This just started.... or at least I just noticed it. With the headlights on dim and engine warmed up and idling, the brightness cycles from normal to slightly dim. Cycle time is around a second. When I rev the engine slightly, they return to normal steady brightness.
When running with or without lights, the ammeter is just right of center, slightly charging, in the normal position.
I don't suspect a connection -- within the last 2 months, I removed and cleaned all the battery connections, including regulator and other parts when I was fixing a grounding issue.
Battery cranks start just fine. No other indications of failing battery.
Thanks folks,

Do you have a tachometer? Does the RPM oscillate?
RPM is steady. Oscillating lights happens at slow idle. If I increase idle speed just a little with accelerator, lights are steady.
