The model 630 I'm working on, which sat for 30 years, is a 1955 2nd series, not a 56 as was told to me (I doublechecked the serial number). I'm now looking at the electrical side of things. It is a POSITIVE ground 12 volt system. My research shows that in 1955, 12v pos ground was an option, with 6v pos ground being the standard offering. Also, this being a former firetruck, it has a Leece-Neville 100 amp alternator, with a large control box or regulator, and a large rectifier. I plan to eliminate that system. I unhooked all leads from the alternator today. Would there be any harm in trying to see if the engine will start with the alternator leads removed, but leaving all the other components and wiring in place for now?
