ok the loud sound I was having has been discovered, it sounded like the starter drive gear not coming off the starter ring gear, I got the truck started and got under there I had my son turn it off at first I didn't see anything but hear the loud sound we tired it again and I saw that after it started to turn off the starter gear popped out and partly engaged the ring gear I never could see it at first but that was it, I came to find out that it was doing that because of the wire from the alternator to the switch was still hot after I turned it off and it was causing the starter to reengage I figured this out because when I disconnected the wires from the alt it stopped doing it problem solved I had a connector that I used on an old 57 buick that I rat rodded, it connects to the plug that goes into the alternator, it has a diode in it that keeps the juice running the right way and not kicking back, i found it put it on and bam!no more noise and everything was charging like tom petty sings even the losers get lucky sometimes!
