I decided to add a radio and 12 volt outlet, for GPS, to my TR3. Once again, I love this forum. Thanks to previous threads, the conversion went easily. One thread suggested polarizing the generator at the "field" terminal of the regulator rather than at the generator. This was simpler than crawling under the car... good tip. I had a positive ground Pertronix module in my distributor so I've ordered the correct negative ground module. Until I receive it, I won't be able to verify success.
