Does anyone know of a source for the wires that convert the wiring harness from an externally regulated alternator to an internally regulated one? To be more specific, the externally regulated alternators have a 2 prong plug that is for the most part square looking while the internally regulated alt.'s have a 2 prong plug that is flat/rectangular looking. I am looking to convert from the square plug to a flat one without cutting and splicing, there is a plug & play conversion available.
It's pretty easy to do. You need a plug like this: http://www.painlessperformance.com/webcatalog/largeview.php?SearchField=30706&SearchAll=Classic Cars http://www.buickperformance.com/alternat.htm You can even contact Jamie. I bet he can make up a kit for you, and supply the alternator if you like. http://www.v8buick.com/showthread.php?t=89861
DeeVeeEight Quick question for ya . I am doing the same alt conversion on my 63 riv that has a 70 455 in it. I thought I re wired it correctly but when I hook up the battery the magnets in the alt are charged( u can feel the magnetic pull if u spin the alt) and the alt gets hot really quickly . Any ideas? Thanks in advance. Cliff
Cliff, I could not find the wiring diagram, but it is pretty straight forward. Take the large flat 4 prong connector that goes to the external voltage regulator and jump #1 and #4 terminals together, use a good heavy gauge wire. Cover up #2 and #3 terminals, they are no longer needed. Purchase a flat 2 prong connector for your internally regulated alternator and convert the old square 2 prong alternator connector to the new flat 2 prong alternator connector, pay attention to the polarity/color codes. Voila, you're done! Check voltage output at the battery with the engine running to make sure that the alternator is charging. You may need to rev the engine to get the voltage regulator to kick in. You should see 14+ volts at the battery if the system is charging correctly. :Smarty: I hope that helps!
Cliff, This may sound dumb so I'll apologize in advance.... Do you have a new internally regulated alternator or are you trying to convert your old one?
DeeVeeEight Sorry it took so long to reply. I was converting fromthe original externally regulated alternator to a new internally regulated 100 amp alternator. Your explanation of how to wire it up worked great! Thank you so much, I had found a different diagram for how to do this and it most definately was not correct. I am getting 14.4 volts at idle and when I turn on the 3600 cfm electric fan I am getting 13.6 to 13.8 volts at idle and my fan is spinning faster than ever helping to keep the big block cool and my battery is staying fully charged. Thank you again for your assistance. Cliff
