To fuse or not to fuse HO alt?

[West1 10+ year member]

This weekend I will be installing a mechman 270 in my frontier. I read a lot of mixed replies from these type of topics.

I will be running 1 fsd 2600 and 1 fsd 125.4

XS power battery under the hood (one battery total).

If so, 300ANL fuse good? or don't bother??

up to you, i leave it unfused to avoid voltage drop but with a 300a fuse (unless you're pulling nearly 300a) you wont notice a difference

no one can argue against it being safer fused though, so if you're concerned id fuse it so you can have that confidence

add a ground to the alternator directly if you can

If there is any chance of the power wire getting cut fuse it.. I'd hate to lose the entire car over a 1/10th of voltage drop.
