Electrical Problem

[thankins93]

i need help. The battery and alternator are good, but for some reason when i drive my headlighs flicker and the running lights are real dim in the back. i checked all the grounds that i know of and when the interior light is on and you press the horn the light gets really dim. What could be causing this problem? any help is appricated.


It is a 82 burb, 350 3/4 ton 4 wheel drive. I got pulled over lastnight because hte cop didnt think i had my lights on and id like to get it fixed.

i would look at the switch. check and see if there is a voltage drop across the headlight switch. could also be in the ignition switch but that would be rare.
