12V Regulator with 6v Battery?

[Bankston92]

Hello all!

My father and I recently purchased a 1929 Model A Pickup.

Needless to say it needs some TLC.

I know this may seem like a crazy question but we are having problems getting the truck started.

I noticed we have a 12v voltage regulator but the truck isn't converted to a 12v system from what I can tell. We still use a 6v battery.

We have timed the distributor, I have checked voltage to read 6.6v and then after the condenser it reads 3.3v but we aren't getting spark.

Could the 12v voltage regulator be causing issues with the ignition electrical?

Thanks for your time! Looking forward to learning and getting this truck up n running.
