make sure your grounds are good and check the tightness of your belts, IIRC you should have only about 1/4 in of slack in the belts

is your battery running down while your driving to where you have to boost it off to crank? or are your lights just flickering?

Put a multimeter on your battery while your truck is running and verify 13.5-14.5 volts are present and 12.6 after shutdown. This is the easiest way to check alternators and alternator circuits.

no they just dim and bright while driving.the battery jus gets drained

Had the same problem with my Superduty. Lights would go dim and voltage dropped to 8 volts on the gauge. I had replaced both batteries and alternator 6 months prior. Exchanged the alternator (Napa warranty), problem solved. I think the voltage regulator was bad.

my first thought is also to check the battery voltage while running with a multimeter. second thing, grounds, and go from there.

Awwww, thats too bad. I dont like forums either, thats why I create accounts and post on them. If you have a hard time accepting help, why'de you ask? Hope all goes well (or better)with your truck and you get a new alternator to get it back on the road.
