Pops 70 gs skylark Put new headlights in her today all four. One low beam is weak. I checked and cleaned the ground I hooked up the high beam wires to the low beam lamp and then it was at the correct brightness so I know light itself is ok. But when the correct plug is on it it's weak but the other side is ok. Any ideas......
Compare the volts getting to the low beam on the bad side vs the good side. If they're the same, a ground is your issue. If it's lower V, you need to find where that side has a voltage drop. Really the only 2 options.
Ok cool deal. I was thinking maybe a cut in the wire SOMEWERE... I was running out of daylight so I was rushing also
It's lighting up somewhat even though it's weaker, so it's getting told by the switch to turn on. Whether it's a dirty connection, almost broken wire, corroded wire, or a bad ground, it should be relatively easy to find. If you find low voltage at the bulb, start back probing until you find battery voltage in the wire. Then you'll know it's between that spot and the bulb.
