Flickering or pulstating Headlights
I've mentioned ripple a couple of times.
Basically its the left over alternating current waves when the electicity was converted to DC.
If we had an oscilliscope we could see the voltage over time.
Its usually very small compared to the voltage, so we don't see it on the meters. Something like 0.1 Volt
If a diode is bad, then that portion is not rectified and then it looks like we're seeing a bad ripple.
