Hi everyone, I've got a 1st series '49 that I bought and have never got it to hear it run. I got it from a local school auto shop and the instructor told me that he thought it just needed a new coil. They put in new spark plugs, changed the oil and got the engine to turn over by hand. It still has the 6 volt system but the wireing looks pretty bad so I think it needs to be replaced. I want to upgrade the gauges so I'll eventually be converting to a 12 volt system. My question is now that I have gotten a new 6 volt coil can I crank the engine with a 12 volt battery without causing any harm? Like I said I'm going to go to 12 volt so I hate to invest in a 6 volt battery just to hear this thing run, I've got a lot of work to do before I get roadworthy. Thanks for all your help and expertise.
