[my240]

I went down and took the neg off alt bracket and filed it and wire for good connection. Now got 12.41. Still no start. Put charger on battery at 40a for a few minutes still no start. Put it on 225a boost and truck fired right up. Load meter on battery didn't show bad. It's a brand new battery. I'm going to let 2a trickle charge all nite. I don't feel it could be as simple as a bigger battery? I don't really know about this j stud on firewall to check voltage. Didn't see anything to put meter on. Something else goofy,,the resistor for the fan blower i changed and the fan would come on high when you turned key. With the 225 boost connected the blower came on low as it always did?? Do i need it connected and running to start truck?
Thanks again
