Ok I finally got to take readings with my multimeter. With the truck turned off it is showing 12.1v at the battery. With the truck running it shows 14.3v, that is with no extra load and with everything turned on still 14.3. With the battery showing 12.1v the truck will not turn over or should I say it turns over too slow to start. The cables from the battery are good, I replaced the negative cable 2 years ago. I am leaning towards the cable going to the starter or the starter itself. What do you guys think. One other thing I measured ac current at the battery with the truck running, I got flashing reading of 0.0 and 8.9 could this have something to do with it? I think it does but can't remember what.
Thanks for reading the paragraph and the help

I know it's a dc system, but on another forum I visit the electrical expert always says check ac at the battery. I can't remeber why, will go back and check. I think it has to do with a short. I will check the wires to the starter. I am thinking that or the starter itself. I will let you know what I find tomorrow.

the only way u going to get AC in electrical system its if one of the diodes in alternator goes bad but that can damage electrical components or just dont work cause they r make to work on DC.
