Yea i'm checking it at the battery when it's running you can take the cable off and it will keep running as long as you rev it up a little but at idle it will run for a min. and die but i do have the fans running and has a msd to.........
Now the truth comes out. MSD does take some current but not too much for a stock charging system. Now your fan(s) are a different story. They may be using up to 30 amps. The stock alternator might not have much more output than that. @Mattax
