Re: Dim Headlight
My left side lights were dim also. First I checked the voltage at the inside ( two post) headlight with a voltmeter, set the meter to DC volts and connecting one lead to the negative - post of the battery and the other to one side of the headlight (on head light itself, not plug). Meter read battery voltage, 12+ volts approx. Next I connected meter to the other terminal on the same lamp, meter read battery voltage. This told me headlight was good and getting voltage but was not being grounded. I found a broken ground wire which connected both lamps on that side to ground. Hope the helps. Ground was laid under one of the voltage regulator mounting screws. My not be correct but that was where it was landed on my 70.
