Lighting issue.

[Raycuda]

All of a sudden, my directional signals will not work with the headlights on. They work perfectly normal when the headlights are off. Everything was perfect until this week. Any hints as to where I should look?

hazards work? check hi /low foot switch. see if it's melted. Headlight look ok? watch amp gauge reaction.

sounds like a ground problem could be in the front or back lights

Always check ground connections first. Very common issue on early cars.

Hazards work, but the fronts are dim. Foot switch was replaced last year due to corrosion, but I checked it today and all is good. No amp gauge, I bypassed that and replaced it with a volt meter.

Front lighting wiring.

Rear lighting

IF you feel confident. This is not to hard. Unplug connector for the front and rear lighting. apply power to each wire to see if bright or dim. If dim check each wire for broken or corroded sockets,plugs and ground. If bright it's inside. The rear connector is in the drivers kick panel.

Hi y’all. Having same issue. What setting do I put the multi-meter on to check stuff like this?
Thanks
