Battery problems
Well I just got home from my honeymoon this morning. This afternoon I went to go start my truck up and the batterys were almost dead. It made about three cranks and then it wouldnt crank anymore. I didnt have anything on while I was gone. I had my buddy jump start it and then it was fine. Then tonight I was driving and the battery light started comming on and then flickering when the RPMs got higher. I hate electrical systems and I thinks the battery light is for the charging system but I have no idea where to start. Any help??

Alternator is toast, go ahead and replace both batts(unless they are pretty new) also. A failing alternator can burn up cells in batts. And Yes the batt light means the alternator is not putting out.

Bad batteries won't take a charge. Are they the original units? If so, they are overdue. Get new ones then test the alternator with a multimeter by probing the baterry terminals, both. The alternater should be putting out at least 13.5 volts. If not, pull that out and take to parts store and have it tested.

my buddy is kinda wondering if its the alternator or not because he had one go out on is PSD and it went out all at once. Mine the volt meter on the dash reads right and everything. Just the batt light stays on and when the rpms get to about 2g it starts to flicker then at about 2400 it will turn off. once you let off the fuel it will come back on. Like I said I know nothing about electrical just following up on his question.

Like Tenn01 says above.. get a volt meter and put it on the batteries and at idle, wait for about a minute while your GPR kicks off and you should have in neighborhood of 13.5 Volts or alittle higher... If not, your alternator is toast..
