I am fighting a nagging problem of the headlights randomly going out and back on. Need a little help finding the issue. I will try to go through what I've done so far.
It started 2 years ago when the ammeter smoked its self. I had a restoration shop install a new dash and engine harness. This included a full restoration of the gauges, dash panel and a new head light switch. We eliminated the ammeter and replaced with a volt meter too. After this everything else is working fine, except this issue with the head lights. They seem to go out more when the high beams are on, but will go out both ways.
I don't drive the car much at night so I have been slow to get this fixed. This winter I have been working on it and replaced the front lighting harness and dimmer switch. I also made a bare metal ground area for the front harness ground wires. I thought that would fix it because I found some corrosion in the old harness. But it is still there. Since it is winter my testing is with the car not running ad just sitting in the garage. No other lights are effected, not dash or rear. Only headlights and high beam light on the dash if on high.
Testing today I was able to determine that when the lights go out, there is no power to the center L2-16LGN to the dimmer switch. That traces back to the top wire connected to the headlamp switch. Could it be a bad switch? All other lights controlled by that switch work fine. Also what would cause it to be random? Moving the wires with the lights on does not cause them to go out so I don't think it is a connection.
I am scratching my head. Thanks for any help you can give.
