Fenix's Goblin #461 - 2010 Base Auto

Also confirm good grounds on this circuit. If they all ground to the same "bad" point, they can back feed through the other bulbs and back through the entire system finding a path to ground.

This overly bright headlight is harder to explain since it should only get as bright as directly to 12v at the battery. But if it has drivers/transformers inside the light I guess that might do weird things if it is seeing low voltage. Or it's

Back with some report.

Confirmed the driver side bulb was blown, replaced and its brightness and usage has gone back to normal.

Reports are done on a 20 dollar multimeter

Your meter is set to Volts DC and 20 volts (or whatever setting is closest to a 20 volt range)?

The symbol for Volts DC is typically the 'V' with a straight line or lines with it.

This is the setting on most all inexpensive meters. These photos are just an example, your meter my look different.

Where are you putting the black lead on the meter for a ground reference? The steady voltage readings make some sense, but the fluctuating voltages on the white wires do not. Can you disconnect the white wires and check these again on the car side wiring and the wire on the headlights. Don't disconnect any of the other wires.

sorry for the long gap. the electrical issues have been sorted. also now legal to drive. yay.

Great news! Glad to hear the electrical has been sorted out and your running again. Montana plates too, working around the local/state issues with selective vehicle registration. Did you get the insurance thing worked out?
