OK guys , I need some info. I would like to replace the generator with a 3 wire alternator 10-SI and 12-SI on my 1959 Buick Le Sabre. I bought a alternator braket from a 1964 Buick Riviera . So is there a 3 wire alternator that will fit a Riviera? Thanks
I don't know the answer to your question. But, a heads up (if you don't already know) , switching to an alternator will disable the accelerator start on a '59 Buick. If, you haven't already, you'll have to rewire it with a push button starter switch. Good Luck and Welcome to V8Buick
You probably already know, but they did come with a 10DN externally regulated alternator, so a 10SI should bolt right in. But as far as brackets go, you'll need the aluminum lower bracket, the flat steel upper bracket and two long head bolts that go through the lower bracket. Keep us posted, and take pics -After changing my regulator like three times, Ive often thought about changing over to a 10SI, just haven't gotten around to it.
Don't bother with 10Si just get one of those 100Amp 12Si they are about 100 bucks on evilbay. I installed 140Amp 12Si and upgraded charge cable to bigger wire. works like a charm. 3 wire unit ofc, 1 wire is mistake. Just an example: http://www.ebay.com/itm/New-Powerma...Parts_Accessories&hash=item3ceb5a2e0c&vxp=mtr Peace, Kacper.
The alt. bracket from a '64 Riv. won't work. It will be longer in spots as the 425 has a taller deck height than the 364. The aluminum one Rhett is talking about should work. You'll have to finagle the flat bracket to work. The Riv. bracket requires a 1/4" longer bolt plus the 1/4"longer bolt n the front of the timing case cover. The aluminum bracket requires two 1/2" longer bolts. This stuff is getting harder to come by so the $$$ can get to be a sore spot. There's plenty of info to keep your start pedal feature by doing a search here or other places like teambuick.com or the BCA site. Tom T.
I can build you an alternator,check my vendor post for examples.But first off,why the conversion? Nothing wrong with the generator system on a stock application.
Of course Tom is right. I should've said; the starter circuit would require rewiring. Mine works very well, after a good rebuild of the generator along with a new regulator. I just had mine rebuilt about 15 months ago. Before that, the generator had given 10 years of good service after being parked for 23 years. Something I learned is; A new regulator should be installed along with a generator rebuild or generator replacement...
