The current statements in post 15 don't appear to be based on fact but on ratings. What the system draws and what can be delivered aren't the same.
My point is maybe the system is marginal at idle but it may not be an issue since it doesn't idle that much.

Not sure exactly what you are alluding to and no need to be rude... But my issue is I do not have a large stereo or subs or anything that draws alot of power except the lights and when I'm stopped, idling at night with them on (say at a stop light), my headlights are in " seizure mode" they dim to the point of flashing on/off rapidly... I stated my voltages at idle and approximately 1300 rpms on the engine... I'm personally not sure where else to look... I have enough amperage and voltage to keep the truck running and the battery charged so... *shrugs* "No solution, looking for a problem"... My problem = flashing lights, either not enough voltage or amperage (12.4v @ approx 38A, at 800 rpms,idle) but 60A+ and roughly 13.8v past 1300 rpms on the engine.. Pretty clear to me... *thinking* I'm pretty "new" to these older trucks, and for some reason generally speaking "internet hide and seek" is not my strong point... Besides that 90% on the "information" on the internet is either porn or fake... So... I come here to find real people that have the actual knowledge from real world experience....
