Electrical problem
1969 Plymouth Roadrunner V8 Two Wheel Drive Automatic

I have a 69 R/R 440 with approx. 500hp not a race car just a weekend street car. I have new electrical wiring in the engine compartment. I have no problem running my car during the day, but once I need to turn on the lights the vehicle shuts down. The vehicle is not able to hold the load of the lights. I purchased a new battery optium with pleanty of juice, should I be looking at the alternator possibly. Any advise will be greatly appreciated.

Thank You
R. Mata

If you still have the 1969 alternator on it, you can do a full field test while you have a meter hooked to the battery and the lights on.

That would give you a good idea if the alternator is too weak.

Or if you still have a points style regulator, it could need to be cleaned and adjusted.
