What is the fuse on the battery for

Sounds like you cooked the main fuse going from the battery to the fuse box. Or something happened to one of the battery cables.
There should be a 75 or 100 amp fuse that powers the main fuse box.

You most likely have a short somewhere in the electrical system. Have a mechanic do a test on the electrical system.

It will be a 40 - 80 amp fuse, follow the possitive cable to the fuse box

Check the fuses, it will be a 40amp or 60amp, they are most likely under the hood in the fuse box, follow the possitive battery cable to the elecrtical box, replace blown fuse.

There is fuse called the max fuse. It is located real close to the battery inline with the possitive cable. Replace fuse and should be fine.

Under the hood

To the right

Black fuse box

pop the fuse box off (no tool needed, but screwdriver helps)

Small metal post to the right.

That is your + possitive (red wire)

Connect the black wire (-) FIRST, to a medal part of the engine that does not move when is running

now connect your possitive.

Make sure the cable does not go in the path of any moving parts on the motor.

connect the other end of the black wire to the negative (-) of the other car BEFORE connecting the possitive(+/red) wire.

Now with the other engine running wait a minute, now try starting your car.

undo the possitive battery cable jack car up in front place jack stands under the A arms for support unbolt starter from transmission & all wires get new starter & replace all wires on new new starter put starter back in bolt it down & make sure all bolts are tight & reconnect battery & it sure start

first check if battery is good and if your not leaving any thing on and check your battery terminals to be clean and tightly screwed to the battery. then turn on your vehicle and dissconect the possitive cable on ur battery. if the car turns off, youll need to replace your alternator

The fuse is the main fuse to the vehicles power supply just the same as removing the battery cable . you have a drain in your electrical system , use a test light , remove the possitive cable from the battery and hook one end to the battery and the other to the cable remove fuses till the light goes off ( make sure all doors are closed and switches turned off) that is your drain source . do no remove the 50 amp fuse in this test .

first off you should have installed an inline fuse block that fuse will pop first an inline fuse is cheap go to a wall=mart it will run you around 10.00 that gets mounted under your hood cut your power cable in half the one part of the cable should be cut 12 inches that will tie into your possitive terminal on your battery after that is all tightened to your battery you will strip about an inch of coating offf of your power wire tie that into the end of your fuse block make sure it is tight than do the same to the other side just measure from there to your mounting spot for your amplifier and tie your power cable into your amplifier use 8 gauge power and ground cable... your problem with your amp is that you burned up a couple capasitors or even a resistor i just fixed an amp that both fuses were smoked just tear your amp apart look under the control board you will see were a sauder joint is cracked those capasitors and resisters are very cheap there made out of ceramic i just got done repairing my friends amp works like a new one.. good luck if you have problems or w you get it fixed email me..
