connect to the fuse box are probably melted as well.

Diodes are a one way valve for electricity, it it had diodes, it needs diodes.

Next to the alternator and battery you'll find an essential, though often overlooked component; the diode. Diodes allow current to flow in only one direction. ... Functioning as a gatekeeper for back feed into the circuit, the diode protects essential elements of the car from current spikes.Aug 25, 2020

You need a good auto-electrician, or a new vehicle!

Hot wire not protected by a fuse and a direct short to earth , the fuse box and melted cables have to be replaced .

first off what vehicle are you talking about and second if melting and or over heating the relay need to check why such as to much heat for where relay is --a bad circuit connection causing high draw --fuel pump excessive draw --bad or grounding circuit corrosion or faulty connections

Maybe the fuse box is bad , corrosion inside . Take the box apart if you can an look inside . check all the connections for corrosion also.

Replace the wires as far back as necessary. They could have melted all the way back to the ECM. Probably other wires to fix in this case.

check you alternator diode or you change the alternator complete

Hello stanford8
A new or used fuse block is the recommended way to go. But in a
pinch, remove the fuse box mounting screws and pull it back to make
sure no other wires got melted or damaged. Cut the power out a/c wire
from the box. I should have said this first, pick up an inline fuse+holder
with the correct amp rating. connect one end to the 12v pwr in connection to the fuse block and the other end to the a/c power out wire
This will bypass the fuse block for the a/c only. The fuse holders are
available at any parts store. Also it would be wise to locate and repair
the cause of the meltdown first, if you havn't already done so.
Hope this helps.

You need to be a bit more specific as to what is wrong with the fuse box. Melted? not there at all?

i do not know what you are talking about when you say "make the water work", but no, you cannot bypass a fuse. Especially when the problem is bad enough to cause a fuse to melt. You are going to have to have someone find the short that is causing the problem and fix it. Fuses are for your and your car's safety. They help prevent fires, as you see the heat that amperage generates' effect on the fuse.

Hope this helps with your question,
