The Roadster Factory lists the same part number for the TR-3 generator and the TR-4 generator. However, the TR-3 was originally positive ground, while the TR-4 was negative ground. <span>Are these new generators set for positive or negative ground, or are they designed to handle either? </span>I changed the polarity of my car when I restored it years ago, so it is now negative ground.</div><div dir="ltr"><br></div><div dir="ltr">My question is, do I need to polarize this new generator? If it is set for a negative ground, I'm afraid I might switch it to positive ground if I do that "flick" thing. The instructions Albert sent me said to run a wire from the battery terminal which feeds the solenoid (positive in my case), then flick it against the field coil terminal of the generator. OK, if I need to do this, which is the field coil terminal, the one on the side of the generator, or the large one on the end?</div><div dir="ltr"><br></div><div dir="ltr">I don't want to do anything that will burn out my new generator or voltage regulator. Thanks for any help you can give me.</div><div dir="ltr"><br></div><div dir="ltr">Jack Wheeler<br></div></div></div></div></div></div>
