2: If that doesn't work, get a $10.00 DMM from wal-mart or an autoparts store to check the battery voltage. It should read from 12.4-12.8 Volts, with nothing pulling on the system. If it is below that incrimental range, it could be one of two things.
- Battery is just .... well dead, and will need replaced.
- Battery is weak but not dead, and just needs charging. If this is the case, it is more than likely your altenantor..... read on
3. To check to see if the alt. is not working, hook the battery back up to the terminals and let the truck run for a while. Then apply the DMM to the battery while the truck is still running. It should read ~14.2 - 14.8 (average is 14.4). If it is well below those numbers, your alternator is probably no good.
Hope this helps some.
