I finshed a motor swap pretty recently, and discovered the other day that all my left side lights are dimmer than my right side. (to include my headlight, my parking light, and my left fender turning light.) I tried swapping bulbs, but that isn't the problem. I am not too fond of electrical problems so I came here. Maybe a bad ground? fuse? Any help would be useful.

 

id guess a bad ground, there is probable a wire thats got a shotty connection with metal.

 

Yah that is what I figured it could be. Just wasn't sure how to tell, or how to find out what wire and where.

 

I would say ground also, sounded similar to a problem that I had on my 82 cutlass. The wire had rotted out, the connection to the body looked good, when I started tugging wires the wire just pulled apart.
