<div class="userStyles" style=" font-family: Arial; font-size: 12pt; color: #000000;">Yes, it should work if you polarize it the way that Glen Effinger suggests.<br>
<br>
Good luck,<br>
John

<div data-setdir="false" dir="ltr">Thanks to all who responded to my question. I was corrected on the fact that Triumph switched to negative ground when the TR-4A was implemented (1965). The TR-4 was still positive ground. But, the Roadster Factory lists the same part number for the TR-4 Generator (205939/AL) and the TR-4A, so my logic is still correct. Not that it applies to me, but I wonder if there is any difference when using this generator on a TR-4 verses a TR-4A?</div>

<div dir="ltr">I just bought a new generator for my TR-3A. 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"> </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"> </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>
