How important is it, where can I get it.. One more question, what is the difference if I ran my new 4 guage power wire to the starter solenoid instead of the positive side of the battery.

Never heard of a mega fuse,but if you want to fuse the alt go to your local car audio store and get a ANL style fuse/holder.150-300 amp fusewill work.As of running the 4ga to the solenoid instead of the batt there will be no difference

It's not mandatory, but it is a good idea.

you want a 120amp "in-line" fuse.
they use them in car stereo install with big amps.
I got mine with sealed holder case at CircuitCity.

wouldn't the 120 trip with a 135 amp alternator at peak power output? or am i thinking bass ackwards

tmajikman

do you think a 120 amp fuse will be good enough with a 200 amp alt.

I ran mine to the solenoid. It's fine. I know they tell you not to, but it doesn't seem to hurt anything.

Thanks for the info fellas, I guess I will find a big fuse to complete my install, it is nice to finally have my battery charging normally.

Alternators only put out as much as they need to.

I run a 120 amp fuse on my 200amp alternator. Car never draws more than about 70-100amps
with everything on.

I got 200 amp alternator cause it puts out 100amps at idle.
vs. 35amps at idle for stock alternator.

U/D pullies suck for charging problems too, dumping mine to go back to
stock size crank pulley too.

Thanks for the heads up, I will look into a 120 amp fuse now that I know this.

okay, i gotcha... it's not what it's capable of, it's what it's actually drawing... thanks
