Turn Signal & Headlight Problem
 

I have a '70 that is having some light issues.

The turn signals don't work completely. You can see the light go in and out but it's a very small difference in light output. The headlights are also unequal, the passenger is a lot brighter and the driver is dim. Same goes for the other lights on the grill.

The side markers light up, but do the same blinking problem.

Would there be a benefit to just replacing all the fuses in the box or is this a problem in the harness by the headlights?

What will that do with respect to the headlights? Just curious. Still learning, first truck.

We cleaned the connectors to the headlight with dielectric. When we 'wiggle' the connector it goes from bright to dim.

Grounds make a difference with everything. The cab and radiator core support sit on rubber bushings so they will not ground correctly without ground straps. That is also why you need a ground strap from the engine to the frame. The engine and transmission mounts are rubber cushions that isolate them from the frame....

If you are talking about dielectric grease it is not a cleaner. If you mean contact cleaner you still have to clean the mating contacts with a small flat file or fine sandpaper to get any corrosion off.
