Mechman 370. ( DO I FUSE MY TWO BATTERIES WITH A 400 AMP FUSE)?


Recommended Posts

The battery would only blow the fuse if the short was between the fuse and the alt. Chances are that the cable between the fuse and the battery would short because it is longer. In this case, the battery would be unprotected and continue to provide current to the short. The alternator would supply current to the short too because it is unable to blow the fuse. If you are worried about your alternator cable shorting out then you have to member that it is also a battery cable and fuses are needed at the alt and the battery.

I disagree with the fuse location. Even between the alt and the battery, the fuse should be closest to the battery. No fuse needed close to the alt in my opinion.

 

to each his own. We all have our own risks we're willing to take. I don't fuse my alt to battery at all. It's such a short run that the ampacity at that length will never be met by the max discharge of the battery or alt.
