Can an alternator fuse blow?
Your alternator will typically stop working when the fuse for it has blown. The fuse might blow because of old age, and it might blow because of a power surge within your car. Either way, you’re going to have no choice to replace a fuse when you have an alternator fuse blown.
Should I put a fuse between alternator and battery?
Fuses are installed to protect wires from an overload, meaning that the draw (amps) from the load (appliance) exceeds the capacity of the wire (the size or gauge). Under this premise, the only way an alternator needs a fuse is if either the battery or the alternator itself experiences a dead short.
Is the 120 amp fuse for the alternator PAL?
It must’ve been brief, because I didn’t see/hear/feel a spark. So the 120 amp fuse for the alternator is a PAL type fuse, and it is a bit of a PIA to remove. I’m a mechanic, so it wasn’t very difficult for me, just time consuming. However if you were an average Joe who somehow made the same mistake, you’d almost certainly be going to a shop.
What to do if your alternator blows fuse?
From there, I had to push in all the tabs on the side of the fuse box to separate it so I could gain access to the screws holding the fuse blades to the terminals themselves. Once in half, I had to fish my a socket past the mess of wires inside the box, and unscrew both terminals.
What should the voltage be on a Toyota alternator?
Turn the key, and I get nothing, not even a click. I check the battery voltage, read 13.1 volts, so I am fine there. I have lights, radio, door chime, etc. Next I check the alternator to make sure it’s hooked up correctly, and it is. I’m getting frustrated at this point, but decide to check the fuses.
Why does my Alt fuse keep blowing out?
I covered the bare metal under it with rubber to ensure that I wouldn’t ground, then screwed a nut and washer ON TOP of the wire, instead of the normal setup which is nut, wire, nut+washer (broken post).
