So my batteries have died for the 2nd time in 3 months. i just bought new batteries a few weeks ago and just slowly ive been getting less power out of them. my alternator looks pretty new im not sure if thats the problem ive cleaned the connecters. any other possible ideas

 

get the alt checked at yer local parts place. if its good you voltage regulator is probably bad and frying the batteries. that is if your truck has one im not sure.

 

X2 on the alternator! You could also check it yourself with a multi meter

 

U can't really confirm if it's capable of putting out full amperage with just a multimeter.

 

alternator is bad. picking one up tomorrow
