Got curious as to the amp draw for Winston Cup cars. Found some data which might be interest to a couple of folks. The absolute max that a team will allow is 100 amps. There is a long long article on this and the alternators used by the WC teams if anyone wants I'll link ya to it.

TYPICAL SHORT TRACK AMP DRAW (HIGH-AMP TRACKS)
Ignition system
10 amps

Brake fans (as many as ten fans @ 4 amps each)
40 amps

Rear end cooler fans (2 fans @ 4 amps each)
8 amps

Driver air conditioning system
30 amps

TOTAL POTENTIAL SHORT TRACK DRAW
88 amps



TYPICAL LONG TRACK AMP DRAW (LOW-AMP TRACKS)
Ignition system
10 amps

Brake fans (none used)
0 amps

Rear end cooler fans (none used)
0 amps

Radiator fan (electric)
22 amps

Driver air conditioning system
30 amps

TOTAL POTENTIAL LONG TRACK DRAW
62 amps



INDIVIDUAL COMPONENT AMP DRAW
Ignition system (w/Crane box or MSD red box)
10 amps

Ignition system w/new MSD 6430 box
14 amps

3-inch Brake fans
3-4 amps each

4-inch Brake fans
6 amps each

Rear end cooler fans (3-inch)
4 amps each

Radiator electric fan (when used on short tracks)
6-22 amps each
(depends on fan size and quantity)

Driver air conditioning system
30-33 amps

Windshield wipers
4 amps

Defroster
8 amps

Dual battery solenoid (where used)
4-6 amps
 
All of the cameras and the radios are required to have their own isolated power source. None of these draw on the primary electrical system of the car. One would guess this to be some type of rechargeable battery.
 
Remember the battery that "blew up" in Robby Gordon's car at the Glen(?) a couple years ago?

That was 2001. Robby clearly had the best car that day, he was pretty angry after that, I would have been too.
