Headlight is very dim on 29 Model A Roadster Pickup

[dtcme99]

My 29 Model A Roadster Pickup was frame off build by my Father in law. It was part of my wife's inheritance and I've been working on it for a year, or I should say learning about Model A's for a year. I recently completed overhauling the brakes.


My issue now is the headlight brightness. The drivers side lamp works fine. The passenger side is very dim. I replaced the lamp socket and used a new bulb. No matter what I do, nothing gets better. Is there a chance the headlight wiring maybe defective or wired in series instead of parallel?


I'm still learning about the positive ground system, so any help would be much appreciated.


My 1970 Olds Cutlass 442 is easy for me, the 29 gives my headaches.


Thanks,
