Hey Gents.. so the 6 volt battery was swapped 3 times. The gauge pick it up fine. Changed the starter solenoid, changed the regulator, and had the alternator checked. There is zero anything when trying to turn over. Any help or guidance is appreciated. There was a Mechanic that removed the heater. Anything here possibly? Thank you. After this, I'll need to tackle the massive white blowby front and back.
