Fuse for alternator to battery isolator question

Post by BabyGodzillaGTi-R »

Hey guys quick question as i'm quite clueless about electrics.

Say if i have an 80 amp factory alternator. Is it really necessary or an option to fit a fuse inbetween the alternator and your typical 3 post Warn Isolator (mine looks ancient, squarish and goldish with lots of heat sinks).
If so what fuse size do i need?
I realise the mech fitted a 30amp fuse recently.
Is that adequate or plain unnecessary.
Or should i just run direct?
Btw anyone have an idea how much amps could my Warn Isolator take? Taking a wild guss 90amps?

2nd point.
Is it a good idea besides running a battery isolator setup, i run a direct wire connecting battery a and battery b and inbetween this line an electric key/ cut off swith so that in a worse case scenario where say a flatten battery a from winching i can connect both battery a and b in an emergency.
Good or bad idea?

Thanks in advance guys.
Cheers.
My RIG sucks big time.
