Headlight Troubleshooting

[walt]

The low beam on the drivers side is out, high beam works fine. Thinking it must be the bulb, I replaced it with the same results. Checked all the wires at the Sucro relay kit that I installed a few years back and they seem OK. The yellow wire at the bulb socket does have 12V.

Suggestions what to check?

Thanks, Walt

You need to get or borrow a voltmeter, relays unless smashed or on fire "LOOK" fine, you need to track the voltage across the switch side and the power side ...............

Problem solved. The fuse looked fine but maybe some corrosion around the ends. Was getting fluctuating ohm readings. Time to clean all the contact points.
