Doh!

So would it be a good idea to change the fuse or is it not needed?

Another area it does good, typically amps, sometimes HID's, fans, etc dont get tapped in to the stock power wiring, generally they get power wires run seperately, so the current doesnt even go through that fuse.

I have never seen an accessory wired to the alternator post. That's the only connection point that's 'behind' the 75/100A fuse. Wired anywhere else, the accessory pulls through that fuse.

Longfellow: Change the fuse if and only if you've upgraded the "big three" - alt to batt, batt to gnd, eng block to gnd. Otherwise, you're setting yourself up for a fire.

^^Yeah, I've noticed that.
And Anybody know where I can find a full A/C vent assembly for a '93 Hardbody?
My '89 vents slides in but doesn't line up all the way and I want this thing at it's absolute best.

Generally i've usually got a 8, or 4GA wire from alternator post to battery anyway.

Stereo, direct 4, or dual 4 to battery going through fuse or circuit breaker.

Of course other than my nissan, everything i've had for the past 10 yrs or so has been 100+A, and usually 140A, current one in my build is 155A...
