wiring extra battery

ok i just bought a new batt and will hopefully get it by next weekend. Before I install it, I have heard tht it will put too much of a strain on my alt. and fry it. Is this true? How do I prevent it.

im at this level also.

exept i am putting 2 smaller batterys in my rear storage compartments.

big 3 is getting its alt - to bat + wire fuzed and with a disconect key ( kill switch )

that way - the battery will not energize the alternator when the car is not running, so I can just basicly turn that wire off. - I have my regular battery for the car on a kill switch too,

as my stupid corvette seems to have a "small" electrical drain somewhere I cant find yet.

I was also thinking,

each smaller battery in the storage areas will get a 60amp fuze about 12" away from each battery on the + cables and am concidering adding a kill switch to isolate the rear batterys if nessary, as - once my box is in the car - it will cover the batterys and axess to them

and it might be nice to be able to turn them off if something goes crazy wrong.

never heard of needing a kill switch to put on the wire from your alt to your battery positive
