What is normal voltage drop when you turn on the lights? I’m just going off the volt meter, but I start at about 14.2 driving around, when I pull on even the first notch of the light switch I’ll drop to less than 13. Is it a ground issue? I understand that this a rather common. Thanks. Dave

Thanks everyone. I understand the age of the vehicle and that this is "normal". To be clear that the biggest drop to about 13 volts happens with just the parking lights on, not the headlights. Then with the headlights on, to less than 13. I have replaced the fuse box with the newer style. I don't know what I would have at night, in the rain with fog lights on. Is it a ground issue?
