I have 6 volt original positive ground voltage regulator that I rewired to negative ground. Does it change how I wire the regular and if so how? Thanks

I don’t know about the regulator but I am curious as to why you changed from 6 volt positive ground to 6 volt negative ground

I ordered the wrong pertronix lol

The regulator is still wired the same. The difference (if there is one) between the neg. and pos. grnd. regulators is that the dis-similar metals on the regulator contacts are reversed. In theory, the regulator will have a reduced life span, This applies only to the better quality regulators, cheap ones likely do not have dis-similar metals.
