Flickering lights!

7998 Views 7 Replies 6 Participants Last post by  Bow
I have an 02 Frontier crew cab, 3.3L which I bought a month or so ago. I have a problem that the headlights (& the interior dome when illuminated) flicker constantly and annoyingly when the engine is running. The battery appears fine - no starting problems - and the motor is running OK. Any thoughts on what could be the root cause? Alternator, Grounding, Voltage regulator (does the Frontier have a seperate voltage regulator or is it part of the alternator).

Appreciate any insight that anyone can bring to this problem!

Loose Ground

Look at all the main grounding points that come off the battery.
Check that they are clean and tight.
Check the Battery Ground terminal that it is clean and tight.
