[ He still needs to check his current draw and charging capacity
I installed one large aftermarket electric fan on a drag only car years ago and found that it would draw 70+ amps on startup initially To much amp draw can melt overloaded, to small, wires real quickly
That is why the load for these should never be off the alternator stud. Worse on older cars with inductive ammeters and failure prone bulkhead connectors. Alternator should be wired with protection direct to the battery or a buss connector. All loads should be off that point and correctly set up with relays and fuses.
