Ok being some what mechanical incline. I bought a 48 early 48 front mount distributor. The person or persons have started a 12v conversion. And several parts were stolen or just gone. I have the alternator and distributor base. Bought cap and 12v coil, now rewiring oh I was told the coil does not need the resistor/resistors in all diagrams I have seen. Any way question is the 50v 1amp diode in alternator line # 1or the option of a 5watt light, why would the light work? Is the light going to stop the feed back of voltage thru the alternator and why would it work. Not an electrician by far.
