shakav Posted September 14, 2009 Share Posted September 14, 2009 Hi All: My carburated Lt1 install in my datsun 240Zis almost done. I was wondering if someone could help me with the alternator hook-up. I had cut the alternator connector off the LT1 harness which had a single pink wire. I assumed this was the field wire. I had converted my old charging system to a single wire alternator from a 1985 nissan 300zx and it had worked flawlessly. I had put an inline diode on my field wire when I did my old upgrade. This kept the alternator from back feeding the ignition circuit. I have the 1996 camaro service manual but it is no help. I may in fact have a bad alternator. If have bus voltage to the pink wire but I am not getting any output from the alternator. If someone had a simplified wiring schematic that would help. The connector has holes for 4 pins and there are 4 pins on the alternator but only one pink wire. I do not know what the other pins on the alternator are for. Is there a simple test to see if the alternator is any good? I would also like to post some pictures but do not know how..... regards Paul Shakalis Quote Link to comment Share on other sites More sharing options...
deja Posted September 14, 2009 Share Posted September 14, 2009 The LT1 only uses the pink wire (second pin from the outside of the connector) The other pins are unused. You can take the alternator to most parts stores and they can check it for free. Hi All: My carburated Lt1 install in my datsun 240Zis almost done.
