Alternator will not charge battery. Alter is good, just had it checked. And have a new battery in the truck. Battery light on dash is on. The batter cables where put backwards. And now the alternator will not charge battery. Need to know what is going on before I start ripping wires out of my truck..

I have checked all the small fuses. Put new Alt. And battery in truck. Have tested Neg lead Alternator and get a reading. Test pos. to lead to alt and get almost no reading. These tese where done with no Battery in the truck. Trying to see if I may have a break in the line. Need help to get this truck back running right.
