Hello, Truck is a 2000 chevy 4x4 with a 4.8 in it.
All of a sudden it wouldnt start. charged battery and it would start but just
doesnt sound strong.
Volt gauge stays about the next mark over 14. probably just battery???
Oh yeah its came new with truck..

 

Take a volt meter to the actual output of the alternator, and if you have one take an amp meter to it also. Check for any corrision or loose connectors around the battery and alternator. If all that checks good then you probably have a bad battery. The simplest way is to take it to someplace that does free battery checking. If possible take the vehicle there, they can usually check the charging system also.

 

thanks, Took it somewhere and it was the battery.
Alt. was charging fine..
