=====================================================================

I know this doesn't have a limiter cause I get 5800rpm in first (if I 
want) and sometimes it's good to that rpm in 2d. But other times it just 
dies off at lower rpm's like 4200. That was when I had the electric fan 
running which takes 18amps on it's own. It can die off in first too but 
less likely.

I think I heard that the ign takes about 8-10amps to run. I do have a 
very good and new Interstate battery. I was told that alternators are 
considered good if they produce 75% of their rated amps and most are 
only putting out about 80% to begin with. It was a night race too so I 
had headlights and fan running. That's getting right up to the 35amps 
with 18 fan, 8 ign and whatever all the lights take. Should I shut off 
my 100amp boombox :-) Could discharge the battery methinks. But then 
thinking makes my head hurt.
